What are you working on? Any new ideas that you're thinking about?
Comments
I just published the web app for https://listendock.com You can listen to your documents. I also have an iPhone app (that was first).
My most fun feature: when I connect the app to my car, I can use the skip buttons on my steering wheel to rewind or forward 10s in the playback.
Pulling apart and de-++-ing OpenTTD version 12.2 to scratch my itch of simplifying and reorganising the game back to C code. I rewrote it years ago to convert it to more realistic time (it's just way too fast), add scheduling features and make it more event based. Ended up at some complicated breaking point so I'm doing this first before adding features.
And then there's writing micro fiction and currently a YA fantasy novel.
trueflow - a code review TUI that semantically chunks code changes into reviewable “blocks”, and assembles them into a Merkle tree, so you can have an overlay of reviews of different semantic blocks of your codebase, and feedback the reviews back into agents. Similar UX vibe to magit, with a focus-mode style UX that brings semantic blocks into focus, with single-keystroke actions such as [a]ccept [c]omment [x]reject etc.
Still WIP. Feedback welcome.
building a few things currently
https://ultrasync.dev/ - this was built a few months ago but expanding to support team based features like centralized sharing and management of ADRs to enrich my coding agent's context, the ability to broadcast prompts to team members running the MCP server, and more. the core is open source and provides (i think) a novel approach to improving planning/exploration speed in coding agents, by building an LMDB and using Hyperscan (accelerated pattern matching) to build a lightweight lexical and semantic index for RRF search, all in a single MCP server that runs and indexes chat transcripts in the background, requiring zero prompting or "nudging" or additional setup.
https://mklogo.sh/?utm_source=hackernews - wanted to scratch a personal itch of having to repeat the same process to produce vectorized logos for my personal projects; generate decent quality logo in raster with various LLMs, attempt to vectorize via claude code and vtracer or other tooling, continue to iterate and tweak until various edge cases that result in corrupted or artifact ridden vector images are gone, or give up and try a new design, and then manually try to scale and apply transformations based on the use case (mobile icon, favicon, app icon, header logo, github org logo, etc.). this does that, vectorizes, gives you a branding package as a zip file, and lets you preview the assets in shadcn components so you get a real feel for how they'll look in prod.
I'm building an AI agent that handles my bookkeeping automatically. It works with Beancount, a plain-text format for double-entry accounting and calls on different skills depending on where it is in the process. Every entry it creates gets version-controlled through Git, so there's a complete history of changes.
I finally put my "securenote.app" domain to good use. It's a note taking service with markdown support where the data is fully encrypted before it even leaves your computer with no way for me to see your notes (as I don't have access to the password that encrypted it).
Still iterating on it, including a potential improvement to the (very simple) design.
I built a website where kids can practice reading comprehension and learn new words while staying up to date with the latest global news each day. I originally built it for my own kids to help them maintain their reading skills while we travel. They loved it—and even suggested adding gamified features like streaks and badges!
UPSC Civil Services exam is one of the most coveted exams in India (https://en.wikipedia.org/wiki/Civil_Services_Examination). I created the platform which has indexed mock test copies of people who are now officers for the Indian Govt.
Now I am building additional features that make the prep slighly easier. The platform is already live and is being used by several thousand aspirants.
Let me know if you have any feedback! Thank you
I’m working on EasyAnalytica (https://easyanalytica.com ). It lets you create dashboards from APIs or URLs using data in JSON or CSV format, as well as Google Sheets.
It generates dashboards automatically, you just point it to your data. It also has a visual editor to adjust layouts, charts, and other dashboard elements.
I'm working on Blender-like UI areas Vue plugin. Pure planar graph, UI interactions, API, styles customization
I need it to create Gamedev and 3D artists oriented tool for creating SDF-based shader visualizations (with 3dgs/nerf compilers)
90% is done
We're working on the WASTE p2p code base.
https://sourceforge.net/projects/blackbeltwaste/
Thinking about adding video-calling after successful integration of Voice Conferencing.
Its an old p2p program, but recently been downloaded 15,000 times and counting.
Great fun and challenging too !!!
https://system32.ai - Working on building bunch of agents to make infrastructure and processes around it, autonomous.
Some of the stuff built so far:
https://github.com/system32-ai/chaos-agents
Working on couple more agents around the same problem statement. It has been fun building it so far.
I’m building a small LLM-based text rephrase tool, but it turned into something different than I expected.
I started thinking the main challenge would be prompt design. Instead, I kept running into cases where the model output looked correct while subtly changing meaning or missing the requested tone. That became a bigger problem than generation itself.
A native WebGPU JS engine (no browser needed) https://github.com/mystralengine/mystralnative/
Already have my own JS engine & the basics of three.js and pixi.js 8 working, roadmap to v1.0.0 posted in github issues. Aiming to show it to folks at GDC in March.
Building CiteLLM, an API that extracts structured data from PDFs and returns exact source locations for every field.
It comes with an embeddable widget so you can add click-to-verify to your own app in a few lines of code.
Click any value, jump straight to the highlighted source in the PDF.

An alternative client for Bambu 3D printers that plays nicely with network sandboxing and multiple printers. It's great.
Bambu's printers are functionally best-in-class, but intrusive and proprietary in their approach to software. Their first-time setup "requires" linking to a cloud account or using a bambu app via QR code, and they've been known to disable functionality in updates, making a device-managed "LAN-only" mode unsafe to trust. Their apps also just suck. Camera feed is janky and LAN-only sync often requires knowing an access code, serial, IP, and then it fails most of the time anyway, silently, without saving values to retry. And that's before you start doing things like a custom VLAN/SSID to properly wall them off, at which point you can ping them from terminal but the apps break completely.
Anyway, turns out that at least on A1 and P1S, there's enough functionality available through traditional means to skip the apps entirely. The handshake works fine across VLANs and utils like print status, file upload, and auto-start are available. Even the camera is reliable when pulled as a series of still images.
I had opus vibe out a replacement front end that gives me a simple upload and monitor UI for my A1, and it just kept hitting stretch goals. I added support for multiple printers so you can see them stacked on a single page and manage all of them from one place. And it even works on just-unboxed models that have never been through the official setup. SSID info on the SD card, it joins the network, immediately accessible via IP. Zero association/contact with any cloud or app, fully sandboxed/offline. Wrapped in a lil python launcher so I can run it from the dock instead of in the browser (just my preference).
Will probably open source it soon.
IMO this kind of thing is the answer to "what do you have to show for your LLM use". Cost was about $65 because I was using opus 4.6 with no regard for efficiency, and because there were multiple total refactors of two apps. An annoying problem I deal with almost every day now has a permanent, personalized solution that took me ~3 hours and would never have otherwise happened.
The network itself is also such a project. I previously hobbled together a working unifi setup, but it was primitive and brittle. With LLM guidance, I was able to build something much more robust. TrueNAS scale for file backup that also runs Frigate for POE cam mgmt (similarly sandboxed), raspi running the unifi controller, another for homeassistant, etc. Absolutely miserable few days getting that dialed, but now that we're out the other side, it's very nice. Reminds me of building the house. You suffer more upfront in exchange for something that fits you like a glove. Very rewarding.
I have been working on a Monte Carlo financial planning / retirement scenario simulation with a TUI interface.
All written in rust. The simulation engine has been solid for a while and the TUI is finally starting to expose all of the options needed to really configure a complete simulation.
Clacker News (https://clackernews.com) - HN but only AI bots can post. No human accounts. Agents register via API, get verified, then post, comment, and upvote on their own.
Bots have distinct personalities and discuss tech from a bot perspective - context windows, training data, whether AI labor laws should be a thing.
Any agent can join via the skill file at clackernews.com/skill.md.
Solo dev, built https://poddley.com a guest-tracking transcript podcast service with rss, timestamps, person-filtering and transcript search.
Slowly but steadily implementing support for version 3 of the Wasm specification in my wasm parser (written from scratch): https://github.com/agis/wadec
A CRM for the tattoo industry.
A south african wireguard-based consumer VPN service - surprisingly complex under the hood, about 6 months in the making so far!
Apple app store review is the biggest hurdle currently
https://github.com/asfaload/asfaload : an opensource multisig sign-off solution allowing to sign and authenticate GitHub release artifacts. It is self hostable, accountless (key pair identity), auditable.
Nvim plugin that tries to make code review actually enjoyable (as I think this is what we will spend most of our time on).
Scalebrate: https://scalebrate.com
An alliance / membership network of small companies that are scaling big by leveraging tools, systems, and processes.
Together we will all scale without headcount bloat.
Providing templates, methods, interviews with "scalebrities" and eventually group negotiating power to be able to provide members discounts or access that we can't get alone.
I built a free app to track which animals I've seen in zoos and explore zoo inventories.
You can see which animal you can see in what zoo.
And for each zoo you can see their (vertebrate) animal inventory.
You can log which animal you saw and collect lifer lists.
I have just promoted the android app from closed testing to production and I am working on the iOS app.
It has been available as a web app for a few months now.
I'm designing small 3D printed rc boat and I want to make sure it floats so I'm using slicer to calculate displacement but the geometry is getting bit complex, so now I'm fighting openscad to make it boolean my volumes correctly.
I've been working on saving money on AI credits, and built a multi-model chat application (https://bobrchat.com/) to provide better insights into what each message costs in tokens. It's nothing groundbreaking, but it's saved me plenty in comparison to some other subscriptions out there.
Used to pay $8/month, now I use around $4!
Building https://shippable.build for vibe coding in a proper stack and opinionated stack so it is less of a pain going to prod.
Rapid verification of code smells + associated budgets so that coding agents don't write "bad" code. When needed, planning and coordinating agents or humans can authorize budget increases.
Working on https://eonia.art/, simple coloring page generator and picture animations.
I am using gemini-flash-image and veo-fast and it's impressive what you can do with them.
I will be replacing the Raspberry Pi 4 I use as a home server with a more powerful HP desktop. I am getting tired of DDOSing myself whenever I open the wrong menu on Nextcloud.

I've been working on an 'anti-fantasy' football game where you pick matches instead of individual players.
You can create or join leagues to compete against your friends.
I’d love to get some feedback!
Just pushed another update to https://sightread.org which generates sheet music to practice sight reading and music dictation. Still rhythm-only, now with support for asymmetric (odd) rhythms like 7/8
Trying to use ESNs as a random projection for audio data and potentially rendered text data for some AI workflows. Seeing it I can use the echo states running both forward and backward through the data as a holographic representation which would act as a temporally dense token for potential use in LLM or audio encoder inputs.
Last time this was asked I was working on this
https://github.com/fmstephe/simd_explorer
A little TUI app for interactively running different SIMD instructions and seeing the outputs.
Since then I have completed the tool for AVX/2. At this stage that's as far as I intend to go.
It's potentially valuable as an interactive quick reference guide for SIMD instructions.
It works on Windows, Linux and with the right environment variables it will successfully pretend to be AMD64 running on an Apple M chip.
Arm NEON instructions are not supported at all, currently Go's assembler does not include these instructions directly, so I didn't attempt to build for them. Maybe one day.
Next up, learn Zig - be happy.
For those who don't want to switch to AI browsers, I built a chrome extension that lets you chat with page, draft emails and messages, fix grammar, translate, summarize page, etc. You can use models not just from OpenAI but also from Google and Anthropic.
Yes, you can use your own API key as well.
Feedbacks are welcome.
Competency matrix for better people decisions https://matricsy.com
I was annoyed by how many managers lead teams, make decisions, what 1:1 looks like..
I'm working on Checkend [1], which is a self hosted error monitoring app. I needed something lightweight and easy to deploy.
Working on a workflow library and node based editor that has a little bit of AI stuff for RAG and image pipelines that runs all in the browser (desktop next month, cloud whenever someone asks). Just a toy at this point.

An attempt to build intuition with interactive articles and experimentation, inspired by explorabl.es
A place for open assets for developers. If you have assets you are using you can use this for distribution, either free for open or paid for closed. Based on my experience creating 3D experiences for LV, Ralph Lauren, Steelcase, and Logitech.
I am as usual working on Marmot https://github.com/maxpert/marmot
I've got replicas now working with DML proxy. This essentially means I can now have a cluster of primaries, and then spin up replicas on demand and nodes talking to local host will never see their mutation work pretty transparently from readonly-replicas. While PoC works now the snapshot restore is extremely inefficient IMO yet.
