# Does Tuhi use my Mac's real storage numbers or guess?

Tuhi uses your Mac's real numbers and never guesses them. Free space, the biggest space-users, and how much has been moved or freed are read from the very same figures shown on the Home screen, so an answer never disagrees with what you can see.

When Apple Intelligence writes the wording of an answer, Storage Studio checks it sentence by sentence against what it really knows, and leaves out anything it can't back up — including any size or percentage about your Mac it wasn't given. If Tuhi hasn't finished reading your storage yet, it says so — "I'm still reading your storage — give me a moment, then ask again" — rather than inventing a figure. See [why Tuhi sometimes says "I don't know"](https://storagestudio.us/faq/tuhi-assistant/why-does-tuhi-say-i-dont-know).
