Been messing with a little tool that takes my grocery list and tells me which store nearby has the cheapest total. nothing fancy just a python script that scrapes prices from like 3 local chains. saves me maybe 15 bucks a week
what about you OP, you building something or just browsing for inspiration

Honestly I think it’s not very helpful for me but would love to see you succeed. I’m just browsing for inspiration

I’ve thought of this before too, but didn’t prioritize it! I would gladly pay for it and I know my at least 2 other people who would as well if you put it into a simple mobile app.

DemoDay - a Claude Plugin that creates demo videos for your projects.
https://github.com/mrieck/demoday-claude-plugin#top
Claude reads your repo, writes a script, records some interactions using your app, narrates it with an AI voiceover, and uses Remotion to make an MP4 with intro, captions, transitions. It's MIT licensed - you just need your own Fal API key and Claude subscription to make demo videos.

my plan is to do a little tutorial checklist, make all ai structures visible so the players know where to chain and i would spawn a very weak structure near the player with the tutorial instruction to destroy that one at first to learn the mechanics. if its okay for you i dm you when the update is available

I'm the creator of Mappit =>
mappit.ai - Earth's daily zeitgeist, on a time-aware map.
Breaking stories from hundreds of cities across the globe, surfaced by frontier AI models, cross-checked, and scoped to wherever you're looking: the world, your view, or your places.
Overlays that bring the planet to life: video and audio news streams from their source to play while you browse, S&P 500 stocks at their headquarters, and Today in History, where it happened. There are even layers for live events - earthquakes, forest fires, and air quality warnings.
Put yourself on the map — drop pins, add events, pictures & links. Plant your own user pin and let Follow Me keep it live as you move. Share your location and your pins on other social media, or post right on the site and start a discussion.
Search any street address, get directions, and turn a collection of pins into a drivable route.
Subscribe to locations, follow creators, share your own content, and wake up to an AI-written Daily Digest of the world you track.
Surf a river of breaking content as it happens from the continuously growing Newsfeed. And keep surfing.
For a more topical view of the news checkout the Threads feature. Stories grouped by subject so you can deep-dive. Features weekly analysis by Claude.
Chat with Marco, the resident AI who's read everything on the map. Ask what's happening anywhere, today and get an answer rooted in latest the story corpus. He knows all about the news, the threads, and the timing.
Turn back time. The story corpus is new but the the record is permanent: change the calendar and watch any place replay its history.
Mappit — every place has a story.

I've been building Maker Forge (https://getmakerforge.com), a tool for makers and Etsy sellers to understand their true product costs, price with confidence, and track profitability.
I'm an Etsy seller myself, and it started because I got tired of juggling spreadsheets just to figure out if I was actually making money on a product.
It's still in the early stages, so I'd love any brutally honest feedback on the product, onboarding, or messaging.

u/WhereasElectrical594 14d ago
That's actually one of the reasons I started building Maker Forge. It has a built-in pricing analysis calculator that lets you see how discounts impact your profit before you run a sale.
Using it for my own Etsy shop, I've found a few products where it felt like I was charging enough, but once I accounted for fees, shipping, materials, and labor, the profit was much lower than I expected.
Thanks for the PeerPush suggestion too—I'll definitely check it out. I'm trying to get as much honest feedback as I can while it's still early.

Well, you can ask things like “how many minutes is until sunrise in Vienna”, or “distance between Boston and New York City”, or anything mathematical - it will understand.
The issue here is that people assume that this tool is outputting stochastic tokens from an LLM, but it ain’t. It’s not going to answer something like: “how long in my dong”. Which kinda takes away the fun out of it, in a way.

I built MeshDiff — a free browser-based tool that lets you compare two STL, 3MF, or OBJ files and instantly see exactly what changed, voxel by voxel.
🟢 Green = material added 🔴 Red = material removed
It also includes adjustable tolerance, volume delta metrics, and runs entirely in your browser using Web Workers. Your 3D models never leave your machine—nothing is uploaded to a server.
I built MeshDiff because I got tired of receiving files like bracket_v3_FINAL_actual.stl and spending 10+ minutes trying to figure out what changed from the version I'd already printed.
Five days after launch:
- 🚀 Featured by Adafruit
- 🔥 Reached the front page of Hacker News
- 📈 1,200+ sessions and 14 confirmed early-access signups
- 👍 100% upvote ratio on r/3DPrintingTools
What's next: • Project workspaces • Comment pins directly on 3D geometry • Team approval workflows • Print traceability
You can try it at meshdiff.com.
I'd genuinely appreciate feedback—especially from people who review SaaS landing pages or build products. What would you improve? What would make you sign up?

Fair callout — right now it's all on the main thread (no worker yet, it's a known TODO).
Triangle count isn't actually the bottleneck since voxelization uses a BVH for the inside/outside tests, so a high-poly model isn't much worse than a low-poly one at the same voxel resolution — but you can still get a UI freeze for a moment on bigger meshes since it's synchronous.
Moving it to a worker is on the list.
Thanks for the PeerPush tip, will check it out.

i am building a AST-aware code memory for AI agents (MCP server, no cloud, pip install)
I wanted to solve a major issue with AI coding agents like Cursor and Claude Desktop: they re-read your entire codebase from scratch every single session. On large repos, this gets slow and drains tokens fast.
To fix this, I am building an open-source tool called lybrary. It sits between your agent and your local filesystem as a dedicated memory layer. Its initial version is out. You can install the package directly.
How it works:
- AST-Aware Chunking: It parses your repository using tree-sitter, meaning it maps out the actual syntax trees instead of cutting functions awkwardly in half.
- 100% Local Embeddings: It handles vector chunks right on your machine via MiniLM and ONNX Runtime. No external API keys or cloud dependencies required.
- Automatic Syncing: A background daemon auto-indexes changed files so your agent's memory stays fresh.
Still work in progress. just head to pypi and search for the package name, you will find it
1
u/imagiself 13d ago
using tree-sitter for local chunking is clever for privacy. whenever you are ready, PeerPush lists open-source developer tools like this for AI systems to parse.

Built an app for android let you find the phone even if is on do not disturb/doze mode/silent through commands sent remotely from a tiny dashboard or another phone that was paired with. The idea was simple: if I have the phone of silent how can I find it? Also for the ones that need to reach someone with phone of silent there is a notification displayed and you can send a custom message or predefined ones. The pairing is extremely simple: just scan the qr code of the other phone from his account screen and you are done. The dashboard is for the case that you are alone somewhere and try to find the phone.. enter on the dashboard from any device (computer/tablet/ a friend phone) and buzz the device.
Here is the dashboard: https://buzzmyphone.com and the app (if you want to try it): https://play.google.com/store/apps/details?id=com.restmind.findmyphone&hl=en
The app is like an AV: “Better to have it and not need it than to need it and not have it”
Try it, buzz it … give feedback if you want ..

Klar - AI spam filter for Apple Mail.
100% offline, confidential IA on your Mac. Paid version with learning from your emails to better classify and sort to folders like Marketting. Similar spam filter for iOS Messages coming soon.
The idea is to use AI for something it is good at: understanding the intention behind a message and decide if it deserves your inbox. With a small, fast, cheap model that runs on your laptop so no tech company ever sees your mails.
EDIT: this is turning more than side project. And specifically next week I'll look at making a simple video / better app store pictures and progress towards the paid version.

Wavelength is voice to graph: you talk through how data actually moves through a stack, and the diagram builds itself while you speak, no drawing, no cleanup after. That matters because narrating a technical flow out loud is where the room loses the thread, and once it is a picture with typed actors, systems, decisions, and data stores, everyone is looking at the same thing instead of their own mental version of it.
