What is Checksub?
Checksub automates subtitle creation, translation, and AI dubbing for video content, supporting over 200 languages.
It converts audio or scripts into synchronized subtitles, then translates them with a workflow that first transcribes the original audio for higher accuracy.
The dubbing feature replaces original voices with realistic AI‑generated voices while preserving background audio, and it offers voice cloning and isolation for clean output.
Users can style subtitles—burn‑in, animated, karaoke—and export them as files or embed them in the final video.
An online editor allows sentence‑level editing and regeneration after AI generation, ensuring precise alignment and quality.
The platform supports API integration, downloadable translations, and is used for training videos, social‑media publishing, and multilingual YouTube channels.
