Using the service
Zyphh provides text-analysis and writing-assistance tools. Use them only with material you're entitled to submit, process and edit. Don't use the service to violate anyone's rights, misrepresent evidence, harass someone, impersonate an author or bypass access controls. Don't automate requests to get around rate limits or to use up another user's processing allowance.
Automated results have limits
The detector uses a classifier evaluated on a documented benchmark. Its signal score is not an AI-authorship probability, and results may not generalize to your document. Character findings don't prove an intentional watermark, and optional statistical verification depends on a matching detector. Rule-based rewriting can still change meaning or grammar in contexts the rules don't understand.
None of these outputs establishes authorship, misconduct, factual accuracy or originality. Don't use a score as the only basis for a consequential decision about a person. Look at the writing context and the evidence underneath.
Your documents and revisions
Submitting a document doesn't transfer its ownership to Zyphh. You're responsible for having the permissions needed for the processing you ask for. Read the privacy page and the named provider's terms before sending material externally.
You're also responsible for checking revised text before you use it, keeping any necessary attribution and following the disclosure rules that apply to your work. A rewritten document can still be AI-assisted and may still carry a detectable statistical signal.
Availability, changes and contact
Local tools depend on browser support and on the published algorithm version. Optional integrations can be affected by outages, configuration or usage limits. When something fails, the error should preserve your source and explain what couldn't be completed. Methods and documented rules may change over time.
The technical limitations described in the methodology apply to the service, and nothing here removes rights that can't lawfully be excluded. For questions or technical reports, use the contact page.
