Kryzz AI is a free, MIT-licensed Android app for people who want an AI assistant without another account or subscription. You paste your own OpenRouter key, it uses hosted models (nothing runs on the phone itself), and your chats, memory, files and keys stay on the device. There's no Kryzz server in the middle.
It just went past 200 APK downloads from GitHub releases, all from posting and writing about it, no ads. This week it also got its first signed release build, about 19 MB instead of the old 82 MB debug one.
The honest weak spot is the first five minutes: getting an OpenRouter key is a step a lot of people don't want to do. If you tried it, or decided not to, I'd really like to hear where it lost you.
I make Kryzz AI (free, MIT, Android). You give it a task, it shows a live checklist, does the searching and reading, and hands you a file, for example a spreadsheet comparing three phones with sources.
The thing I keep going back and forth on is trust. Right now it shows the plan first, logs every search and page it read, caps spend per task ($0.25 by default), and stores everything on the phone. Models run through your own OpenRouter key, and the APK is still a debug build. Is that enough, or would you want an approve-each-step mode?
Kryzz AI v1.1 is a personal, MIT-licensed FOSS Android AI workspace built local-first for privacy and control. Download the APK from GitHub Releases and run your workspace on your device.
v1.1.2: Agent Auto live plan through the turn, Fast/Balanced/Max, work log, DOCX/XLSX/PDF outputs, review-before-send, and $0.25 default cost cap. Demo https://youtu.be/RheYy473mRU. MIT, local-first, BYO keys.
