An AI note taker turns a lecture-shaped input into a notes page you can revise from. In Lecha that input is a recording, audio file, PDF, video, image, or a YouTube link. The output is notes, a transcript, quizzes, and flashcards. It does not raise a grade by itself, and it is not something to open in a closed-book exam.
This URL used to promise “boost your grades” and call Lecha “the best.” Both were unsourced. The page also said a web version was “on the way.” As of 22 Aug 2026 the web app is live at app.lecha.app. The App Store listing (iPhone and iPad, iOS 16+) describes recording lectures and transcribing voice notes into formatted digital lecture notes.
Key takeaways
Use this page for what the product does, not for a ranked “best AI note taker” list.
Phone recorder is for the room. The website is for files and links. See website that turns lectures into notes.
Photo Tutor is a photographed-question walkthrough, not an answer you submit.
Ask before you record. Do not use this in an assessment that bans outside help.
What can you put into Lecha?
Input | What you get | Don’t expect |
|---|---|---|
Live lecture you may record | Transcript + formatted notes from the iPhone/iPad recorder | A licence to zone out |
Audio, PDF, video, or image on the web | Notes, transcript, quizzes, flashcards at app.lecha.app | Android |
YouTube link | Notes, flashcards, quizzes; “under 60s” is a homepage claim, not a benchmark | A sourced speed test |
A problem-set photo | Step-by-step Photo Tutor guidance | A paper you can paste in as your work |
The in-room sequence is written up here: How to transcribe a lecture, get notes, and use Photo Tutor.
How do you use it as a college note taker?
Check whether recording or uploading the lecture is allowed.
Record on iPhone or iPad, or add the file/link at app.lecha.app.
Use the transcript for wording. Use the notes page for revision.
Generate quizzes or flashcards the same day. Rereading the new page is still rereading. Dunlosky, Rawson, Marsh, Nathan and Willingham (2013) rated rereading low-utility and practice testing high-utility (journal article). That paper does not evaluate Lecha.
If the problem set does not match the transcript, photograph the question in Photo Tutor and cover the next line.

FAQ

On practice and permitted work, as a walkthrough you try to reproduce. Not on a banned assessment, and not as submitted work.
