AI subtitles, dubbing and 200-language video translation in one browser editor
Generates accurate captions with AI, then lets you apply dozens of style presets and animations, including one-click karaoke effects, before exporting burned-in video or subtitle files.
Machine translation built specifically for subtitles, so line lengths and timing stay readable instead of copying a generic document translator.
Separates music and background noise from the original voices, then replaces only the speech with realistic AI dubbing so the audio atmosphere is preserved.
Clone a speaker's voice from a sample and use it to replace the original voice-over across dozens of languages with a natural delivery.

Automatic subtitling proofread by an AI Reviewer, in 90+ languages
An automated proofreading pass reads every subtitle and fixes glossary names, hesitations, awkward phrasing, spoken-language slips, spelling, numbers and typography before export.
Transcribe speech with speaker identification and time subtitles, then translate into more than 90 languages using a glossary of your own terms.
Share videos or whole projects, let collaborators comment and edit by role, and track review progress across a team with named tags and shared terminology rules.
Export SRT, VTT, TXT or an MP4 with burned-in subtitles depending on your plan, plus a free SubReviewer tool to proofread subtitle files you already own.
