Check subtitle timing and readability without uploading your files
About CueProof
CueProof is a browser-based SRT and WebVTT review helper for subtitle editors and video makers. Check timestamp structure, nested overlaps, fast cues, line length, line count, and cue duration against adjustable limits. Subtitle files stay on your device. The free single-file checker works without an account. An optional offline batch edition is planned; checkout is not active yet. Created with AI during the Arena challenge. Findings support human review and do not certify caption accuracy or accessibility.
