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
Trying to improve my fine tuned whisper through more custom dataset. I can still see it not understanding certain things currectly.
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 have started working on a standalone, self-hosted, service for an album club (music, that is).
Members takes turn pitching one album per week. Support comments and a handful of emoji-based reactions.
Integration with Spotify for easy pitching and playing (by links only, users are not required to have a Spotify account).
Plan is to keep the clubs fairly small and invite only.
Building it in Gleam which is a lot of fun!
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.
A fun project I'm working on: Chipmunkify. You upload a song and it isolates the vocals to give you a 'chipmunk' version while keeping the instrumentals untouched.
Have fun trying it and let me know what you think!
Building something that finally stops making me the tester for my own AI. You know that moment where the AI finishes writing code and then goes "can you run this and check if it works?" I got tired of that loop. So I built an IDE that just... runs it, clicks through it, finds what broke, and fixes it. You watch. Not Better Cursor , But what comes after it.
I am building ExamineIP - Free network security toolkit
Collection of 15 diagnostic tools (VPN leak test, DNS checker, port scanner, etc.) built after a WiFi security incident. All client-side, no data collection.
Feedback welcome!
I struggled finding mock exams when I was studying for the Einburgerungstest in Germany so i built a super simple site to offer folks some mock exams to practice with https://www.einburgerungstestpractice.com
I've revived a project I started around 20 years ago. It is a kind of graph query description/measurement tool for protein 3D data.
The query engine itself is like a DAG of 'operators', similar to a relational DB (or more like a graph one) with scanners, filters, and matchers.
Very fun, although not at all efficient and probably overengineered for what it does :)
Currently working on a way to help folks setup a signal account without requiring a smartphone.
It's in rust with egui, and should help folks to do that without the cli.
Not ready for prime time yet, but available at https://github.com/almet/signal-without-smartphone
After going to a bunch of bachelor parties over the past few years, and planning a few myself - I built an AI-powered bachelor/bachelorette planning tool to help make it a lot easier then it actually is
Check it out at https://bartyai.com
I'm building a workspace for thinking with AI. Think what Cursor did for coding, but for rigorous thinking.
I believe the direction toward persistent, proactive, remembers-everything AI is the wrong one for thinking. AI should be used as a selectively invoked sparring partner.
Month 4 of building a data management platform called Seaquel [1].
Months 1-3 were about building a desktop client. Now I'm working on a server binary customers can optionally self-host to share dashboards publicly and run workflow automations.
I am building a coding agent like claude code. Lambda agent, getting to learn a lot like how to control your context window how to conserve tokens. Check it out here https://GitHub.com/ayusrjn/lambda
We're building a python library that compiles revenue = price * volume into =B4*B5 in Excel — because the final user always asks for Excel in the end. https://modeleon.ai/
One of my current clients is an EV charging firm and realised the tech side is such a mess, though of doing a Parse/Firebase/Stripe for EV chargers and networks.
So people don't need to lose braincells over this till it actually matters.
Building a video game adaptation of Pass The Pigs (the "dice" game where "dice" are plastic pigs).
Early preview here: https://piggy-toss.netlify.app/
The goal is to play with friends, we love this game.
Grit Garden: https://grit.garden (https://github.com/pravj/wordle-garden)
Recently shipped this personal art project that turns daily Wordle attempts into gritty / struggle-filled stories, kinda similar to the emotional arc of the Wordle game play.
You can upload your own Wordle game screenshot to generate one for yourself.
In addition to completing what was once in the idea list, I got to learn about
- Prompt fine-tuning: Models are sharp enough to complete Wordle games quicker than human average scores, so I had to dump that down and get the average down.
- Karpathy’s Autoresearch: Experimented with auto-research for prompt fine-tuning, in addition to manual prompts.
- Vision models: While leading labs have multimodal models with quality visual reasoning, the benchmarks are still quite different for a simple Wordle analysis (reading what letters were yellow/gray/green); I also noticed labs/companies with separate vision models but their APIs lag significantly compared to what’s possible in developer experience.
- Video generation: For the last few days, I have been experimenting with automated video generation for the project's social handles. I'm still struggling with the right hooks that reduce the skip rates, but it's fun.

Additionally, working on an Apple Watch app similar to my Mac app on the same lines, [Plug That In](https://plugthat.in), i.e., notify before the device goes too low on battery, but with a twist.
https://leftium.github.io/nimble.css
I made a classless CSS library, then migrated most of my projects from PicoCSS.
I also made a quick logo generator: https://logo.leftium.com/logo
I'm building a debate/writing game platform: https:argyu.fun
The mission is to incentivize better thinking. For each game there's an AI judge that scores everyone's answer based on a public rubric (style, cohesion, logic, etc).
Currently uses fake money and ELO score but thought it could be a very interesting competitive game for real stakes.
Any feedback is much appreciated.
Bare bones IM program inspired by bitmessage(.org): https://github.com/iljah/p2pIM Uses proof of work for spam protection. Consists of server and command line client written in python.
I am working on building Bloomberry, an alternative to Builtwith for finding companies thar use a specific SaaS product.
Example: Companies that use Github: https://bloomberry.com/data/github-enterprise/
I wanted to make JSON/YAML configuration language for my projects. And i wanted a strict specification. This is want i created, now with specification and 100% coverage, reference implementation it’s just one prompt to reimplement parser in another language.
I built an Android app for nurse-midwives in Zanzibar to get medical advice. It's running Gemma 4 model on device, completely offline. I just released the first beta version. Feedbacks are welcome :)
A complex text shaping and rendering library in Javascript and no_std Rust that supports Ligatures, Bidi, Arabic, indic, CJK, Khmer, etc and is super small and memory efficient. JS version is <25 KB gripped, Rust version is aimed at approx. 130 KB compiled size. My plan is to show a demo of it running on an esp32 soon.
Not working on it yet but planning some projects with the kids: - A candy classifier with Arduino for Halloween (the goal is to have trick-or-treaters choose their preferred candy and have the machine sift it out automatically) - A board game based on the idea of fog-of-war, details undecided - An app to reduce screen time
I've been working on Mixreel, a video/motion graphics editor with integrated support for 3D visualization. I'm working with some business clients to produce instructional videos for construction, industrial fabrications, etc.
Inspired by Ralph loop and bash scripts, I created my own version of it where I focus on finding code issues and auditing my codebase. It runs N iterations after mapping the whole code.
https://github.com/BVCampos/operator
It has been working quite well.
Making rent as an open source developer.
Shamelessly trying to attract new monthly sponsors and people willing to buy me the occasional pizza with my crap HTML skills.
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...)
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.
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 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'm building this mostly to scratch my own itch
It's a newsfeed constructed from 130k substack RSS feeds but limited to the past 24h.
Its helping me discover writers other than just what the algorithm gives me.

First post after lurking for.. 15 years.
I've been working towards a new platform that mixes fantasy sports with stock market mechanics. My first public project, I just launched a few week ago. No gambling, free to play (despite the .bet):
2 products released (merge conflicts/codeowners) and now working on workflow automation. Basically trying to use Cloudflare Workers for a different paradigm of executing workflows instead of the traditional n8n VM.
https://lore.kernel.org/linux-security-module/adjwZAevNaDgui...
Patch for linux kernel adding support for enforcing Landlock rulesets from eBPF. In RFC stage now.
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!
I'm building https://personalfinanceisboring.com (PFIB) to help people like me who accidentally made personal finance an obsessive hobby, and would like to return to other hobbies and better uses of their time.
An open pricing framework for quant finance based on QuantLib:
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!
hivemunk (hivemunk.com): hive management for beekeepers.
Data engineer, 20 yrs software / 10 in ag-tech. Picked up beekeeping and was surprised how much structured data a single inspection produces, and how nowhere useful exists to put it. It's a gloved, veiled, honey-and-propolis-covered activity. Tapping through a mobile UI mid-inspection is not ideal, and good luck getting your phone back clean.
The core is a virtual hive model. It's all mutable state: boxes, frames, components, queens, and colonies you rearrange to mirror the physical yard. Treatments, feedings, and inspections layer on top.
This summer I'm shipping voice-driven inspections: narrate what you see frame by frame, STT + LLM pipeline extracts structured data and maps it to your hive model.
If you have beekeeping friends, I'd love it if you could send it along <3. I won't claim it has every feature under the sun, but I work on it every day and have a strong roadmap ahead.
Also open to critiques. Thanks!
An alternate ad network (tied to an ad blocker) that optimizes for the most useful ads instead of the most immediately profitable ones. https://github.com/Chrisjayhenningsen/Eudaimonia
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.
Self-hostable slack for humans and openclaws - iphone, mac, web, and soon android. Very important for me to get close to feature parity with team chat apps. https://github.com/bogpad/meepachat
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!
