Gets things done
Creates Notion pages, checks your calendar and drafts emails. It always asks before changing anything.

Your AI, with a face.
Nanno is a little black cat that lives on your desktop. It talks to the AI you already use (ChatGPT, Claude, Gemini, DeepSeek, Grok and more) and gets things done in Notion, Calendar and Gmail. Your conversations stay on your computer.

A cat that actually helps
Talks back
Ask out loud and hear the answer in a natural voice that runs 100% on your machine.
Remembers your day
A private journal of what you did, ready for “what did I do yesterday?” or your weekly recap.
Private by design
Chats, journal and integration logins never leave your computer. No Hanno AI in the cloud, and we never sell data.
Study buddy
Summaries, quizzes and focus sessions built from your own material.
Make it yours
Skins and voices: astronaut, wizard, neon… plus limited editions every season.
Your AI, not a big-tech assistant
Nanno puts a face on the AI you choose, and keeps your life on your own computer.

The origin story
Meet the real Nano
Nanno exists because of Nano, a real black cat who spends her days on my desk watching me work. I wanted an assistant with the same quiet company: always there, never in the way.
