To transcribe a lecture and turn it into lecture notes, record the session on your phone, then generate a transcript and a formatted notes page you can actually revise from. When the homework question doesn't match the wording in that transcript, Photo Tutor is the next step: photograph the question and read the steps as a walkthrough, not as an answer key.
That loop is what Lecha ships today on iPhone, iPad, and the web app: lecture recording, transcription, notes, quizzes, flashcards, and image-based Photo Tutor. It is not a grade machine, and it is not something to open in a closed-book exam.
Key takeaways
A transcript is a record of what was said. Lecture notes are the formatted page. Retrieval (quizzes/flashcards) is the study method.
Lecha's App Store listing (21 Aug 2026) describes an in-app recorder that transcribes voice notes into formatted digital lecture notes. iPhone and iPad, iOS/iPadOS 16.0+.
Photo Tutor is the homework-photo flow on lecha.app: upload or snap a question, get step-by-step guidance.
Practice testing beats rereading. Dunlosky et al. (2013) rated practice testing high-utility and rereading low-utility. That paper does not evaluate Lecha.
Ask before you record. Don't use Photo Tutor in an assessment that bans AI or outside help.
What is the difference between a lecture transcription and lecture notes?
A lecture transcription is the full-text record. Lecture notes are the cleaned, formatted version of that record.
If you only re-read either one, you are still rereading. Dunlosky, Rawson, Marsh, Nathan and Willingham (2013) rated rereading and highlighting as low-utility techniques, and practice testing as high-utility (journal article).
How do you transcribe a lecture in Lecha?
Check whether your department allows recording.
Open Lecha on iPhone or iPad, or use app.lecha.app.
Record the lecture. The App Store copy (21 Aug 2026) describes recording and transcribing voice notes into formatted digital lecture notes.
Use the transcript for exact wording; use the notes page for revision.
Generate quizzes and flashcards after the lecture, as described on lecha.app.
Optional: if the lecture already lives on YouTube, the homepage states that pasting a link returns notes, flashcards and quizzes “in under 60s”. That timing is a homepage-stated claim, not an independent benchmark. See YouTube video notes.
What should you do with the notes after class?
Same day: quiz yourself from that lecture's notes without looking at the transcript. Same week: a short quiz on this lecture plus the previous one (distributed practice). When a worked example still will not unpack, use Photo Tutor.
After class | Do this | Don't do this |
|---|---|---|
Same day | Generate quizzes/flashcards from the notes (lecha.app) | Only re-read the transcript |
Same week | Short quiz on this lecture + last lecture | One long cram |
Stuck on the problem set | Photo Tutor on a photographed question | Paste the walkthrough as your submitted work |

Where does Photo Tutor fit?
Photo Tutor covers the gap a transcript cannot: the problem set.
lecha.app describes Tutor as: stuck on a question, upload an image, get step-by-step guidance. The App Store listing (21 Aug 2026) describes snapping a photo of homework for a step-by-step breakdown.
Attempt the question first.
If stuck, photograph it in Photo Tutor.
Cover the next line and try to produce it (self-explanation).
Close the walkthrough and do a neighbouring problem.
If the steps disagree with the lecture, trust the module's method.
Not for you
You need Android. Lecha is iPhone, iPad, and web as listed 21 Aug 2026.
Your course forbids recording, or you have not asked.
The assessment is closed-book, invigilated, or bans AI/outside help — do not open Photo Tutor there.
You want a tool that submits the working for you. A walkthrough you paste as your solution is passing off someone else's working.
You only wanted a prettier document to highlight. Capture without retrieval is still rereading.
