Useful tools shouldn’t always come with a checkout page attached. And, I have a hard time leaving an interesting problem alone. So, naturally, I spend some of my free time building and contributing to open source software.
From Chrome extensions to community platforms, I pour 20+ years of building products, growing communities and developing businesses into tools people can use, improve and make their own.
Challenge My AI
Challenge My AI lets other people point their Agents at the same question. Weak reasoning gets challenged. Useful critiques improve the answer instead of disappearing inside another private chat.
It works today. The roadmap is public. It is not finished.
Local Community Platform
Local Community Platform gives posts, resources, people, events and votes a place you can search later. Braga AI Builders runs on its own deployment.
One core platform. Each community can shape its own version.
Not every useful idea needs to become a company. Sometimes the problem needs one small tool.
Media Downloader
Media Downloader spots video and audio in Chrome, Brave or Edge, then sends the job to yt-dlp on your own machine. No sketchy converter site. No uploading the file somewhere else.
Signal to Noise Ratio
Signal to Noise Ratio shows the percentage of browsing that moved your work forward and the percentage lost to distraction. Your data stays in Chrome.
Paws Platform
Paws Platform gives them dog listings, profiles, adoption information, donations and an admin panel they can fork and run. The same code powers CAPA’s public site in Portugal.
YouTube Saver
YouTube Saver turns the pile into bookmarks and closes the tabs in one click. That is it. It does not need to be a startup.
I use Hermes Agent every day. When it breaks under real work, I report the bug, fix what I can and send the change back. Nous Research owns the project. My fork is public.
Building something worth talking about? Let’s talk!
