Questions, answered.
Can I import from Google Docs?
Google Docs snapshot import is being prepared for a future release. It will be optional and require Google sign-in and read-only consent covering all Docs available to your account. InkWho will retrieve only the document you request; you will preview a selected tab before replacing text and starting local analysis. Read the planned import steps and privacy policy.
What does the score mean?
Higher scores indicate more AI-like writing patterns. The score is an estimate, not proof of authorship or the percentage of AI-written words. Understand the scores →
Which browsers and languages are supported?
InkWho currently supports English text in desktop Chrome.
Why does the first check take longer?
The first check needs a little time to get ready. Text length and your device also affect check times.
Can I pause automatic checks?
Yes. Pause a website or turn off automatic analysis in the extension menu.
