Perfect for teachers & educators

Lecture video captions serve multiple purposes. They make your content accessible to hearing-impaired students, help ESL learners follow along, and improve engagement because students can read while listening. Captioned lectures also become searchable — students can find the exact moment in a recording where a concept was explained.

CaptionFit handles the technical work automatically. Upload your Zoom lecture recording, Loom screen capture, or smartphone video. Paste your lecture notes to fix subject-specific terms the transcription might miss, then export an SRT or captioned MP4 for your learning management system.

If you create structured online courses beyond classroom recordings, also see how course creators add captions to e-learning videos. And if you do academic research, explore how researchers use CaptionFit for audio transcription.
