How It Works
Three steps to a locked voice.
Stop re-explaining your voice to every AI. Lock it in once — use it everywhere.
Get Your Voice DNA
The Tone Scan engine maps your tone, rhythm, vocabulary, and signature phrases into a Voice Fingerprint.
Copy Your Signature Prompt
Paste it into ChatGPT, Claude, or any AI. Every draft now starts from your voice — not a generic blank.

Onboarding
One box, one email, then your voice.
Tonelocked keeps onboarding intentionally tiny: paste text, see value, then upgrade only when the output earns it.

Voice Transformation
Never sound generic again.

"We help ambitious brands sound unmistakably human—every single time AI writes."
Your Signature Prompt works in any AI tool you already use.

What a Tone Scan gives you
Five things, one paste box.
Tonelocked turns your archive into a living Voice DNA system your whole team can use — before any draft leaves the building.
Voice DNA
Maps your tone, rhythm, vocabulary, and persuasive patterns from real writing samples — the genetic code of your voice.
Tone Scan
Instant AI analysis of your sentence structure, word choice, reading level, brand personality, and signature phrases.
Signature Prompt
The product: a copy-paste block you drop into ChatGPT, Claude, Gemini or any prompt box so drafts start from your voice.
Voice Score
One number, 0 to 100, for how distinct and consistent your writing is. The same number every time you scan.
Voice Fingerprint
A one-paragraph summary of what makes your writing unmistakably yours — readable by a person, not just a model.
Voice Report
Your result at a public link you can send a client or a peer. They see the score and the phrases, not your prompt.
Portable, not locked in
It is text, so it works in every AI tool you already open — and in the next one, on the day it ships.
Example Voice Report

FAQ
Questions before you scan.
How does Tonelocked work?
Paste writing that sounds like you. The Tone Scan reads your tone, vocabulary, sentence rhythm and signature phrases into a Voice DNA profile, and returns a Signature Prompt you paste into any AI.
Which AI tools does the Signature Prompt work with?
All of them. It is plain text, so it works in ChatGPT, Claude, Gemini, Grok, Perplexity, Cursor, Notion AI, Copilot and any other prompt box.
Is this a subscription?
No. A Pro pass is $29.99 and an Agency pass is $79.99, each paid once and valid 12 months. There is nothing to cancel.
What happens after 12 months?
We email you a renewal link before the pass ends. If you let it lapse, your profiles and prompts stay visible and exportable — only new scans stop.
Why would an agency pay $79.99?
Because a Pro pass saves 3 Voice DNA profiles and an agency runs more clients than that. The Agency pass has no profile limit and shareable Voice Report links.
Can I not just write a voice prompt myself in ChatGPT?
You can, and some people should. A Tone Scan reads your real archive and names the patterns you cannot see in your own writing — and does it again for the next client.
What can I paste in?
Text: a newsletter, blog post, email, social post or transcript. 200 words or more works. File upload is not built yet.
How accurate is the Voice DNA profile?
It sharpens with more samples. A few strong examples give a usable Signature Prompt; a larger archive gives a more precise Voice Fingerprint.
Is my writing private?
Your sample is analysed to return your result. It is never used to train public models, and you can have it deleted by emailing us.
Do I have to give you my email?
Yes, one field, before the scan runs — that is how the Voice Report reaches you if you close the tab. No password, no name, no company, and one-click unsubscribe in every email.
How long does a Tone Scan take?
Twenty to forty seconds for pasted text, and the report lands in your inbox too, so you can close the tab.
Can I get a refund?
Yes. Inside 14 days, email us and we refund without argument.
