Saved with quantum-proof encryption. Next time you need Netflix just say 'give me Netflix' and I'll send it. Nobody can see it — not even me on the server.
Your day, from inside
Proactive, not reactive.
MONO doesn't wait for you to message. It messages you when it matters.
'Daily brief' — arrives without asking, with your to-dos, weather, and any meetings today.
Photo of your lunch → calories counted + added to the day.
'Ana hasn't replied, want me to follow up?' — proactive.
'You spent $180 on Uber today, 60% above your average.' — warns you before you blow the budget.
Who uses it?
There's no "typical user".
Common questions
FAQ
Do I need to install anything?
No. MONO runs 100% on WhatsApp. Register your number, pay the subscription, and your MONO messages you first. Zero apps, zero logins.
Can it really make phone calls?
Yes, with the 'AI Calls' premium skill ($7 USD/month). MONO uses natural AI voice to call offices, restaurants, vendors and negotiate or book on your behalf.
How private is my data?
Each user gets their own dedicated VPS. All messages, files, and passwords are encrypted with AES-256-GCM + ML-KEM-768 (post-quantum). Zero-knowledge architecture: not even we can read your data.
Does it work for families or teams?
MONO is personal — one per person. But in a family, each member has their own and they can share document vault, shared calendar, and grocery lists.
