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.

Patroclito_class is a free, lightweight Python application designed to extract and save Live Captions from Windows 11 lectures for easier studying and note-taking. The tool captures the on-screen text along with timestamps and stores it in a .txt file, running in the background without interfering with other windows. Users can set a time limit or choose an exact time to stop the recording.
Numbers and symbols are preserved during the extraction process, ensuring accurate transcription. The app requires minimal CPU usage as speech recognition is handled by Windows itself.
To improve the study workflow, the extracted text can be cleaned and formatted as markdown (.md) files, ready to be shared with AI tools for further analysis. The application is privacy-focused, as all data remains local, with no server connection, account creation, or telemetry involved. The creator, Patric Melorr Lang, proposes the tool for students and welcomes feedback on potential improvements.
Patroclito_class was showcased at the Nuevas Fronteras 2026 hackathon, where it secured the second place award. A ready-to-run .exe file is available for download from the project's GitHub repository (MIT license).
