alt Hacker NewsAsk HN: What Are You Working On? (April 2026)
What are you working on? Any new ideas that you're thinking about?
Comments
Software to host podcasts. The standard is relatively easy, but getting everything right takes some effort
I'm training a latent diffusion model on weather radar data to predict short-term storm behavior. Decent results so far on downscaled data at +30min, training a full-res model at +1h and +2h horizons now. Excited to see how it does!
I've been hacking on gaffer (https://gaffer.sh) as a way to learn and explore agentic development. It's been fun and I've even picked up a couple customers.
Shoggoth.db : a self organizing database to experiment with agents without having to let them roam freely.
Posted a show hn earlier today that didn't got any traction : https://news.ycombinator.com/item?id=47738516
A news aggregator like HN but specifically for freight: https://news.freight.nyc
The idea is mostly to build a community for the sector I work in, since there isn't any (aside from Reddit...)
http://grandpacad.com - 3D Modeling tool intended for creating 3D prints. AI based. Allows for dimensionally accurate parts as well as organic shapes.
I massively improve it every month. Pretty proud of it.
Fungi vision detection on the browser. Offline
Trained to detect a few thousands species pretty accurately in near real time.
Now working on expanding to far more species and exploring other CNN architectures.
I’m working on https://hilogame.cc It’s a word guessing game based on binary search. Only having around 10 users for now, but hope more people will find it fun.
I am working on hugind, I have two goals:
- make it reliable to run LLM inference on company hardware, even when it is poor or outdated
- bring chaotic agentic behavior under control in business contexts
I built a local tool that uses ollama to transcribe my handwritten journal pages into obsidian pages.
I'm also just working on my game, Antorum Online. Made with Rust and Unity. https://antorum.online
A really simple link-in-bio service:
Mostly just wanted to learn Django and Vue and see if I could get something working online. Have a handful of free users, so that’s kind of exciting!
Building https://vazi.io/ - AI intelligence for your brand. Basically AEO for your brand / website
I was tired of setting up additional read replicas and Snowflake for our BI teams, I built an analytics database using S3 and DuckDB.
Still working https://pagewatch.ai/ , my ai readiness audit tool. Currently having fun building a MCP app for it inside Claude / ChatGPT, its oddly tricky to get things behaving consistently.
I built a lightweight (<1mb) chrome extension (with over 600,000 downloads) that lets you chat with page, draft emails and messages, fix grammar, translate, summarize page, etc.. You can use models from OpenAl, Google, and Anthropic.
Yes, you can use your own API key as well.
Building offline music player for macOS for past one year https://github.com/kushalpandya/Petrichor
Currently working towards a big release to go out by end of the month.
StoreRun.app. It transforms grocery shopping from a chore into a collaborative experience ... still private beta and about 75% there but you can kick the tires for the non-sync version.
Feedback welcome
DrawX is Excalidraw with backend.
I love Excalidraw but I don't need Excalidraw+ I just need the backend where I can save and be able to create multiple canvases.
So that's what I built!
Building Chameleon - a Chrome extension that adds switchable "lenses" to Gmail. The first one scrambles text so people nearby can't read your screen. ~100 organic users across 14 countries. Solo founder, pre-revenue.
I am working on a simplistic syntax for mixing any text with structured knowledge (links, triples, property graph)
Syntax..has name..ddot.it
The spec is ready at https://ddot.it, now working on tool support.
Runway, a CRM. It's looking great, near to its first public release, built on market standards. If anyone's interested just ping me, mail handler on profile, ciao. p.s. still wondering about the licensing to adopt to balance different matters/desires.
I am creating ai website builder https://playcode.io/ai-website-builder, the full stack part.
I have been working on it for 10 years already.
Building Ayla - a period, ovulation, and pregnancy tracking app for iOS/Android. Everything is stored locally on-device by default. Solo developer building with Flutter.
We are working on making agentic ads and regulatory compliance scalable.
Just launched the blog too
I am working on a curated Christian church directory/portal that will help individuals find their church home, as well as offer a platform for churches to effectively have a web presence at a free entry price.
https://k8slogjedi.netlify.app/
working on an AI-native Kubernetes sidekick that watches your pods, reads the logs, and turns failures into clear fixes before they become outages
I'm building a platform for businesses to get more reviews and deflect negative reviews:
I am hoping to launch in about a week, so I would love any user feedback! (email in profile)
A privacy first transcription and analysis app for iOS and native Mac OS (latter this week)
All AI runs on device, nothing ever leaves your device apart from syncing data via your iCloud.
My wife has wanted a security system for a while. The turnkey cloud solutions freak me out. I've done some home automation with home aisstant before, and omg that was configuration slog. But with Claude..... It becomes fun.
Working on implementing the web both auth standard and a take on federated and out-of-band agent bot validation.
Working on an RL pixel platformer sandbox to learn RL and explore self-play with a playable RL agent. It’s a cross between JumpMan Jr and Spelunky 2.
Very early demo with a smart dum-dum RL agent here:
Music player, organizer, discovery tool that will load history and subscriptions from streaming services and discogs, last.fm etc and allow you to query it with AI.
A work in progress.
Tools for llms for developers. Unix philosophy, pipes. Repository maps for a quick overview. Hybrid search for finding knowledge, tools or skills. Linter for tools. External tools provider, not MCP. Having a blast.
I’ve been building a toy for exploring elliptic functions, modular forms, and elliptic curves. Sorry mobile support is not there yet.
I'm working on my Open Source speaking clock (mostly for myself):
https://github.com/jcubic/speaking-clock
It uses local AI models for the voice.
Nothing fancy, building a local platform to rent/rent-out video games.
Coming from a place where buying games is very expensive, and gaming is an expensive hobby in general.
Tried rotating games locally between friends and friends of friends, now scaling it up.
Python DSL for safe quantum programming that compiles to Qiskit, where the type system enforces coherence and ancilla cleanliness
I built a Mac app (https://revryte.com) that replaces the ChatGPT copy-paste loop. It transforms text in place or inserts smart snippets in any app using AI.
CLI-first inventory management for EE parts. https://willwillems.github.io/tray
Fully local, hobbyist friendly, agentic workflows work great with it since it’s just a CLI.
I am working on a small Pascal IDE for iOS.
It runs code locally (written in Swift), includes examples, and has a Turbo Pascal–style theme for max nostalgia.

A solution set to the book Pattern Recognition and Machine Learning by Christopher Bishop.
I'm working on a major update for my macOS Hacker News reader, HacKit: https://apps.apple.com/app/id1549557075
Hey all, I made a free daily ecology cascade game. https://Trophle.com I'm in school for environmental science and I want to make educational games and resources
I miss Pocket, so building an article bookmark tool, with a focus on a nice reading experience - https://broadsheet.marginalutility.dev/
I’m building a web app that optimizes fdm 3d printing print profiles based on geometry, material, hardware etc.
Hopefully this can help people reduce filament usage and waste, speed up print times, and improve print quality.
https://agent-ci.dev: Run GitHub Actions on your machine. Caching in ~0 ms. Pause on failure. Let your AI agent fix it and retry, without pushing!
My wife made a silly browser based arcade style Kanban board management game called Kanban Chaos https://kanbanchaos.com/
I'm working on a sandbox for Linux terminal work with UX similar to Python virtualenv: https://github.com/wrr/drop
We‘ve built an AI image and video model gateway called https://lumenfall.ai.
Right now I‘m working on adding a „simulation“ mode, that allows anyone to get free fake responses during development, instead of pricey real generations.
