# Does Tuhi use a lot of battery or slow my Mac down?

No. Tuhi does its work when you ask a question — it reads your Mac's resources once at that moment rather than monitoring constantly, and what it has already worked out is reused so repeat questions are quick.

When Apple Intelligence writes an answer, your Mac does a short burst of on-device work, then goes quiet again. Between questions, Tuhi isn't doing anything in the background.
