If you searched for a website that turns lectures into notes, you can do that in the browser today: open app.lecha.app, add the lecture (audio, a YouTube link, a PDF, or an image), and get notes, a transcript, quizzes, and flashcards. If you are sitting in the room, the iPhone / iPad app is the recorder. Neither one raises a grade by itself.
The older version of this page said a web version was “on its way.” That is stale. As of 21 Aug 2026, lecha.app lists the web app and the App Store listing (iOS 16+ / iPadOS 16+) describes recording lectures and transcribing voice notes into formatted digital lecture notes.
Key takeaways
“Website” here means the live web app at app.lecha.app, not a promise of a future desktop site.
A transcript is the full-text record. Lecture notes are the formatted page. Quizzes and flashcards are the study method.
Phone recording is for the room. The website is for files and links you already have.
Ask before you record. Do not open this in a closed-book exam.
This URL stays
the-best-website-that-turns-lectures-into-notes. The title dropped “best” because that was unsourced.
What does a website that turns lectures into notes actually do?
It takes a lecture-shaped input and returns a notes page you can revise from.
On lecha.app that input can be audio, a PDF, video, or images. Output is notes, transcripts, quizzes, and flashcards. A YouTube link is the homepage-stated “under 60s” path; that timing is a homepage claim, not an independent benchmark. See YouTube video notes.
If you only re-read the new page, you are 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.
When should you use the website vs the phone?
You have | Use | Don’t use |
|---|---|---|
A file, PDF, or YouTube link at a laptop | A second “coming soon” wait | |
A live lecture you are allowed to record | iPhone or iPad recorder (App Store) | A laptop mic from the back row unless you have already tested it |
A problem-set question the transcript does not unpack | Photo Tutor (photograph the question) | Pasting the walkthrough as submitted work |

How do you turn a lecture into notes on the web?
Check whether the lecture may be recorded or uploaded (department policy, copyright on the video).
Open app.lecha.app in a browser.
Add the lecture: audio, PDF, video, image, or a YouTube link if that is what you have.
Use the transcript for wording you need to quote or check. Use the notes page for revision.
Generate quizzes or flashcards the same day. Do not only highlight the new document.
How do you do the same thing from a live lecture?
Ask whether recording is allowed.
Record in the iPhone or iPad app. The App Store copy (21 Aug 2026) describes recording and transcribing voice notes into formatted digital lecture notes.
After class, treat the notes as source material for a quiz, not as a document to reread once.
If the problem set does not match the wording in the transcript, use Photo Tutor on a photographed question. Steps, not an answer key. Details: the lecture-transcription guide.
Not for you
You need Android. Lecha is iPhone, iPad, and web as listed 21 Aug 2026.
You wanted a ranked “best website” roundup. This page is a how-to for one shipped product, not a scored comparison.
Your course forbids recording or uploading the lecture.
The assessment is closed-book, invigilated, or bans AI / outside help.
You only wanted a prettier file to highlight.
