Show HN: TimeBrain – Self-Hosted AI Activity Tracker

2 cristinon 0 8/15/2025, 4:04:16 PM timebrain.io ↗

Free. Self-Hosted. Open Source Collectors. Bring Your Own LLM.

I built TimeBrain since I wasn't satisfied with existing activity trackers. I wanted to understand what I spent my day working on, while remaining in control of my data, and without spending hours trying to decipher crowded graphs.

You can try the demo with test data: https://demo.timebrain.io If you are interested in participating in the beta I will be releasing invite codes to download the full version on the Discord, which you can find on the site.

Please let me know any feedback or your opinions on my product :)
