UnMarkAI

UnMarkAI is a translation tool that removes burned-in subtitles, then translate and dub videos. UnMarkAI cleans authorized videos by removing hardcoded subtitles and on-screen text, then translates, dubs and exports localized versions. It targets short drama teams, creators, agencies and learning teams, and offers APIs and an MCP server.

UnMarkAI is a web platform that combines video cleanup with localization. Its core idea is to prepare a clean source master first, then translate, dub and export that master for each target market. The cleanup stage handles hardcoded subtitles, timestamps, lower thirds, review labels and other owned on-screen text, and it also covers ordinary scene distractions. The site states that this happens without cropping the frame, with the area behind old captions reconstructed. The second stage covers translation. Subtitles and speech are converted into other languages, and the workflow asks reviewers to check product names, key terms and timing before delivery. Dubbing is part of the same flow, so voiceover, caption timing and delivery quality can be reviewed together. The homepage demonstrates this with a Chinese source clip offered in English, Japanese and Spanish versions. Removing the old subtitles first prevents source-language text from colliding with new captions or market-specific layouts. The audience is fairly specific. Short drama teams preparing vertical episodes for overseas release are a named focus, along with creators reusing owned clips, marketing teams and agencies adapting campaign or talking-head videos, and commerce or learning teams localizing demos, lessons and training. Developers get a Video Text Removal API, an asynchronous Video Translation API, documentation, an API console and an MCP server for agents such as Claude Code and Cursor. A usage restriction shapes the product. It is meant only for videos the user owns, licenses or is authorized to edit, and attribution, provenance, ownership marks, safety labels and required notices must stay intact. Among alternatives, it sits between general video translation and dubbing services and standalone watermark or text removal utilities. The pairing of a cleanup step with a translation studio is the main differentiator, which suits teams that repeatedly republish the same footage in several languages. Teams that only need subtitles generated for clean footage may find the cleanup layer unnecessary.
