Hey HN!I wanted a time tracker accurate enough to be useful and easy enough to not require a new habit while protecting your privacy.Most trackers (RescueTime etc) only use activity logs and that isn t enough to be very useful. DoneThat uses LLMs to parse your screenshots, which makes it much more accurate but also requires much higher privacy standards, so let s start with those:- Source-available desktop app (https://github.com/donethatai/donethat-electron) screenshots every few min. - App exclusions (password managers, personal comms, etc.) are blanked before the screenshot leaves your machine. - The rest goes to an LLM (BYO possible) for a short text description, and the raw screenshot is discarded immediately. - That data then gets further processed on GCP (EU) for analyses, sharing, or agentic stuff. - Sharing is opt-in and only possible at an aggregation level that balances privacy and usefulness. You can also limit to relative data. - Data flow visualization more privacy features: https://donethat.ai/data. - Not fully local. If that s a hard requirement, look at Dayflow or Screenpipe (just changed their licensing). I made a list of tools in this space here: https://donethat.ai/compare.Currently working on a proactive Clippy-like coach because it s the highest-requested feature (mostly from self-identifying ADHD folk). Surprisingly hard to make this actually useful and not just gimmicky or annoying.Give it a try: https://donethat.ai
