Record the class. Audio streams to the server for live transcription — nothing to download on your phone.
How it works: your phone records in short segments and sends each one to a Cloudflare Worker, which transcribes it with Whisper and sends the text back. Transcript appears a few seconds behind speech. Data use is small (audio only, roughly half a megabyte per minute) — no 800 MB model download.
Note: audio leaves your phone to Cloudflare's transcription service for processing; nothing is stored there by this app.
