About
Checksub AI is a comprehensive video localization platform that enables content creators, businesses, and educators to automatically generate subtitles, translate content, and dub videos into over 200 languages using advanced AI technology. At its core, Checksub offers three primary capabilities: automatic subtitle generation with high accuracy, AI-powered translation optimized specifically for subtitle formatting, and AI dubbing that replaces original voices with realistic cloned voices while preserving background audio and ambient sounds. Its voice cloning feature lets creators reproduce their voice-over in 30 languages with just one click, maintaining their unique vocal identity across markets. The platform includes voice isolation technology that separates speech from background music and noise, ensuring clean dubbing quality. Creators can further customize subtitles with dozens of style settings, animations, and karaoke effects, and export them as burned-in subtitle videos or separate subtitle files. A powerful online editor enables post-AI refinement, allowing users to edit and regenerate any subtitle or dubbing segment. Script-to-subtitle synchronization eliminates manual proofreading entirely. Trusted by 500+ companies, Checksub is ideal for training content, social media videos, YouTube channels, and any organization seeking to scale video content globally without reshooting assets.
