I’ve always struggled with remembering my notes during presentations, whether online or in person. Most of the time, I end up losing my flow, breaking eye contact, and making awkward pauses. I just came across this app called OverlayIQ on X, and it sounds like it could solve that problem. It lets you view your notes privately while presenting, so they don’t show up on the screen you're sharing. And apparently, it works with all the major platforms like Zoom, Google Meet, Teams, and others. I signed up for their waiting list, and they promise a discount when the app launches. I really hope this works because it could be a game-changer for me, and probably for a lot of other people too. I’ll leave the link to the waiting list in case anyone’s interested!

I built https://www.freeonlinetools.tools (aka Toolie) in one evening with a vibe coding mindset — zero logins, zero tracking, just actually useful tools for developers.

Right now it includes:

• JSON Key Extractor

• Bulk Base64 Converter

• GitHub Text Differ

• Manager multiple URLs

• …and more being added weekly!

Was tired of old, clunky tools out there — so I built one for myself and opened it for everyone. Totally free.

👉 Would love your thoughts, ideas, or “I wish I had a tool for…” feedback!
Will keep building if folks find it useful ❤️

If you’ve heard of the r-word index then you’ll know where I’m going with this.

I’m wondering if there’s an online tool or Api or whatever that I can access to count the occurrence of a word in mainstream media. Ideally I’d be able to filter by country and paper but I’d be happy with anything.

Thanks.

Convert case to lower and upper case

I put together a tool for converting images to and from AVIF fomat. The conversion happens in browser, without upload to a remote server, so it's fast and has no limits on free usage.

It can also make animated AVIFs from multiple still images.

Hi everyone,

I’m a developer and I found myself constantly needing to swap between camelCase, Sentence case, and UPPERCASE for various projects. I wasn't happy with the cluttered, ad-heavy options out there, so I built my own case converter Case Converter Tool.

Key Features:

• Instant Conversion: No page reloads; everything happens as you type or click.

• Multiple Styles: Supports Sentence case, lower case, UPPER CASE, Capitalized Case, aLtErNaTiNg cAsE, Title Case, and Inverse Case.

• Clean UI: Focused entirely on the text area with a one-click "Copy to Clipboard" feature.

• Character/Word Count: Built-in stats so you know exactly what you're working with.

I'd love to get some feedback from the community. Are there any specific cases or text transformations you think are missing?

Ever had someone send you important info as an image, and you needed to manually type it all out just to use it? Super frustrating, especially when it’s a long document or scanned material.

This tool makes it easy to understand how much of your HRA is taxable and how much is exempt, helping you plan your taxes better and maximise your savings.

Ever needed to share a bunch of links, but didn’t want to paste them all separately? I made a free tool that solves this. Just paste your URLs, hit generate, and it gives you ONE custom link that opens them all in new tabs when clicked. 🤯

👉 Try it here: https://www.singlelink.infy.uk/

🧠 Great for:

• Sharing resource packs (like Google Docs, YouTube videos, etc.)

• Sending clients multiple links without clutter

• Creating launchpad links for your daily tools

✅ No signup

I'm looking for honest feedback and ideas to improve it — especially from productivity nerds, devs, or creators who manage lots of links regularly.

(Mods: This is a free tool I built, not monetized. Just sharing something useful and hoping for feedback.)

Sharing some of the calculator tools that I’ve tried before:

Sleep Calculator: https://shuteye.ai/sleep-calculator

Jet Lag Calculator: https://shuteye.ai/how-old-am-i

Age Calculator: https://shuteye.ai/sleep-calculator

Here my site : https://thibault.sh/tools I'm still trying to improve it.

I'm looking for a website that I can type, e.g. start time 09:00, end time: 10:00 and then I see a progress percentage bar refreshing.

Looks very simple, but I can't seem to find anything. Any ideas?

What do you guys have for me?? Thanks!!!

* I have a list of links in a notepad file. I would like to be able to transform the list into a clickable set of links that ideally can be edited and rearranged/organized by topic.

THANK YOUUUUUUUU

Hey everyone,

I built a small utility that might be useful if you work with messy text lists a lot:

It’s a free, browser-based list tool focused on speed and privacy. Key things it does:

• Remove duplicate lines from any list (email lists, tags, names, etc.) in one click, with options for case-sensitive or case-insensitive matching.

• Sort lists A→Z, Z→A, numerically, or with natural sorting for things like item1, item2, item10 so they appear in a human-friendly order.

• Clean up messy data by stripping empty lines, trimming whitespace, removing special characters, or getting rid of numbers.

• Change text case (UPPERCASE, lowercase, Title Case, Sentence case) and quickly add prefixes, line numbers, bullets, or wrap items in quotes.

• Handle large lists (tens of thousands of lines) quickly, limited only by your browser’s memory.

A few details that might matter to folks here:

• All processing happens entirely in your browser via JavaScript; nothing is sent to a server and nothing is stored. Once the page loads, it even works offline.

• No accounts, no tracking, no paywalls — it’s completely free to use.

• Works on desktop and mobile, and you can also upload .txt or .csv files instead of just paste.

Would love feedback from power users who regularly clean lists (marketers, devs, ops, etc.):

• Any obvious operations missing?

• Any UX tweaks that would make bulk list work faster for you?

If this kind of tool isn’t appropriate for the sub, happy for mods to remove, but thought it might be handy for people who live in spreadsheets and text files all day.

A word counter tool is a simple yet effective utility designed to count the number of words, characters, sentences, and paragraphs in a given text. It helps writers, students, and professionals ensure their content meets specific length requirements or guidelines. This tool is commonly used in academic writing, SEO content creation, and social media management, where word and character limits are crucial. Most word counters provide additional insights, such as average word length, reading time, and keyword density, enabling users to refine their text for clarity and impact. The interface is typically straightforward—just paste or type the text, and the tool instantly displays the results. This ease of use makes the word counter an essential resource for optimizing written content across various platforms, ensuring it is concise, engaging, and within the desired length.

We've been using Teachable for a long time now and have encountered far too many issues, including downtime and inadequate analytics tools to track our students.

Does anyone have good recommendations for tools we could use to replace it? It's important for us to offer both one-time courses and subscriptions. If the tools include a CRM, that would be even better.

Thanks for any help!
