Why captioned lecture video matters

Captions support deaf and hard-of-hearing students, English-language learners following along in a second language, and simply make recorded lectures more usable for review.

♿

Accessibility for students

Supports students who are deaf, hard of hearing, or benefit from reading along with spoken content.

🌍

Language learners

Captions (or translated captions) help students following coursework in a non-native language.

🔒

No student data uploaded

Classroom recordings, which can contain student voices/questions, stay on your own machine.

A note on accessibility compliance

CaptionLab generates accurate, timed captions of spoken content, which is the core requirement in most institutional accessibility policies. It doesn't independently guarantee compliance with a specific standard (like WCAG or a particular institution's accessibility policy) — check your institution's specific requirements, and review generated captions before relying on them for compliance purposes.

Frequently asked questions

Is this a substitute for professional closed-captioning services required by law in some contexts?
For legally mandated accessibility compliance (e.g., ADA in some US contexts), check your institution's specific requirements — CaptionLab produces accurate captions but isn't itself a certified compliance service.
Can it caption a full semester's worth of lecture recordings?
Yes, though each lecture is processed individually per clip/sequence — there's no dedicated batch queue for processing an entire semester's videos unattended in the current version.
Does it work for lectures given in languages other than English?
Yes, in any of the 99 languages Whisper supports.
