Why sublingo

Not another dub. Translations that feel like they were always there.

Every show, both platforms

Works on every title, every episode. Auto-enables English captions when a show needs them, and hides them the moment you want translation only.

YouTube N Netflix

Real-time, no waiting

The first translated lines land within seconds of pressing play. The rest fills in as you watch — and it's cached, so the next time is instant.

Bilingual or immersion

Stack both languages to learn, or hide the original for pure immersion. Toggle anytime.

Privacy-respecting

We translate the caption file the platform already serves — never your account, history, or the video itself.

Style it your way

Font size, color, background. Pick your OpenAI model for accuracy vs. speed. Settings follow you across devices.

Good to know

Questions, answered.

How much does it cost?

Free to try — 10 videos on real AI translation, no card required, and your first 3 don't even need an account. After that it's a simple monthly plan: Standard at $5/month for unlimited videos on fast AI, or Smart at $15/month for our best model. Cancel anytime. See pricing.

How accurate are the translations?

Powered by OpenAI models — far better than most automatic dubs, preserving context, idioms, and tone across cues. The free trial and Standard run on GPT-4o mini for speed; Smart upgrades to GPT-5.4 mini, which shines on idioms, register, and gendered languages.

Is it private?

We translate the subtitle text the platform already publishes — nothing about your account, viewing history, or video. Cue text is sent for translation and not stored beyond that request.

Which browsers work?

Any Chromium-based browser — Chrome, Edge, Brave, Arc, Opera. Firefox and Safari support is on the roadmap.
