GenSubAI is an AI-powered platform designed to help creators and teams localize video content and manage subtitles efficiently. Its suite combines automated video dubbing, subtitle translation, and subtitle extraction in one service, with tools aimed at both individual projects and large-scale workflows.

The dubbing feature processes uploaded videos in batches and produces dubbed output with precise voice-to-SRT timing alignment. GenSubAI highlights multithreaded processing, synchronized subtitles, and a library of voices covering more than 50 countries. For subtitle files, its translation service handles SRT and VTT formats, retains formatting, supports consistent terminology through a built-in glossary, and can process files with tens of thousands of lines using parallel translation.

The subtitle extraction tool uses OCR and audio or video recognition to identify text and generate SRT files. The platform also advertises denoising technology to improve extraction accuracy. GenSubAI offers pricing and credit-based usage, alongside account history, a blog, and customer support through Zalo. It presents its services as a way to reduce video-processing time and simplify content localization.
