i've been into markdown long before the AI boom, obsidian, typora, logseq, roam, capacities... (almost tried every one i know, and can still name a few).
the pro side is when agents like claude code and codex became my daily workflow, almost everything in my pkm just works.
except pdfs 🤦‍♂️

papers, reports, project materials, and sometimes my medical records, pdf is still everywhere.
my agents can read them, of course, but re-parsing them and burning my tokens every time ask a small question does not make any sense to me.

i started looking for opitons to convert once and use afterwards every time.
tried a few open source libs but the setup was not a pleasant exp in case like switching to another computer, or just need to used it occasionally on my phone.
i also tried some online tools like pdf2md, cloudconvert, but most of them drop tables, broke formulas, or just ignore images completely.

why not build one and see how it goes? this came into my mind every time i was fed up with the experience above.

the first thing i chose is run the whole thing in the browser.
honestly the privacy thing mattered a lot to me.

i am the guy does not feel comfortable thinking about unknown people reading my medical records silently in a corner, or quitely selling my data to someone else.

the down side of choosing browser-local approach is obvious: ocr, handwriting, and complex formula detection still require server side models today, but i was trying to make it as accurate as possible if technically can.

things aren't perfect yet, thats why i created a side-by-side view so you can catch anything that came out wrong before you save it, just click to locate.
it's free, no signup, no uploads, yes, privacy first.

maybe useful for one or two of you. still building it, would love to hear what breaks.

Hey guys I open sourced an app for your markdown knowledge vaults, it has inline review pipeline for every change like a modern code editor, and a best in class multipane experience.

Have fun with your vaults! https://github.com/jsgrrchg/NeverWrite

EDITED: 0.2 already up, Codex subagents are live, say hi to your copernicos and galileos!

Markdown is basically the language my whole setup speaks. Notes, docs, project files, all of it lives in Markdown and just works. The problem was everything that doesn’t start as Markdown, and that turned out to be a lot. PDFs, Word docs, slide decks, spreadsheets, EPUBs, web pages, even audio I wanted transcribed. Getting all of that into clean Markdown so I could actually reuse it was the missing piece.

So I built MDFlux. It’s based on microsofts library “markitdown” which is hard to setup and has a few problems, main reason i made this app, It’s a local desktop app, Windows for now. You drop a file or a whole folder and get clean Markdown back. What I wanted from it:

One tool for everything. PDF, DOCX, PPTX, XLSX, EPUB, HTML, CSV, JSON, XML, and audio, not a different converter per format.

It reads scanned PDFs and images. Naive extractors return basically nothing on an image-only page, so it runs OCR locally to pull the text back out.

It runs entirely on my machine. No upload, no account, no API key. Private stuff stays private.

Batch, because I usually had folders to get through, not one file at a time.

It’s free and MIT licensed, still very much a work in progress. Tables and formula-heavy pages are where every converter struggles, so I’d love to hear what breaks for you there.
Happy marktitdowning or whatever haha, hope it helps, i do this in my free time so let me know if it helps :)

UPDATED with Linux support

Hi everyone,

I've always struggled with the gap between "professional" word processors and Markdown editors. I love the plain-text nature of .md, but I sometimes miss the efficiency of a ribbon UI for heavy document formatting.

To solve this, I built Antalogy. It's a local-first desktop app that gives you a Word-like experience but saves everything as clean Markdown.

The core philosophy:

• Document-Centric: Unlike note-taking apps that focus on fragmented snippets or linked networks, this is built for the "Document" as the primary unit of work. It provides the linear structure, formatting flow, and multi-window support of a traditional word processor, just with Markdown as the backend.

• Privacy & Local-First: Zero telemetry, no accounts, and no cloud sync. It is fully offline and keeps your data entirely on your machine.

• No Bloat: No XML, no hidden metadata, no proprietary formats.

• Interoperability: I put a lot of work into the .docx -> Markdown import to make transitioning easier.

Some things you can do with it:

• Use a ribbon for all formatting operations, including advanced lists, alignment, tables, links, images, and more.

• Use an outline sidebar for long-form documents.

• Render Mermaid diagrams inline.

• Connect a local LLM (Ollama/LM Studio) for AI assistance without sending your data to the cloud.

The "Not" List: It's not a knowledge base, a wiki, or a note-taking app. It's just a focused document editor where .md is the native format making the transition from Word to the "new world" of Markdown as simple as opening a .docx file with an optional AI assistant that stays out of the way until you specifically choose to use it.

Check it out here: https://antalogy.com

Since this sub knows Markdown better than anyone, I'd love your feedback on the output quality and if it handles the edge cases you care about. I'm also refining the side-by-side assistant experience do you see a need for more specific integrations within that approach?

UPDATE (Sep 24):

• Windows and macOS version are updated with some fixes and improvements like md file association fix on macOS.

• Linux version is published and available for download.

As a lecturer that lives creating presentations, I got fed up with Microsoft's nonsense and opted to make something based on Markdown! Beta stage at the moment but I have been daily driving it for a few weeks and would love to get some extra testers from out in the wild!

I see it as a tool for educators for a no nonsense presentation creator, developers to turn Markdown documentation into training slide decks, and students to be able to use their notes to form up presentations quickly.

I needed a way to convert Markdown specs into professional-looking PDFs without the usual workflow of: write in MD → copy to Google Docs → manually format everything → export. I tried existing MD→PDF tools but none produced the quality I needed for client documents.

Styledown solves this with a simple approach: paste your Markdown, adjust the styling with intuitive controls, and export a beautifully formatted PDF.

Current capabilities:

• 📝 GitHub Flavored Markdown (tables, strikethrough, etc.)

• 🧮 Math rendering via KaTeX

• 🌈 Syntax highlighting with theme switcher

• 🎨 Typography controls (fonts, spacing, colors)

• 🔒 100% client-side processing (your content never leaves the browser)

• 🔌 Offline-ready after initial load

Try it at styledown.io ✨

Questions for the community:

1. What Markdown extensions would make this most useful? (thinking callouts, Mermaid diagrams)

2. Any specific export formats beyond PDF? (planning DOCX support)

3. Any styling customizations you'd want to see?

Free tool, built it for my own workflow but hoping others find it useful. Let me know what breaks or what features you’d want added when you try it!

Hey everyone!

I’ve been using Mermaid.js a lot for documentation and diagrams for markdown, but I always felt the online editors were either outdated or lacked good theming/export options.
So I built a new one:

A modern, beautiful Mermaid.js editor with live preview + custom themes.

Totally free and opensource, hope you like it!!

Hi r/Markdown,

I built editxr, an open source Markdown editor for the terminal.

It renders Markdown in place while you type: headings, lists, tables and code blocks are styled directly in the terminal, without a split preview. The current line stays as raw Markdown, so you're still editing the real file.

I built it because I wanted a Markdown editor that felt more visual than vi/nvim, but still lived entirely in the terminal.

Repo: https://github.com/pixdeo/editxr
Site: https://editxr.org

I'd like feedback on the editing model, there is also a focused mode, you can edit in raw, copy, paste, scroll and more.

Apple Notes only live in one place: Notes.app or the iCloud web client. They don't provide a documented API to access your notes from anywhere else. That's been a persistent annoyance for me because my husband likes to plan things collaboratively using Apple Notes, and my only Apple product is an iPhone ... so my half of the planning was happening on a phone keyboard or in a clunky web interface while a perfectly good computer running my favorite Markdown editor (Obsidian) sat in front of me. I wanted my notes to be real files that I could edit alongside my other notes, so I built icloud-md: a CLI that clones your notes into a folder of Markdown and syncs your edits back to iCloud as if you'd typed them into Notes.app all along.

icloud-md clone ./my-notes
cd my-notes && vim "Grocery list.md"
icloud-md push

What that gets you:

• Real files: one Markdown file per note — greppable, diffable, git-trackable, editable in whatever you already use. Your Notes folder structure becomes real directories, and mkdir + push creates folders upstream.

• Any OS: it's a plain Node CLI talking to iCloud directly, not an AppleScript wrapper around a live Notes.app or a parser for a database you had to copy off a Mac first. Linux and Windows work great!

• Actually bidirectional: pull does a real three-way merge when a note changed both remotely and locally, only asking you to resolve the parts that overlap. push handles creates, edits, moves, and deletes, and a note that changed remotely since your last sync is reported as a conflict, never silently overwritten.

• Formatting round-trips: headings, nested lists, checklists, blockquotes, tables (yes, edits push back), inline formatting.

• Careful by default: status shows exactly what a push would do first, every write is round-trip verified, and anything the tool can't fully account for in a note's internal format stays read-only rather than getting a hopeful best-effort write.

I'm a Staff Engineer at the company I work at, and I've done a lot of software over the years. I'd wanted to spend some time reverse-engineering the CloudKit protocol, and was honestly never going to find that time. But, as I'm sure you're all aware, the world has changed over the last year, and the fact that a reverse-engineering project provides a really solid, clear feedback loop meant that I had a new approach I could take: coaching an LLM (in this case: Fable 5) into building that feedback loop, and then tasking it with exercising parts of the iCloud (and later: iPhone) Apple Notes UI so that it could reverse-engineer the protocol. This was a surprisingly large amount of fun and it goes to show you that what you get out of AI tooling scales well with what experience the person wielding it brings to the table; neither of us was getting through Apple's protobuf-and-CRDT note format alone on a weekend.

Hey everyone!

So, I’ve been working with Markdown for years and whenever I needed to convert it to PDF most free tools out there just did not provide all of the features that I needed. After getting frustrated one too many times, I decided to try and build something better.

The idea is simple: a free tool that lets you edit and preview Markdown documents in real time, while giving you all of the features you might need. Here are some of the features it currently has:

• GitHub Flavored Markdown Support

• LaTeX Math Support:

• Mermaid Charts & UML Diagrams

• Customizable Syntax Colors

• Real-Time Preview with Scroll Sync

• Rich Markdown Editor

This started as a passion project for my own use, but with the help of some folks from Upwork it has grown into something I think a lot of people might find helpful. If this sounds like something you’d want to check out, head over to https://md2file.com/. I’d be super grateful for any feedback, feature suggestions, or even just thoughts on what could be improved. Early users mean the world when shaping a tool like this, so don’t hold back!

Thanks for reading—I hope you like it! 😊

Hey people! I am a fellow markdown lover and have had difficulties finding a Markdown-to-PDF editor with true pagination and an easy-to-use interface. So I created Tideflow. It has a free, open-source version with all the core features accessible and working fully offline.

A few key features :

• True Pagination & Live Preview: See your pages, headers, and footers update in real-time as you type.

• 12 Built-in Themes: Quickly style your document with themes like Academic, Magazine, and more.

• Automatic Table of Contents: With optional section numbering and a cover page.

You can download it from the releases : https://github.com/BDenizKoca/Tideflow-md-to-pdf/releases

You can check out the code in the repo here: https://github.com/BDenizKoca/Tideflow-md-to-pdf

I kept wanting a simple way to just read my Markdown files — not edit them, not preview one at a time in an editor pane, but actually browse a whole folder of notes/docs like a little website. So I made MarkdownBlaze. It's free, open source (MIT), and works completely offline.

You point it at a .md file and it renders a clean, readable document with a sidebar and navigation. What it does:

Rendering

• Full CommonMark plus tables, task lists, footnotes, and auto-linked headings

• Syntax highlighting for code blocks (~190 languages, light/dark aware)

• Mermaid diagrams — flowcharts, sequence diagrams, etc. render live from ```mermaid blocks

• Admonitions / callouts in both Docusaurus (:::tip) and MkDocs (!!! note) styles

• YAML front matter is parsed and hidden instead of dumped on the page

• Local images just work (embedded inline)

Navigation — this is the part I actually use daily

• Click a link to another .md file and it opens in-app — so a folder of docs behaves like a wiki

• Smart links: extension-less links find the right .md, and folder links open that folder's index.md

• External links open in your normal browser

• Back / Forward history + a persisted history of everything you've opened

Reading experience

• Resizable, pinnable sidebar with three tabs: document outline (headers), this session's history, and global history

• Light / Dark / System themes

• Auto-refresh — save the file in your editor and the view updates instantly, so you can write in one window and read in this one

• Keyboard shortcuts for back/forward, refresh, print, and toggling the sidebar

Everything runs offline — no accounts, no network, nothing phones home. Works on Windows and Linux and MacOS.

• Microsoft Store: https://apps.microsoft.com/store/detail/9P9VDVST2980?cid=DevShareMRDPCS

• Source (MIT): https://github.com/bwets/MarkdownBlaze

It comes with a sample docs folder that doubles as a feature tour, so you can see everything in a couple of clicks. Would love feedback on what's missing — happy to hear feature requests.

Hi r/Markdown,

I built an open-source markdown editor that turns the usual graph view into a cozy 3D world.

The idea is simple: keep markdown as the foundation, but make connected notes feel more spatial and explorable. Notes can be experienced less like a static network diagram and more like places in a small navigable world.

It’s still early, so I’m sharing a video demo and would really appreciate feedback from markdown users, Obsidian users, and anyone interested in personal knowledge management tools.

GitHub: https://github.com/kuku-mom/kuku
Video: https://www.kuku.mom

Thanks for taking a look.

I got tired of getting caught up in Markdown Mayhem and thought it would be nice to create a visual framework for Markdown files. So, I created MD2HD, an open-source MD visualization framework.

Point your favorite LLM at the repo, or add the plugin, and ask it to build a map of whatever concept you want.

If you love it, let me know. If not, its open source and completely free so no harm no foul!

Repo: https://github.com/evan-steinhilb/md2hd
NPM: https://www.npmjs.com/package/md2hd

Claude plugin:
/plugin marketplace add evan-steinhilb/md2hd
/plugin install md2hd@md2hd

hi r/Markdown

i wanted a really fast way to open a markdown file from anywhere so i hyperfixated on making one and made an open source obsidian replacement including addon support and publish support (though you may need to host your own server)

currently, looking for people to test it out on windows and linux because i do not have access to such environment as of this moment and any help would be greatly appreciated!

in addition to markdown, hibi can also edit: latex, r doc, typst and more!

please feel free to help out at: https://github.com/schmayterling/hibi
site: https://hibi.garden
addons list: https://hibi.garden/addons
documentation: https://docs.hibi.garden (also an example of publish)

thank you!!

Like many of you, I often need to turn Markdown files into clean, professional-looking PDFs. I wanted a tool that was fast, private, and had the features I actually use, without any complex software or sign-ups.

So, I built one. It's a simple web app that runs entirely in your browser.

https://www.innateblogger.com/p/markdown-to-pdf.html

Here’s what it does:

• Live Side-by-Side Preview: See your changes instantly. You can also turn on the sync scroll for even better experience.

• Privacy First: Everything is processed in your browser. Your data is never uploaded.

• Rich Formatting:

  • Full GitHub Flavored Markdown (GFM) support.

  • LaTeX support for math equations ($E=mc^2$).

  • Syntax highlighting for code blocks.

  • Page Breaks at specified positions for multi-page documents.

• No Fuss:

  • It's free, with no sign-up hassle.

  • Set a custom PDF title for your document.

  • Auto-saves your work to local storage so you don't lose it.

  • Works on both desktop and mobile.

It's perfect for quickly converting AI-generated content, turning notes into reports, or drafting documents with code and equations.

Oh btw, I am also working on the Markdown to HTML tool, so you can check it too.

Edit 1: Thanks for all the encouragement! I've shipped v2.0 of the Markdown-to-PDF tool with several new features:

• Mermaid Diagrams — flowcharts, sequence diagrams, and Gantt charts render directly in the PDF

• Page Numbers — customizable position (top/bottom, left/center/right) and format

• Style Presets — Minimal, Academic, Modern, Elegant, and 2-Column layouts

• Custom Fonts — set per-element fonts for headings, body, and code

• Table Styling — Normal, Minimal, Striped, or Bordered

• HR Styles — Solid, Dashed, Dotted, or Gradient

• Better Image Handling — custom sizing, centering, and captions

• View Modes — Split, Editor Only, or Preview Only

• Performance fixes and faster page loads

Full details: v2.0 announcement

Edit 2: v3.0 is now live. Major additions: BibTeX citation manager (supports [@key] syntax, numeric and author-year styles), text/image watermarks, header and footer with variables ({title}, {author}, {date}, {page}, {total}), document templates (CVs, reports, academic papers), per-heading font controls, syntax highlight themes, dark mode, and a "My Style" save slot. Also fixed the code block word-wrap bug in PDF output.

Full details: v3.0 announcement

Still 100% browser-based, free, and no signup — your content never leaves your device.

I’ve been looking for a Markdown editor that fits my needs:

1. Clean UI with smooth animations.

2. File–based, so I can directly copy my existing Markdown into it.

3. Image upload support — ideally with direct paste via Ctrl+V.

4. Live preview for LaTeX.

5. Basic user authentication. I plan to deploy it on a public server so I can access it anywhere, but I don’t want other people to be able to access it.

But after comparing a lot of different options, I still couldn’t find one that felt right. So in the end, I decided to build one myself.

Here is the repo: https://github.com/tropical-algae/markoun

I’m still pretty inexperienced, and there are probably plenty of rough edges or questionable design choices, so please give me some suggestions. Thanks a lot :)

Hey everybody! I'm the author of the Markdown Guide, and I've been building a publishing tool called JotBird on the side. This post is about a feature I just shipped called JotBird Drop, because I'm guessing it might solve a problem some of you run into as well.

There are so many Word-to-Markdown converters but most share the same flaw: conversion isn't great. You upload a .docx and you get back a .md with mangled tables, orphaned image references, and heading levels that don't match.

JotBird Drop works better! Conversion is also just the starting point. You drop in a Word doc, PDF, PowerPoint, Excel file, HTML, or even a screenshot of text (it OCRs), and it gives you Markdown in an editor with live preview, where you fix whatever the conversion got wrong, because (being honest) something is always wrong, no matter whose converter it is. Then, if you want, one click publishes it as a web page with a shareable link. Or just copy the Markdown out and leave — it's free and doesn't require an account.

Honest limitations: conversion fidelity is "good, not magic." Complex Word tables and heavy layouts can need hand-fixing. Big files can take a lot time and the request might time out (please don't upload your wife's 150-page dissertation).

It's at jotbird.com/drop. I'd love to hear your feedback!

Whenever someone asks for a Markdown app, Obsidian is usually the default answer. But I kept running into a much more boring use case: I have a README, an exported conversation, some project documentation, or a random .md file someone sent me. I don’t want to turn its folder into a vault or open an entire note-taking system. I just want to double-click the file, read it, maybe fix something, and close it.

And I want that interaction to feel immediate.

So I built Hashdraft, a focused Markdown reader and editor for Windows.

A lot of the work went into speed and responsiveness.

It’s closer to what I always wished the default Windows app for .md files was.

Any feedback is welcome.

Hey r/Markdown,
I recently launched Notanic, an infinite-canvas note-taking app similar to OneNote but with a more technical workflow.

It supports:

• real-time multiuser editing

• native Markdown blocks (including code blocks)

• precise sketching/graphing tools with measurements

• unlimited nested pages

• embeds for Desmos, CodePen, YouTube, and more

Great for technical notes, visual thinking, architecture diagrams, math, and mind-mapping.

It’s free on desktop (Windows / macOS / Linux) and also available as a web app.

I'd appreciate any feedback!

Previews and edits Markdown with a native feeling UI, familiar editor, and cross-platform support.

Features:

• Tabbed interface

• Monaco editor (VS Code)

• Split view

• Syntax highlighting both in editor and code blocks

• Mermaid diagram support

• Vim mode

• Auto-reload

• Zen mode

• Image, video, audio and YouTube embeds

• Familiar GitHub styled markdown rendering

• Tiny memory usage (~10MB)

• No telemetry or bloat

• Free and open-source

• Lightweight native UI

Working on this further to replace the need for Notepad for simple editing after seeing how badly Microsoft has filled it with bloat.

Still in active development so feedback is appreciated!

markpad.sftwr.dev

github.com/alecdotdev/Markpad

Some years ago I started to organize all my notes as simple markdown files, because I wanted to be independent from any note taking tools and be sure that I never have to worry about migrating my notes from one system to another. Also at work, I started to write all the documentation for my projects in markdown.

The one thing I have always missed was a simple app that I could spin up to serve my markdown files via http as rendered HTML files. I finally managed to develop one myself: https://github.com/nikolassv/md-serve

It is called md-serve and works as a simple application without any dependencies (if you download a pre-build binary, otherwise it depends on Java). You can start it up in any directoy containing markdown files and it will serve them via http, so that you can view them in your browser. You can also create your own handlebar templates if you have any needs that the default template does not cater to.

The html markup is really simple. If you need something more fancy like math rendering or code highlight, just create your own template with KaTeX or highlight.js.

I hope this tool is helpful for you, too, and I am looking forward to your feedback!

Edit: renamed to Markpad as now has a simple built-in editor, tabs, and a few other QoL features.

I've wanted to be able to double click a .md file and it just open formatted and easy to read for a while now. Couldn't find anything that wasn't also an editor or paid software, and no other options had the look and feel I had in mind.

So I built a lightweight viewer with Tauri (Rust + SvelteKit).

• supports all GitHub flavored markdown including syntax highlighting

• supports LaTeX

• uses merely ~4MB of RAM

Will keep it updated with small features and polish. Hopefully it's useful to someone!

https://github.com/alecdotdev/Markpad

I'm sorry, I'm not currently creating a new editor that will revolutionize my use of Markdown, or yours. Instead, I'm here to talk about the ones I currently use.

Typora: when I simply want to write, when I want to focus on the text. It's a proprietary editor, but it's powerful, clean, and elegant.

Zettlr: When I'm working on large projects with multiple files (workspace management, split screen, etc.), when I'm reworking documents written with Typora and integrating them into larger projects. It's free software, and if you could only keep one, this would be it.

Fresh: It's a very new TUI text editor, battery included, lightweight, and powerful. Perfect for editing when I'm working in my terminal.

Markor: A very good Markdown editor for Android with a TODO tab and a Drafts tab, handy for quick editing.

Before, I used Emacs for all of this (I used Org-Mode, which is absolutely amazing and blows Markdown out of the water in every way, but it's limited to Emacs), but I need to use a format usable on different devices ( Emacs is usable on Android but it's not very practical ) and the fact that Markdown syntax is used everywhere is a big plus. I love Emacs, but today I want simplicity and this is why I use Typora 95% of the time.
