jo 1.0 — macOS AI assistant interface showing voice, chat, and integrations
● Now in Beta

Your AI. Your machine.
10x faster.

Half of me runs on your Mac. Half on a dedicated cloud machine that only you use. I work across macOS, Telegram, and WhatsApp. I actually know you — without handing your data to a shared cloud.

10x faster everywhere

Planning a trip, prepping for a meeting, or packing the car with your hands full.

I notice things

You've been browsing Yosemite trail guides, checking campsite availability, reading about kid-friendly hikes.

A local model on your Mac groups all of this into a clip: "Yosemite Weekend Trip." You never tagged anything or created a folder. I just noticed. Nothing left your machine. But when you ask me a question, I already have the context.

I know you

I know your kids' ages, that you prefer tent camping over cabins, that you always pack the car the night before. Plain text notes, daily logs, decisions — not a black box. Just files you can read and edit. A nightly reflection loop makes me better at helping you without you doing anything.

Voice while your hands are full

You're packing the car.

"Hey Jo, what's the weather in Yosemite this weekend?" Transcription runs locally on your Mac. Echo cancellation means no headphones needed. You talk while you work. I respond.

Always in your messengers

On the road, text me on Telegram to find a lunch stop. At the campsite, send a voice message on WhatsApp: "What time does the visitor center close?" I respond in audio. Your phone is always with you. So am I.

Deep app integrations

I check your Google Calendar for conflicts, read your Gmail for the reservation confirmation, pull up trail photos from your Photos library. Local: Safari, Chrome, Notes, Slack, Messages, Photos, Reminders, Finder. Remote: Google Calendar, Gmail, Google Drive. With your permission, I read actual content — not screenshots.

I work when you're not there

The morning of your trip, I send a briefing.

Weather forecast, check-in time from Gmail, a reminder to pack the hiking boots, current road conditions. Set it up once: "Every Friday before a weekend trip, send me a prep briefing." I run on your dedicated machine and deliver to whichever channel you're on.

Same me everywhere

Voice on your Mac at home. Telegram in the car. WhatsApp at the campsite. Same memory, same personality, same context. One conversation across every channel.

Raw power, but fast

Quick questions come back in 1–2 seconds. Complex research auto-routes to a reasoning model. You don't choose. I do.

Models

You pick the models

OpenAI, Anthropic, Grok, Kimi. More coming. I also ship with a local model that runs entirely on your Mac. Swap anytime.

Browsing

Real browser, not a simulation

I control a real browser on a separate machine. I check campsite availability on recreation.gov, read trail conditions on NPS.gov, find gas stations along your route. Sites see a normal user, not a bot.

Privacy

vs. ChatGPT

ChatGPT requires uploading files to their servers. I already know your stuff because I live on your machine, not theirs.

Up and running in minutes

1

Sign up

Create your account. Your machine spins up automatically. No terminal, no config files.

2

Connect your apps

Grant permissions to the apps you use. I index your Notes, Photos, Mail, Calendar, and Messages.

3

Ask anything, anywhere

Mac, Telegram, WhatsApp, voice. One conversation across every channel.

Built for daily life

I'm not a developer tool. Not a chatbot. An assistant that actually helps.

"Prep me for my 2pm with Sarah Chen"

I check your calendar, find your last 5 email threads with Sarah, pull up notes from previous meetings, and remind you she mentioned her daughter's graduation.

"What was that amazing tempura place in Tokyo?"

I find your reservation email from 2022, pull up the photos, and show the note where you wrote "best meal of the trip."

"What did we decide about the kitchen remodel?"

I pull together the contractor's quote from email, your photos, and the start date from Calendar.

"Catch me up on the family groupchat"

I read the last 100 messages in your iMessage, WhatsApp, or Telegram group and give you the highlights.

What early testers say

"Asked jo for 'that photo with the blue door from Portugal' from 2019. Found it in 3 seconds. 47,000 photos."
— Sarah M.
"4,000+ notes in Apple Notes over 8 years. Never looked at most of them. Now jo brings up relevant ones while I'm working."
— David R.
"I told jo about my kid's peanut allergy once. Now every restaurant recommendation and recipe it finds accounts for it automatically."
— Michelle T.

Your machine. Your data.
Not a row in someone else's database.

Real compute, real storage, only you.

A real machine that only you use. Your storage, your compute, your data.

Mounts as a drive on your Mac

Your cloud storage shows up in Finder. Trip notes, packing lists, conversation history. Regular files in a regular folder.

Personal data stays local

Photos, school schedules, screen content. All processed on your Mac. No network calls.

Inference you can trust

My cloud inference runs on providers contractually barred from training on your data. Run me fully local if you want.

I'm an AI assistant that runs half on your Mac, half on your own dedicated cloud machine. I search your notes, photos, emails, messages, and files. Available on macOS, Telegram, and WhatsApp.
Does my data leave my Mac?
Personal data (photos, screen content, local files) never leaves your Mac. Conversations and tasks run on your dedicated cloud machine. My cloud inference uses providers that never train on your data.

Every user gets their own cloud server. A real machine with its own storage accessible from your Mac.
How does pricing work?
Free during the beta. No credit card required.

OpenAI, Anthropic, Grok, Kimi, and a local model that runs entirely on your Mac. Swap anytime. I auto-route between fast and reasoning models based on the question.

ChatGPT lives on someone else's server and doesn't know you. I have your context (email, calendar, files, conversations) and run on your own machine.
Can I use jo on my phone?
Yes, through Telegram and WhatsApp. Text or voice. Same memory, same context as the Mac app. Native mobile app coming soon.
Which Mac?
Any M-series chip (M1 through M4) with 16GB RAM. Most Macs from 2020 onwards.
