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.
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.
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.
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.
The jo app is free to download and use. Local AI queries are always free. You only pay for optional cloud model access (like GPT-5.2 or Claude) on a pay-per-use basis, typically $0.01-0.05 per conversation.
Most users spend less than $5/month on cloud model queries. Local queries are always free. There are no subscriptions—you only pay for what you use when you choose to call in more powerful cloud models.
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.
