Meet Tuhi, your storage assistant

Tuhi is Storage Studio's assistant. You type a question into the Ask box on the Home screen — "why is my disk full?", "what did I move to my drive?", "how do I back up my photos?" — and Tuhi answers in plain English, then offers one button that takes you to the right place. Tuhi runs on your Mac. Where Apple Intelligence is available and turned on, it writes Tuhi's answers using Apple's on-device model; everywhere else, Tuhi answers from Storage Studio's built-in replies.

What Tuhi knows

• How Storage Studio works. A set of curated answers ships inside the app, along with Storage Studio's help library, which refreshes at most once a day.
• Your Mac, right now. Free space on your Mac and your external drive, whether automatic actions are paused, your rules and schedule, memory and processor load, and your Mac's name, model and macOS version.
• Your own history. What you've moved or offloaded and why, your backups and when they last ran, your connected cloud accounts and paired devices, recent background activity, and what's in the Recycle Vault.
• Where a file is. Ask "where is my Projects folder?" and Tuhi looks it up on your Mac and tells you the exact location, including whether Storage Studio moved it to your drive.

Tuhi keeps totals for clear-ups, not lists of every file removed, and it says so rather than making a list up.

What Tuhi can do

• Take you to the right screen. Most answers come with one button, such as Manage Apps, Find Duplicates or Open Recycle Vault, plus the exact steps to get there.
• Download a link. Paste a web link and ask Tuhi to download it, and it starts the download into your Downloads folder, with a live progress card in the conversation.
• Get you to a person. Ask to contact support, and Tuhi opens a support ticket form for you to fill in and send. Ask about "my ticket" and it tells you where your tickets stand. See Getting help.

Tuhi suggests and guides; it doesn't move or delete anything on its own from a question. Anything it points you to runs with that feature's usual checks and confirmations.

Tuhi is also the Run Tuhi button

The big Run Tuhi button on the Home screen runs Smart Care, the one-tap routine that clears caches, reclaims old local backups and keeps cloud files online-only. After a run, Tuhi sums up what it freed.

Where to go next

• Asking Tuhi a question — where the Ask box is and what to ask.
• Where Tuhi's answers come from — the badges on each answer.
• Tuhi runs on your Mac — what Tuhi reads and what it never sends.
• Tuhi on a Mac without Apple Intelligence.
• Letting another AI assistant read your storage — if you'd rather ask a different assistant.
