↓ Watch what comes out
A lecture recording is rarely clean — the lecturer is on a lapel mic, student questions come from 40 feet away, and half the vocabulary is field-specific. We label every turn and pass your syllabus terms to the recognizer.
So the rate-determining step here is the formation of the carbocation intermediate — that's why tertiary substrates react faster in SN1.
Professor, would a polar protic solvent stabilize that intermediate?
Good question. Yes — water or methanol stabilize the carbocation through solvation. That's exam-relevant, by the way.
Is that in chapter seven or chapter eight?
↓ This is the dashboard
Same layout as the real dashboard — Summary, full Transcript, Speakers tab, Exports. Key points and action items extracted automatically. Auto-tags on every job.
Sample preview from a founder interview about post-call workflow. Real transcripts look exactly like this — same tabs, same summary block, same key-points / action-items split, same auto-tag chips.
Three real options · honest comparison
Otter sells a student tier with a live-record app. Handwritten notes are free but lossy. We work with whatever audio you already captured — phone memo, lecture-capture export, or a Panopto download.
Live-record app with classroom mode. EN-only, 30-importing cap on the free tier.
Drop the file. Or paste a Panopto/Echo360 URL. Course vocabulary supported, no subscription required.
Free, but you only capture what you can write while listening. No search, no replay.
Pricing and feature flags accurate as of 2026. Otter free-tier import caps change frequently — verify on otter.ai before assuming.

Accuracy · real-world numbers
The ceiling is set by how the lecturer was miked, not the room. A wired lapel feeding the lecture-capture system is the best case. A phone propped on the desk in row 12 is the worst. Numbers below come from real student uploads.
Direct feed from the lecturer's lapel mic. Minimal reverb, no crowd noise. Student questions still suffer if the room mic is off.
Single lecturer, moderate distance. Field-specific terms are the main error source — paste the syllabus into custom vocabulary.
Reverberant 200-seat room. Lecturer stays clean; student questions from the back may merge into one speaker.
Worst case in our data — non-native English speaker, large lecture hall, board taps masking phonemes. Still usable for review.
