AIStoryHub Labs · Free Tool
What does your writing actually sound like?
Paste a page of your prose. We'll read it the way Style Lab does: cadence, sentence shape, dialogue, the senses you reach for, and hand back a fingerprint instead of a grade. Nothing you paste ever leaves your browser.
Questions
How it actually works.
Does the Voice Fingerprint Analyzer send my writing anywhere?
No. It runs entirely in your browser, reading sentence length, punctuation, and word choice against a set of fixed rules. Nothing you paste is uploaded to a server or processed by an AI model.
Is this the same analysis Style Lab uses?
No, and we don't want to oversell it. Style Lab's voice analysis is a full AI read across 30 dials from at least 1,500 words, and it saves the result as a voice you can reuse in every chapter you generate. This tool is a free, instant, mechanical preview across 8 of those dials, computed from as little as 150 words. Think of it as the trailer, not the film.
How accurate are the scores?
They're a mechanical read, not a critical one: sentence length, punctuation density, and word lists standing in for things like pacing or vocabulary register. It's a useful directional signal on a page or two of your own prose, not a precise measurement, and it gets noisier on very short passages.
What is the archetype at the top of my results?
A one-line label generated from your dominant dial combination, like Kinetic & Talkative or Slow-Burn Interior. It's meant to be a fun, memorable summary of your fingerprint, not a genre or quality judgment.
Is it free? Do I need an account?
Yes, and no. Paste your text and get a fingerprint immediately. Nothing is saved anywhere unless you separately create a Style Lab voice from your own writing.
What is the sensory profile?
A read on which senses your prose reaches for: visual, auditory, tactile, or scent and taste, shown as a share of the sensory language actually detected in your passage. Passages with very little physical description won't have enough signal to show one.
