Always watching, never leaking

I notice things you'd never think to save.

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.

Real memory, not a prompt

I know you — not your session.

Your kids' ages, that you prefer tent camping over cabins, that you always pack the car the night before.

Plain text notes and daily logs — 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.

What jo knows about you
👨‍👩‍👧‍👦 Two kids: Maya (8), Liam (5) · peanut allergy (Liam)
Prefers tent camping · always packs car night before
📅 Busy Thursdays · prefers morning meetings
🏃 Runs 3x/week · skips Mondays
Where you already are

I live in Telegram and WhatsApp.

On the road, text me 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.

Same memory, same context — whether you're at your desk or on a trail.

WhatsApp · Yosemite Campsite
🎤 "What time does the visitor center close today?"
🔊 Closes at 5pm today. Based on your check-in email, you're 12 min away. You have time.
Any good lunch spots on the way?
Iron Door Saloon in Groveland — 4.4★, kid-friendly, 6 min off your route. No peanut dishes flagged.
Set it once

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.

Friday Trip Briefing · 7:00am
🌤 Yosemite Valley: 72°F, partly cloudy. No rain.
🏨 Check-in: 3pm · Confirmation #YV-2847 (from Gmail)
🥾 Reminder: pack hiking boots (from your packing list)
🛣️ Hwy 120: normal conditions. Leave by 11am to avoid afternoon traffic.
No lock-in

You pick the models. I route between them.

"What time is check-in?" — instant, local model handles it. "Research the best kid-friendly trails and build a two-day itinerary" — I route that to a reasoning model automatically.

OpenAI, Anthropic, Grok, Kimi — plus a local model that runs entirely on your Mac. Swap anytime. You're never locked in.

Privacy by design

Your data, with evidence.

We don't ask you to trust us. We give you the tools to verify.

Personal data — photos, screen content, local files — is processed on your Mac and never transmitted. Conversations run on your dedicated server, not ours. Cloud inference providers are contractually barred from training on your data.

Run me fully local if you want. Zero cloud, zero inference, zero doubt.

Seriously: Check Activity Monitor. Read our privacy docs. Email privacy@askjo.ai. We welcome scrutiny.

Questions

FAQ

What Mac do I need?
Any M-series Mac (M1 through M4) with 16GB RAM or more. Most Macs made after 2020 qualify.
✓ Check your chip: Apple menu → About This Mac → Chip
Does my data leave my Mac?
Personal data — photos, screen content, local files — is processed on your Mac and never transmitted. Conversations and tasks run on your dedicated server. Cloud inference uses providers contractually barred from training on your data. Read our full privacy policy →
What's a "dedicated machine"?
Every jo user gets their own cloud server — a real machine with its own storage, accessible only by you. It mounts as a drive in Finder. Not a shared server. Not a container on someone else's instance. Yours.
How does pricing work?
Free during the beta. No credit card required. Everything included. We'll give you clear notice before any pricing changes — you'll never be surprised.
Which AI models can I use?
OpenAI, Anthropic, Grok, Kimi — plus a local model that runs entirely on your Mac. Swap anytime. jo auto-routes between fast and reasoning models based on the complexity of your question.
How is jo different from ChatGPT?
ChatGPT lives on someone else's server and has no persistent memory of you. jo runs on your machine, knows your actual context (emails, calendar, photos, notes, conversations), and works from Telegram and WhatsApp — no extra app required.
Can I use jo on my phone?
Yes — through Telegram and WhatsApp today. Text or voice. Same memory and context as the Mac app. Native mobile app coming soon.
