ON-DEVICEThe point of local

Why local AI?

Private

Your voice and captions stay on your PC — nothing is uploaded or logged to a server.

No usage fees

Local AI means no per-minute API bills — stream as long as you like for one small monthly plan.

Low latency

No round-trip to the cloud; captions appear as you speak.

Truly yours

The models live on your disk and keep working with no account and no cloud.

ANY PLATFORMWatch anywhere

Real-time translation for anything you watch

Not just your own stream — any video, on any platform.

OMNI listens to the audio playing on your PC or headset, so it live-translates any online video from any service — Netflix, YouTube, Disney+, Prime Video, Twitch, TikTok, and more. Because it runs on your machine, there are no per-minute fees, no matter how long you watch.

WORKS WITH ANY APP OR SITE THAT PLAYS AUDIO ON YOUR PC

USE CASESOne app, every kind of live

Built for how you stream — and watch.

How people use real-time captions — live streams and classes, plus shows and streamers that never get subtitles in your language.

FAQQuestions

Everything you might ask.

Do I need internet?

Only to download the app and models the first time. After that it runs fully offline.

Which streaming apps work?

OBS Studio and TikTok Live Studio, via a browser source or the native caption window — so CHZZK, SOOP, YouTube, Twitch and more all work.

Is my audio uploaded anywhere?

No. All transcription and translation happen on your PC; nothing is sent to a server.

What do I need to run it?

Windows 10/11 (64-bit) and a modern NVIDIA GPU are recommended for real-time speed.

How much does it cost?

Omni Live is free for 30 days. After that it's $4.95 a month or $47.40 a year, which is 20% off.

Until December 1, 2026 you can instead buy a lifetime license for $79.95.

Can I try it before I buy?

Yes. Every install comes with a full 30-day free trial with all features unlocked — no credit card needed. When the trial ends, enter a license key to keep going.

Can I move my license to another PC?

A key works on one PC at a time, and you can reset it up to 3 times from your account to move it to a new machine. The key is emailed to you right after purchase.
