chōboAI
Write it, ask it, change it. chōbo drafts the cards and suggests every change, and nothing happens until you approve.
Thoughts,sorted.
chōbo turns each thought into a clear card and suggests where it belongs. Nothing is saved until you say so.
Free during the beta. Private by design.
Organize
A place for everything.
Spaces hold the big areas of your life. Projects live inside them, and folders keep the busy ones tidy. Every card has exactly one home.
The card
The whole story, on one card.
Subtasks, related cards, files and a running log of updates sit with the date, the place and the priority. Nothing about it lives anywhere else.
On the web today. Coming soon to iPhone.

Thoughts, sorted. Together.
Ask, change, share.
musubi adds three things to chōbo:
- chōboAIAsk about your cards, and let chōbo draft and change them for you. You approve every change.
- TextingRolling out in the USText a thought from Messages or Siri, and it arrives as a card.
- Shared spacesPlan with family, friends or your team, all on the same cards.
TextingRolling out in the US
Catch a thought the moment it comes. Say “Hey Siri, text chōbo” or type it in Messages, and it becomes a card, filed where it belongs.
Shared spaces
One space for your family or your whole team. Everyone sees the same cards, and people you invite join free.
Why the name
Pull one end of a bow and it falls open in an instant. In Japan this knot is called a chōmusubi (蝶結び), and it’s the bow in our mark.
musubi is named after it: one quick pull, and a thought leaves your head and lands in chōbo, written down right where it belongs.
Privacy
Private by design.
chōbo follows the principles behind modern privacy law: collect only what’s needed, never sell it, protect it, and keep you in control of your own information.
Purpose limitation
Never sold, never for ads
Your information is used to provide chōbo. We don’t sell it, share it for advertising or run tracking scripts.
Consent and control
You’re in control
chōbo’s AI only suggests. Nothing is created or changed until you approve it, and preferences are remembered only when you ask.
Security
Protected by default
Your data is encrypted in transit and stored with Supabase, which encrypts it at rest. Strict access controls keep your workspace yours.
