Upload a video, pick a language, get a dubbed video back.
Turn one product video into reviewable, on-brand versions for every market.
DubRelay is an AI-powered video localization platform that helps teams translate, dub, and subtitle videos in 73 languages — with a reviewable workflow that keeps your brand voice consistent across every market.
Unlike one-click "black box" tools, DubRelay lets you review and edit every line before export: transcription, translation, voice, and subtitles. This means you catch terminology errors, fix brand-specific terms, and approve the final output before it goes live.
| Problem | DubRelay Solution |
|---|---|
| AI dubbing quality is inconsistent | Line-by-line review before export — you approve every sentence |
| Brand terminology gets lost | Built-in Terminology Library + Translation Memory |
| Workflow is fragmented across tools | Upload → Translate → Dub → Review → Export, all in one place |
| Voice cloning sounds robotic | AI voice cloning preserves original speaker's tone and emotion |
| Lip sync doesn't match | AI lip sync aligns mouth movements with dubbed audio |
Review and edit transcription, translation, and voice assignment line by line. Catch errors before they reach your audience — not after.
Clone and reuse authorized voices across all your videos. Maintain consistent terminology, voice identity, and publishing style through the Brand Kit suite.
Clone any speaker's voice from a 5-second sample. The cloned voice preserves tone, emotion, and speaking style — then reuse it across all your projects in any language.
Automatically align lip movements with dubbed audio using AI-powered lip synchronization. No more mismatched mouths — your dubbed videos look natural.
Generate multiple language versions from a single source video. Create multi-language batches and track progress across all versions in one dashboard.
Remove burned-in hard subtitles from videos using AI inpainting technology (Auto mode with OpenCV for all plans, AI mode with Alibaba Cloud for Pro/Business). Clean up old localized videos before re-dubbing in a new language.
Generate timeline-aligned translated subtitles. Export as separate SRT files or burn them directly into the video with customizable styling. Supports 15+ writing systems including CJK, Arabic, Thai, Devanagari, and more.

Traditional video localization requires separate tools for transcription, translation, dubbing, subtitle creation, and video editing. Teams stitch together 4-5 different services, manually transfer files between them, and lose version control along the way.
DubRelay connects all these steps into one workflow. Upload once, review everything, export a publish-ready localized video. No file shuffling, no version chaos, no inconsistent terminology.
- Cost-effective: AI-powered pipeline at a fraction of traditional dubbing costs
