I built a free tool that saves Windows 11 Live Captions so I can study from my lectures

The problem
In class, knowledge fades. I wanted the text of what was actually explained, so I could study from it later — not just from my own notes.
What it does
Patroclito_class is a small Python app that reads the text Live Captions already shows on screen and saves it, with timestamps, into a .txt file. It runs in the background, so other windows can be on top.
- Stop manually, after N minutes, or at an exact time
- Numbers and symbols are preserved
- Very low CPU use (speech recognition is done by Windows itself)
My study workflow
- Record the class
- Clean up the text — even good transcription can have grammar errors, foreign words rendered phonetically, or local expressions
- Save as
.md - Give it to an AI (tagged like HTML) so it has the context of hours of lecture
Privacy
Everything stays local. No server, no account, no telemetry. Whether to ask permission before recording a class is your own responsibility.

It was proposed in my hackathon Nuevas Fronteras 2026 (2nd place — announced by the organizer). I made it for students — feedback welcome. What would you add?
