Manuscripts before submission
Catch pacing issues and dropped threads before an editor does.
Story Lab
Test your readers before you submit.
Surface plot holes, character resonance, pacing problems, and reader reaction to your manuscript, screenplay, or arc — before it lands on an editor's desk.
The problem
Beta readers are few, slow, and polite.
Most authors get notes from a small group of friends and one or two industry contacts. The first time you hear from a real audience is when the book drops — and by then it's too late to fix anything. Story Lab gives you a synthetic readership that's diverse, blunt, and immediate.
