Context-aware AI subtitling
Subtitles that understand what was actually meant.
OmniSubs transcribes and translates videos up to 10 hours long — reading tone, character, and cultural context so the meaning survives the language, not just the words.
See the difference
Same 15-second clip, same voice, same timing. Watch how a literal word-for-word translation breaks every idiom while OmniSubs preserves the meaning, register, and emotional tone of the original.

Why OmniSubs
One clip. Every language. Context intact.
It reads the room, not just the words.
Most tools translate line by line and lose the meaning. OmniSubs weighs tone, who is speaking to whom, and the cultural reference behind a phrase — so a joke lands as a joke and formality stays formal.
- Tone & register preserved per language
- Character relationships tracked across a scene
- Idioms mapped, not transliterated
Made for long videos. Your original file stays on your device.
Feature films, lectures, full streams: OmniSubs handles videos up to 10 hours. Your original video never leaves the browser — only the extracted audio is processed, so your footage stays private by design.
- Up to 10-hour videos, no re-encoding
- Video never uploaded — audio only
- 80 source and 80 target languages
Now in real time
Live captions and translation for anything your PC plays.
Omni Live is a Windows desktop app that transcribes and translates any audio on your computer as it happens — the streams you broadcast and anything you watch, from Netflix and YouTube to any player. It runs locally on your machine, so nothing you watch leaves your device.

Questions
Everything you might want to know.
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.
How long a video can I process?
Up to 10 hours. Your browser extracts and splits the audio into chunks for AI transcription; subtitle text is then sent for translation. The original video file stays on your device.
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.
Which languages are supported?
Transcription in 80 source languages and translation into 80 target languages, each with register and idiom handling tuned per language.
What does it cost to start?
Sign up and you get 200 free credits — enough for a 100-minute video — with no credit card. After that you pay only for the audio you actually process, or save with a pack or subscription.
How long does a long video take to process?
Most of the work happens on your device: audio is extracted locally, and only a compact audio stream — about 14 MB per hour of video — is uploaded, never the video itself. Transcription runs in 10-minute chunks with live progress, so even multi-hour files move through steadily. Total time depends mostly on your connection speed.
What happens if something goes wrong mid-job?
You are only charged for audio that was actually transcribed — a chunk that fails is not billed. Once transcription completes, your transcript stays loaded for the session: you can re-translate into any language or tone without re-running (or re-paying for) transcription. Closing the tab discards an in-progress job, so keep it open until your subtitles are ready.
