Track your time.
Let AI organize it.
The privacy-first productivity tracker that uses local Machine Learning to understand what you're working on—without ever sending your data to the cloud.
Free forever. Open Core. Available on Windows, Mac, Linux, & Android.
How it works
Stop managing rigid categories. Just type what you're doing, and our local K-Nearest Neighbors AI will figure out where it belongs.
Write
You just type "Debugging the temperature API" and click Start. That's it.
Work
Do your job in peace. The timer runs quietly in the background or in your system tray.
Magic
When you stop, the local AI instantly groups it with your "Backend Refactor" project based on semantic meaning.
