Understands meaning, not just keywords
Ask for “that email about money problems” and jo finds your budget discussions—even if you never used those exact words. Unlike Spotlight, jo understands what you mean.
100% private and local
jo runs entirely on your Mac. Your notes, photos, emails, and files never leave your device. Nothing is uploaded. Nothing is shared. Ever.
No subscription fees
Pay only for what you use—typically $5-10/month. Simple queries cost ~1 cent, complex queries ~5 cents. No monthly commitment.
Works across all your apps
jo searches Notes, Photos, Mail, Messages, Calendar, Files, Reminders, and Contacts simultaneously. One question, multiple sources.
How jo works
Unlike cloud-based AI assistants that require you to upload files and explain your context, jo already knows your world:- Indexes locally: jo connects directly to your Mac apps using the same APIs Apple uses for Spotlight
- Processes on-device: All AI processing happens on your Mac’s Neural Engine—no cloud required
- Understands context: jo remembers what matters across your notes, emails, photos, and files
- Answers instantly: Because everything is local, results come back in seconds
jo uses Apple’s M-series Neural Engine to run AI models directly on your hardware. This makes local AI fast, efficient, and completely private.
