What are you working on? Any new ideas that you're thinking about?
Comments
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 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.
Two things, one is a container control plane inspired in the efforts of the Nextcloud AIO people called LOOM (yeah, like the Lucas Arts game), the other is a full blow NixOS deployment system (from the USB or network directly) for my company so we can deploy the computers for each colleague faster.
I built a local tool that uses ollama to transcribe my handwritten journal pages into obsidian pages.

Porting a giant monolithic JSF app from JSF/Wildfly to two separate apps, a react frontend and a REST Quarkus backend.
First time doing this sort of thing with agents. So far it seems ok?
If it works out it will really help us scale and improve a legacy application that so many depend on at the moment. Wish me luck!
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.
Same thing we work on every night, pinky
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.
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.

We are working on making agentic ads and regulatory compliance scalable.
Just launched the blog too
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- make it reliable to run LLM inference on company hardware, even when it is poor or outdated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
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
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.
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.
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.
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.

It runs code locally (written in Swift), includes examples, and has a Turbo Pascal–style theme for max nostalgia.
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'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)

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.

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'm just wrapping up a macOS app to do perspective correction of images. It has a bunch of unique features, easy user interface along the lines of Numbers/Pages/Keynote, and a download size of only 1.1 MB.
with the advent of modern LLM's, I was building a lot of small, shareable, static sites.
Games, utilities, calcultors (for whatever niche), and anything else where I wanted it accessible for me from anywhere, plus the poeple I want to share with (publicly or privately)..
So, I built this:
Simple static site hosting. Upload html or a zip-containing-html along with other needed files, and it gets hosted on a subdomain with full https. Optionally, password protect it, or generate shareable links. Also, detailed analytics and other stuff.
Im already hosting 16 small sites on it.. loving it.
