About jo

jo is a local AI assistant for Mac that runs entirely on your computer. It indexes your files, emails, and browsing history to provide context-aware answers without sending data to the cloud. Think of it as an AI that already knows your world.
Unlike cloud-based assistants, jo runs locally and already knows your context—your files, emails, and browsing. No need to copy-paste or re-explain your situation each time. It’s like having an AI with a perfect memory of your digital life.
Apple’s M-series chips (M1, M2, M3, M4) have a Neural Engine that makes local AI fast and efficient. jo uses this dedicated AI hardware to run models directly on your Mac without needing cloud processing.

​
Privacy & Data

jo can index your local files, emails (via IMAP), and browser history. You control exactly what jo sees through granular permissions, and everything stays on your Mac.
Never, unless you explicitly choose to. jo runs entirely on your Mac. When you optionally call in a cloud model like GPT or Claude, only that specific conversation is sent—never your indexed data.
jo runs 100% locally on your Mac. Your data never leaves your device unless you explicitly choose to send a specific conversation to a cloud model. No account required, no data collection, no tracking.

​
