Before you pick an AI note taker, check five things: how it captures lectures, which files it accepts, whether it turns notes into quizzes or flashcards, which OS it runs on, and whether your course allows recording or outside help. In Lecha that means record on iPhone or iPad, or add audio, a PDF, video, an image, or a YouTube link at app.lecha.app. You get notes, a transcript, quizzes, and flashcards. It is not a grade machine, and it is not for closed-book exams.
This URL used to read like a sourced competitor review. It was not. Unsourced Coconote / TurboLearn takedowns, invented “almost double” / “half the price” claims, and fake student quotes (Sarah, Jake) are withdrawn. The slug stays; the title and body do not. GSC (28d to 18 Aug 2026): 30 impressions, 0 clicks, average position about 7.9. The App Store listing (21 Aug 2026) covers iPhone and iPad, iOS 16.0+ / iPadOS 16.0+.
Key takeaways
Capture alone is not enough. Ask whether the tool also builds quizzes or flashcards you can practice from.
Verify OS and inputs on the vendor’s site. Do not trust a blog that invents prices or competitor scores.
Check exam and recording policy before you hit record.
Photo Tutor is step-by-step guidance on a photographed question, not an answer you submit.

What should you check before you trust an AI note taker?
Check | Why it matters | Lecha (from product truth) | Anything else |
|---|---|---|---|
Capture | Live lecture vs files/links | iPhone/iPad recorder; web for files/links | Check their site |
Files / inputs | Audio, PDF, video, images, YouTube | Audio, PDFs, video, images → notes, transcripts, quizzes, flashcards; YouTube link supported (“under 60s” is a homepage claim only) | Check their site |
Retrieval practice | Notes you only reread still fail Dunlosky’s low-utility list | Quizzes and flashcards from the same session | Check their site |
OS | Phone in the room vs laptop for files | iPhone/iPad, iOS 16.0+ / iPadOS 16.0+; web at app.lecha.app; Android not shipped | Check their site |
Exam / course policy | Recording bans and closed-book rules | Not an exam device; ask before you record or upload | Follow your syllabus |
Dunlosky, Rawson, Marsh, Nathan and Willingham (2013) rated practice testing high-utility and rereading low-utility (journal article). That paper does not evaluate Lecha.
How do you run that checklist without inventing a “review”?
Write down the lecture formats you actually have (live room, PDF slides, YouTube, image of a problem).
Confirm the app’s OS and inputs on the App Store or vendor site — not from an unsourced blog table.
Ask whether notes can become quizzes or flashcards the same day.
Read your syllabus for recording and AI / outside-help rules.
Ignore grade promises, fake testimonials, and price claims you did not verify yourself. This page used to include those; they are gone.
For PDFs specifically: How to turn a PDF into notes, quizzes, and flashcards. For the lecture path: How to turn a lecture into notes and retrieval practice and How to transcribe a lecture, get notes, and use Photo Tutor. Website vs phone: A website that turns lectures into notes.
Where does Lecha fit that checklist?
Lecha ships capture plus retrieval on iPhone, iPad, and web. Record a lecture you are allowed to record, or upload audio, a PDF, video, or an image. Paste a YouTube link when that is allowed. Use the transcript to check wording; use quizzes and flashcards to practice. Photo Tutor takes a photo of a question and returns step-by-step guidance — practice and permitted homework only, not an exam shortcut.
Not for you
You wanted a sourced multi-app price / feature shootout. This page will not invent one.
You need Android.
Your course forbids recording or uploads.
The exam is closed-book or bans AI / outside help.
You wanted Photo Tutor to finish and submit the problem set for you.
You only wanted prettier notes to highlight and reread.
You wanted a grade guarantee or “boost your grades” promise.

FAQ
Is this page still an AI note takers review?
No. The old page unsourced-compared other apps and invented prices and quotes. That framing is withdrawn. This rewrite is a checklist plus an honest Lecha fit.
What should I check in any AI note taker?
Capture method, supported files, quizzes/flashcards, OS, and exam policy. Use the table above. For competitors, check their site — do not trust invented numbers.
Does Lecha work as an AI note taker?
Yes. Record on iPhone or iPad, or upload lecture-shaped files on web or iOS. You get notes, a transcript, quizzes, and flashcards. Details: What an AI note taker does in Lecha.
Will this boost my grades?
No. Quizzes and flashcards are retrieval practice. They do not sit the paper or raise a grade by themselves.
Is Photo Tutor a homework solution generator?
No. It is step-by-step guidance on a photographed question. Use it on practice and permitted work. Do not treat the guidance as submitted work.
Is there a free trial?
The homepage calls out a free trial. Check the current offer. This article does not state a length.
Does it run on iPad?
Yes. App Store listing 21 Aug 2026: iPhone and iPad, iOS 16.0+ / iPadOS 16.0+. Also app.lecha.app.
