Buyer questions
Questions buyers actually ask
How is this different from auto-captions on YouTube?
Auto-captions transcribe words. OmniSubs understands context — tone, who is speaking, cultural references — then translates so the meaning survives, not just a word-for-word rendering.
Is my video uploaded to a server?
No. The original video never leaves your device — only the extracted audio is sent for transcription, and subtitle text for translation. Your footage stays private.
How long a video can I process?
Up to 10 hours. Audio is extracted and processed in chunks entirely in your browser, so even feature-length films and full lectures work without a huge upload.
