Record the lecture, upload it, and get an accurate transcript you can turn into study notes and search later. Around 100 languages, no account, no daily cap, no watermark.
Transcribe audio now →Re-listening to a whole lecture to find one point is slow. A transcript lets you skim, search for a term, and turn the key parts into notes and flashcards. It's also a big help if the lecturer spoke fast or in your second language.
A clear recording from near the front transcribes well; a faint recording from the back row is harder for any tool. Technical terms are worth a quick proofread. See audio to text for the general flow and how accurate it is. Always record with permission.
A transcript is not notes. It's a 15,000-word document that contains your notes somewhere inside it, and if you stop at the transcript you've moved the problem rather than solved it. The step that makes the difference takes about twenty minutes per lecture and turns reading into remembering.
Work through the text once and pull out only three things: the claims (what is being asserted), the definitions (any term the lecturer bothered to define is a term that appears on an exam), and the examples the lecturer chose, because those are what you'll be asked to apply. Everything else — the admin, the digressions, the repeated explanations — can go. Rewriting a claim in your own words is the part that does the learning; copying it does almost nothing.
The timestamps are what make this fast rather than tedious. Download the SRT alongside the plain text and every line carries the moment it was said, so when a passage makes no sense on the page you can go straight to it in the recording instead of hunting. The click-to-play transcript on the results page does the same thing without leaving the browser: click a line, hear that moment. Use it on the two or three passages per lecture where the lecturer said something that clearly mattered and you didn't follow it, since that's where re-listening actually pays.
One more use worth knowing: a text transcript is searchable across an entire term. Keep them in one folder and searching for a concept will tell you every lecture that touched it, which is the single most useful thing you can have a week before an exam.
Accuracy is decided before you upload anything, and lecture halls are genuinely hostile: a distant speaker, hard parallel surfaces, ventilation noise and 200 people shifting in their seats. The good news is that the fixes are free.
Distance beats everything. Every metre closer to the lecturer helps more than any setting on your phone. Sitting in the first few rows will do more for your transcript than any amount of processing afterwards. Point the phone at the speaker, not at your notebook, and leave it flat on the desk rather than in a bag or pocket, since fabric muffles speech far more than it muffles noise. If your device has a "voice memo" or mono speech mode, use it: it's tuned for exactly this.
Watch the length. ScribeGrab handles files up to 90 minutes each, which covers most single lectures but not a three-hour block or a full seminar day. If your recording is longer, split it in a free audio editor and upload the halves separately; there's no daily cap, so two uploads cost nothing extra. Splitting on a natural break also gives you two shorter documents, which are easier to work through than one enormous one.
Expect trouble in predictable places. Technical vocabulary and names are the main casualties, especially in maths, medicine and law: fix them once with find-and-replace and the rest reads cleanly. Questions shouted from the back of the hall often come out garbled, and there's no fix for that beyond noting the timestamp. If the lecturer speaks a language other than the slides, transcribe first and translate second; language detection is automatic across around 100 languages, but it works on what was actually spoken.
Finally, the boring but important part: check your institution's rules before you record. Most universities allow recording lectures for personal study and many publish their own recordings anyway, but permission is usually tied to personal use, and sharing or uploading a recording is a different question from making one.
Yes. Up to 90 minutes and 2 GB per file, with no daily cap and no watermark.
Mostly, but proofread specialised vocabulary and names, which are hard for every transcriber.
About 100 languages are auto-detected, so most lectures work without changing any settings.
Yes. Record with permission, then upload the file whenever you like; there's no rush and no daily cap.
