How to use your writing style fingerprint

The fingerprint isn't the end product - it's a reusable instruction set that teaches an AI assistant to write in a specific person's voice.

1

Paste a writing sample

Add 300+ words (ideally 500+) of the spokesperson's genuine, unedited writing in a single voice.

2

Run the analysis

We map the sample across 78 linguistic dimensions. This takes 1-2 minutes, so give it a moment.

3

Download the JSON

When the results appear, download the JSON fingerprint. The transformation rules inside are the part that does the work.

4

Drop it into Claude or a custom GPT

Upload the JSON into a Claude Project or a custom GPT, and instruct it to use the file's transformation rules as the guide for rewriting any content into that person's style.

Good to know

  • Quality depends on the sample. Use real, unedited writing - the more (and the more consistent the voice), the sharper the fingerprint.
  • A fingerprint captures one context. Someone's LinkedIn voice differs from their formal email voice - analyse each separately for best results.
  • It guides style, not facts. The rules shape how something is said, not whether it's true - always fact-check and have the spokesperson review.
  • It works best paired with a capable model (Claude or GPT) in a project with standing instructions, rather than a one-off paste.
