Every word matters.
Know exactly where you deviated.
Upload your audio take, paste your script, and get word-level error detection with timestamps. Fix omissions, additions, and substitutions before you publish.
Welcome to precise spell-check for your audio recordings. Every word matters when you're delivering a message. Our technology compares your spoken take against your written script.
Features
Built for creators who care about every word
From podcast hosts to voice-over artists — catch every deviation before your audience does.
Record or upload
Record directly in your browser with a live waveform, or upload MP3, WAV, and M4A files — same analysis either way.
Phonetic tolerance
Near-matches flagged in amber, not red. Accent and regional pronunciation won't unfairly penalize your take.
Director's notes stripped
Parentheses, brackets, and scene headings are greyed out and excluded from scoring — only your spoken lines count.
Needleman-Wunsch alignment
Global alignment handles skipped words, reordered phrases, and repetitions more reliably than basic diff.
Click to seek
Click any highlight to jump the player to that moment — including interpolated timestamps for omissions.
Resolution tracking
Mark errors resolved as you re-record. Progress ring and bar update in real time.
Script alignment
Paste your script and we align every spoken word with Whisper word-level timestamps.
Perfect take
When every error is resolved, celebrate with a full-screen confetti moment.
