Frequently Asked Questions
- How does the auto caption generator work?

- For clear speech, Whisper's transcription is highly accurate and usually needs no editing. The captions are burned directly into the video in one step — upload, process, download.

- Whisper AI supports 99 languages. You can select a specific language for best accuracy, or use Auto-detect to let the AI identify the language automatically.
