jo is an AI that searches everything on your Mac—notes, photos, emails, messages, files—and finds what you need in seconds. Instead of matching keywords, jo understands meaning.

​
How jo’s search works

When you ask jo a question, it already knows your context. jo indexes your Notes, Photos, Mail, Messages, Calendar, and files locally on your Mac, so it’s ready to help the moment you install it.

​
Real example queries

Here are real questions you can ask jo:

Find emails

“Did my landlord ever get back to me about the leak?”

Find documents

“Where’s that W-9 from my accountant?”

Search messages

“What did I tell Jake I’d send him?”

Find notes

“What came out of my 1:1 with Sarah?”

Search browsing

“Where’s that Stripe page I had open?”

Gather context

“Help me pull together my competitor notes”

​
What makes jo different

​
vs. Spotlight

Spotlight matches exact words. jo understands meaning. Ask for “that email about money problems” and jo finds your budget discussions—even if you never used those words. Example: You search for “that photo with the blue door from Portugal” from 2019. Spotlight fails because you never tagged it. jo finds it in 3 seconds because it understands what you mean.

​
vs. ChatGPT

ChatGPT requires uploading files to external servers. jo already knows your stuff and never sends anything anywhere.

​
vs. Rewind

Rewind records your screen (privacy nightmare). jo reads your actual files using the same APIs Apple uses. No screenshots, no recordings.

​
vs. Note apps

Notion AI only searches Notion. jo searches Notes, Photos, Mail, Messages, and Calendar at once.

​
Cross-app intelligence

jo connects information across apps in ways that weren’t possible before.

Meeting prep

Ask: “Prep me for my 2pm with Sarah Chen”jo finds:
  • Your calendar event
  • Last 5 email threads with Sarah
  • Notes from previous meetings
  • That she mentioned her daughter’s graduation
All from Calendar, Mail, and Notes at once.

Travel memories

Ask: “What was that amazing tempura place in Tokyo?”jo finds:
  • Your reservation email from 2022
  • Photos you took of the food
  • The note where you wrote “best meal of the trip”
All connected across Mail, Photos, and Notes.

Project context

Ask: “What did we decide about the kitchen remodel?”jo finds:
  • Notes on cabinet styles
  • Contractor’s email with the quote
  • Photos of inspiration kitchens
  • Calendar note about the start date
Everything you need from four different apps.

​
Understanding vs. matching

Traditional search matches keywords. jo understands meaning.
How it works: jo uses AI to understand the semantic meaning of your question and your content. It can find things even when you don’t remember the exact words.
Traditional search:
  • Searches for exact keyword matches
  • Requires you to remember specific words
  • Can’t connect information across apps
  • Returns a list of files
jo’s AI search:
  • Understands what you mean, not just what you say
  • Finds relevant content even with vague descriptions
  • Connects information across Notes, Mail, Photos, Messages
  • Gives you answers, not just file paths

​
Speed and privacy

jo indexes everything locally on your Mac. Nothing leaves your machine. Ever.
  • Fast: Search results appear in seconds because everything is already indexed
  • Private: Your data never gets uploaded anywhere
  • On-device: The AI model runs locally on your Mac’s Neural Engine
  • Always ready: jo continuously indexes new content in the background
jo runs 100% on your computer. Your notes, photos, and emails never get uploaded anywhere. Nothing is shared. Nothing leaves your machine. Ever.

​
Use cases

​
For professionals

“Catch me up on my emails with the accountant” — jo knows your inbox “What was that productivity podcast I started?” — jo knows your browsing “What did I learn at that conference last year?” — jo finds notes, photos of slides, business cards, and follow-up emails

​
For personal life

“What did Sarah say about the deadline?” — Search across iMessage, WhatsApp, Telegram “Where’s that contractor Mike recommended?” — jo finds the message, the phone number, and the photos “Help me prep for this salary negotiation” — jo gathers your notes, relevant emails, and past conversations
The more you use jo, the better it gets at understanding what you’re looking for. It learns your terminology and how you organize information.
