Never1 track your time manually again.
Tesseract captures your screen activity locally and gives your AI the context to fill in your timesheet.
1 Well, “never” is probably a bit of a stretch.
But if you're like me, you've struggled your whole life to turn on timers, keep careful journals, and build a habit of tracking your attention in the moment — only to end up disappointed and frustrated every time.
What if you could just ask your computer what you did?
Not all work happens on your Mac. And reviewing timesheets still feels like a vital part of our professional work. But wouldn't it be great if most of what we did was reviewing, instead of stressing about tracking?
Lately, AI has let me offload a huge part of what gets in the way of my flow. I made Tesseract to support that.
Hope you like it. Drop me a line — I'd love to hear what you think.

How it works
Start it
Tesseract runs discreetly in your menu bar until you pause it, or quit it.
It pays attention
It watches what you pay attention to, and captures your foreground window to a little nugget of memory. All this happens locally on your Mac.
Connect your AI
Connect ProofChat, Claude, or some other AI to Tesseract and watch the magic happen. Search your past activities, summarize your day, prepare a timesheet.
Why it's different
Privacy first
Your privacy and safety comes first. Tesseract runs locally and doesn't use those darn big computers in the sky to process your captures. It's your memory.
Low footprint
Tesseract is designed to be lightweight and gentle on CPU and memory.
Zero effort
No tagging, no clipping, no timers. Your history builds itself.
