The world's most advanced translator

Reach every audience on Earth — in their language, your story

The world's fastest and most advanced translator. Custom context-aware models that understand meaning like a human — dubbing a 10-hour video in seconds, across 60+ languages, without ever sounding robotic.

Context-Aware AI

The World's Most Advanced Translator

Our own custom models read the full context first — tone, intent, terminology — then translate the way a real human translator would. Idioms land. Names stay intact. Meaning is preserved. This isn't word-for-word. It's true localization.

The World's Fastest

Subtitles for a full 10-hour video in about 4 seconds. Stop waiting. Start publishing.

Character-Perfect Timing

Every dub stays in sync — never sped-up, never dragging. Intelligent character counting keeps speech natural, the way you actually talk.

Magic Mode

One click separates voice from music. Translate the dialogue while the original soundtrack, effects, and atmosphere stay perfectly untouched.

Voice Preservation

Natural, expressive voices in 60+ languages — keeping the tone, emotion, and personality of the original intact.

Review Every Word

Stay in control. Read and edit the transcript and the translation before export — nothing ships without your approval.

60+ Languages

Diarization

Help & FAQs

Everything you need to know about languages, credits, billing, and the workflows Octavia supports.

Octavia translates and dubs across 60+ languages — Spanish, French, German, Portuguese, Japanese, Korean, Hindi, Arabic, and many more — with automatic source-language detection. Every plan includes the full language library, so you can localize a single video into as many languages as your credits allow.
Credits are Octavia's single, shared currency. Video dubbing, audio translation, subtitles, and subtitle-to-audio all draw from the same monthly balance, so you spend it however suits your work. Each plan includes an allowance (Starter 6,000, Creator 12,000, Pro 30,000, Studio 120,000), and new accounts get 500 free credits each month to try things out.
Payments are processed securely through Stripe, so we accept all major credit and debit cards (Visa, Mastercard, American Express) and supported regional methods. Billing is monthly and your details can be updated anytime. Enterprise customers can arrange custom invoicing by contacting our team.
Yes. Octavia is modular — run a single workflow on its own whenever you like. Generate or translate subtitles without dubbing, translate an audio track without touching the video, or produce a transcript only. You're never forced into the full pipeline, and you only spend credits on the steps you use.
Credits are charged per minute of media processed, at a rate that depends on the workflow: video translation 100 credits/min, audio translation 80, subtitle-to-audio 60, subtitle translation 25, and subtitle generation 20. You see an estimated cost before confirming a job, and any job that fails is automatically refunded.
Anytime, with no contracts or cancellation fees. When you cancel, your account returns to the free tier and its 500 monthly credits, and you keep access to your existing projects. There's zero lock-in — your videos, audio, subtitles, and transcripts stay exportable at any time.
Yes. On Pro and above, Octavia automatically detects and separates speakers, giving each their own voice in the translated output so conversations stay natural. It's built for interviews, panels, podcasts, and anything with more than one voice — and you can adjust speaker assignments whenever you need.
Monthly plan credits refresh at the start of each billing cycle and don't carry over, so they're meant to be used within the month. Any additional credits you top up separately stay on your balance and aren't affected by the reset. If you consistently have credits to spare, a smaller plan may suit you better.
Nothing breaks — new jobs simply pause until you have enough credits again. You can wait for your monthly allowance to refresh or upgrade your plan to unlock a larger balance instantly. Your existing projects and outputs stay fully accessible the whole time.
The single-job cap is the maximum length of one source file you can submit in a single job. Creator handles files up to 120 minutes, while Pro and Studio go up to 10 hours per file. Larger libraries are no problem — split them across multiple jobs, or contact us about Enterprise for custom limits.
Anytime, in a single click from your billing page. Upgrades take effect right away so you get the larger credit balance immediately, while downgrades apply at your next renewal so you keep what you've paid for this cycle. Your usage history carries across the change.
Yes. Pro and Studio handle source files up to 10 hours long, and our distributed GPU processing turns hours of footage around in minutes rather than days. Feature-length films, full courses, and long podcasts are all supported — credits scale by duration, so you only pay for what you process.
