Frequently Asked Questions

What AI is used for caption generation?
Captions are generated using AI, an automatic speech recognition model developed by OpenAI. It produces highly accurate transcriptions with word-level timestamps across 99 languages.

AI is highly accurate for clear speech and standard accents. For noisy audio or heavy accents, accuracy may be slightly lower — but for most content, AI captions match or exceed the quality of manual transcription at a fraction of the time.
