Captioner
Add accurate subtitles to your videos and save hours of work
Captioner lets you add accurate subtitles to videos right in your browser. Upload a file, auto-transcribe with Whisper-based models, and edit precise timestamps in a smooth editor. You can translate captions into 98+ languages, export SRT, VTT, or SBV files, or download a video with burned-in subtitles up to 4K. Import existing transcripts to auto-align them. With high accuracy and word-level timestamps, it reduces editing time and fits into your video production workflow.
