CaptionLab: AI Subtitles

Turn any video into captioned, subtitled content in seconds. AI that truly understands your words — then translates them to 40+ languages.

CaptionLab adds accurate, beautiful captions to your videos in seconds — powered by AI that understands context, not just sound.

WHY CREATORS LOVE IT • Caption a full video in seconds — timed to the word • Context-aware AI fixes the names, slang, and terms other tools butcher • Translate to 40+ languages with natural phrasing • Studio caption styles — clean, karaoke highlight, bold pop, neon • Reposition, restyle, and fine-tune timing with a tap • Export captioned video in HD, plus SRT / VTT files
