Listen now, study later
The problem with note-taking in a lecture is that the act of writing pulls your attention off the explanation. A lecture note taker flips that: it captures everything, so you can follow the argument and review the structured version afterward.
How Cloak handles a lecture
Cloak captures audio — from your laptop playing a recorded lecture, a video call, or a room mic — and runs live speech-to-text into a rolling transcript. When the session ends, it produces structured notes: the main topics, key points, definitions, and open questions worth following up.
Ask while you learn
Because Cloak is a copilot, you can ask it to clarify a concept the lecturer raced through, or to summarize the last ten minutes if you zoned out — answers appear in an overlay, grounded in the transcript so far.
Yours, on your machine
Transcripts and notes stay local. Only the prompts you send reach your chosen AI provider (your own key, or a managed plan). Your study material isn't uploaded to anyone's cloud by default.
