Is this allowed at my university?
Policies differ. Source-only mode restricts generation to literature you uploaded, and every claim keeps its citation — so your work stays traceable. Check your examination regulations.
Does it work with Word on Mac and the web?
Yes. The add-in runs in Word for Windows, Mac and Word on the web, with the same project library across all three.
What is the difference between Premium and Ultimate?
Only the AI Advisor volume: 20 messages a month on Premium, 120 on Ultimate. Everything else — unlimited projects, uploads, autocomplete and Deep Review — is identical.
What happens to my thesis?
It is never used to train models. We name every processor involved in our privacy policy and delete documents when you do.
