Turn English product demos into 73 languages with per-sentence review, brand glossary, and voice cloning. Ship localized onboarding in hours, not weeks.
Traditional dubbing breaks the onboarding flow your product team worked so hard to design.
Hiring voice talent, recording, re-recording, and syncing takes 2-4 weeks per language. Your onboarding flow stays English-only while competitors ship localized.
Different translators and voice actors produce wildly different terminology and tone. Customers get a disjointed experience across languages.
You receive a finished dubbed video with no way to fix a mistranslated feature name or awkward phrasing. Mistakes ship to production unnoticed.
Every sentence is reviewable. Every term follows your glossary. Every voice stays consistent.
Approve, edit, or reject each translated line before dubbing. You stay in control of every word that ships.
Define product names, feature names, and industry terms once. They are enforced consistently across all languages and projects.
Clone your existing narrator's voice and reuse it across all languages. No scheduling, no studio time, no re-recording.
Submit one video and receive 73 localized versions simultaneously. Ship to every market at once.
From upload to localized onboarding in four reviewable steps.
Drop your MP4 or import from a URL. Automatic transcription captures every word.

Product and growth teams use DubRelay to ship localized onboarding faster.
We localized our onboarding flow into 6 languages in a single afternoon. The per-sentence review meant our PM could catch every mistranslated feature name before it shipped.
The brand glossary is a game-changer. Our product name finally sounds the same in Japanese as it does in English. No more confused support tickets.
