One voice, and it’s yours.
Your voice archetype
Thirteen dimensions, mapped into a portable, human-readable voice file. Your free starter file is ready below, and a copy goes to your inbox with the voiceprint ID.

The picture is yours either way, and it is drawn from your answers alone. So is the free file below, and it works on its own. The full voiceprint adds the sections tuned to you: your own anti-AI filter on top of the generic one, the calibration passages you picked, your protected phrases held exempt from that filter, a hard-rules block, and a check the model runs before it hands you the draft.

Your voice, read back to you
Where a model will be hardest for you to catch
Not a verdict on your writing. These are the places your own
preferences sit closest to what an AI does by default — which is exactly where
drift arrives sounding like you.
Your filter, running on a real AI draft
This is an unedited answer a current model gave to a real brief:
tell your readers you are raising your prices. It is competent writing. Here is what
your voiceprint flags in it.
your-voice.mdfree · starter
short, direct sentences that carry weight
a comfortable relationship with the em-dash
opens with the point, not a wind-up
irony deployed sparingly, never explained
first person, active voice, verbs that commit
sentence length swings on purpose
technical terms without apology
the occasional fragment. for effect
skepticism of tidy conclusions
metaphors from the workshop, not the boardroom
questions that expect an answer
no throat-clearing, no tidy bow
loyal to specific words, allergic to others
paragraphs that end early
a voice that argues with itself and wins

Check a draft against your own rules
Paste something your AI wrote. This runs entirely in your browser —
the text is never sent anywhere, stored or logged. It reports what breaks the rules
you set, and nothing else. There is no score, because a number on a short draft would
be inventing precision that is not there.
Tune it
These are the dials that change the output most. Move one and the file
above rewrites itself. Nothing is locked in — you can come back and move them again.
Or paste it straight into the box
Where to paste it
The file goes wherever your AI keeps its standing instructions. Once per tool, and
then it applies to everything you write there.
ChatGPT · Settings → Personalization → Custom instructions. Or paste it into
a Project so it covers just that work.
Claude · Projects → Project knowledge. Settings → Capabilities → Styles also
works if you want to switch the voice on and off.
Gemini · Gems → New Gem → Instructions.
Cursor, Copilot, and the rest · Save it as a rules file in the repo and it
rides along on every request.
You’ve built the voice. This is everything you can do with it.
The file above carries the baseline anti-AI filter and your whole style, and it works — we measured it, and it put 13 of 15 drafts inside the target rhythm, against 0 of 15 with no file. What the paid sections add is the part tuned to you: a filter built from the phrases you named rather than the generic ones, your signatures held exempt from it, dials that re-cut the file as you move them, unlimited variants for whatever room you are writing in, and the exports a builder needs. It is one payment and there is nothing after it.
