Checksub vs SRTGen

Checksub provides AI-powered subtitles, dubbing, and voice-over for videos through web, API, and extension platforms. It can create subtitles automatically or synchronize subtitles from a script, and it offers subtitle translation in 200 languages.

Translated-video publishing to YouTube is supported, and the Starter plan connects one channel. Listed integrations include YouTube, Twitch, Google Drive, Adobe Premiere Pro, DaVinci Resolve, and Final Cut Pro.

Checksub was founded in 2017 and is headquartered in France.
