Reinventing Video Subtitling with Zero Cloud Uploads.
SubGenius AI was founded with a singular conviction: creators should never have to compromise their privacy or waste hours uploading massive video files just to add professional subtitles.
The Old Cloud Bottleneck
Traditional video editors force you to upload 2GB to 10GB raw video files to remote cloud servers. This exposes unreleased footage to third-party servers, causes upload stalls on everyday broadband, and drives exorbitant cloud egress fees that inflate subscription prices.
The SubGenius In-Browser Engine
SubGenius AI flips this paradigm. Using proprietary in-browser acceleration, your video stays 100% on your device. Only micro-signals needed for speech recognition travel through our encrypted edge network. You get instant results with zero video upload, zero data leaks, and zero egress fees.
