One Project, Every Language
Produce multilingual videos at scale. Automatic subtitles in 70+ languages, AI voiceover, and batch cloud rendering — localization that used to take weeks now takes minutes.
Video Localization is Broken
Traditional localization means sending videos to translators, waiting for subtitles, re-editing timelines per language, hiring voice actors, and rendering each version separately. A 5-language project can take weeks and cost thousands. MergeMate.ai's AI agent handles the entire pipeline — from your single master project.
One project. All languages. All formats. Rendered in parallel in the cloud.
70+ Languages
Automatic subtitle generation and translation in over 70 languages. From English to Japanese, from German to Arabic — powered by AI translation with custom vocabulary support for brand terms and technical jargon.
- ISO-standard language codes
- Custom vocabulary for brand terms
- Batch translation of entire projects

Batch Cloud Rendering
Render all language versions simultaneously in the cloud. One project becomes 10, 20, or 50 localized versions — with subtitles burned in, voiceover swapped, or both. No local GPU required.
- Parallel rendering of all versions
- Multiple aspect ratios per language
- Subtitle burn-in or separate WebVTT
- Cloud GPU — no local hardware needed
