Does Click Clack add a watermark to my manuscript?
Click Clack doesn’t add a watermark to your manuscript. Text from a model or pasted from elsewhere may already contain watermark signals. The receipt is a separate file; it does not remove those signals. Native paste recording is automatic, with coverage gaps during shared editing. Downloading and sharing the receipt is optional. This documentation is customer-facing. It is not an internal runbook. The job it has to do:- Help a writer export a signed history from Click Clack.
- Help a publisher, editor, or platform check that file without a Click Clack account, and without trusting Click Clack’s website to tell the truth.
Check a receipt
Independently verify a signed history. No app. No account.
Export signed history
Download the JSON receipt from Activity, not the Markdown manuscript.
What a result means
What a valid receipt proves, and the claims it refuses to make.
Timestamps
Optional OpenTimestamps evidence, and why a “confirmed” label is not authority.
Who this is for
Writers who need to explain their process — novelists, journalists, and anyone else whose publisher, editor, or platform will ask what a machine contributed. The person you hand the file to is the second reader of these pages. They should be able to follow Check a receipt without signing in.What you will not find here
Operator runbooks, design-system internals, and working notes stay in the product repository. They are not this site.Verification is never colour alone. In Click Clack a signed contribution shows an icon and a label. On this site, a check is an exit status from the verifier, not a green badge in a screenshot.
