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.
