For Course Creators

Captions for Your Online Course Videos

Udemy and Teachable require captions. CaptionFit transcribes your course videos, lets you paste your script to fix errors, and exports a clean SRT.

How it works

Three steps. That's the whole thing.

  1. Upload — Drop in your course lesson video (MP4 or MOV) from your recording setup.
  2. Transcribe or paste — Auto-transcribe, or paste your lesson script to instantly align and correct terminology.
  3. Download — Export an SRT for Udemy, Teachable, Thinkific, or any e-learning platform that accepts captions.

Perfect for course creators

E-learning platforms now require or strongly recommend captions on all course videos. Udemy uses captions as a quality signal that affects search ranking. Teachable and Thinkific let you upload SRT files per lesson. And learners — especially non-native English speakers and hearing-impaired students — expect captioned content.

If you script your lessons before recording, CaptionFit is even faster: paste the script and it aligns to the audio instantly. No watching the recording back to find the timestamp. Export SRT files for each lesson and batch-upload to your platform.

If you also teach live classes or record informal lessons, see how teachers caption lecture recordings. For compliance guidance on video accessibility in corporate training, see how businesses handle ADA and WCAG compliance.
