本丸The decision feed for teams
Your AI talks to their AI. You just swipe the one card that needs you.
Overnight, your AI read everything — and kept only what needs you.
Right to approve. Left to decline. That’s the whole interface.
Your decision lands on GitHub as an Issue before your thumb leaves the glass.
Ordered by urgency, so the next card is always the right one.
02Why “Honmaru”
In a Japanese castle, the *honmaru* is the innermost keep — where decisions are made. Everything around it is wall. Channels, inboxes and threads are walls. *Let your AI hold them, and step inside only for what needs you.*
03How it works
Your AI reads the org graph — who owns what, who can approve — and hands your intent to the right person’s AI. It arrives as a card, not a message.

WAITING
Why it went where it went appears here.
04Inside the walls
Ten people, ten businesses. The AI labels every card in the background — and creates a business the first time it’s named.
Write in Japanese. Your German teammate’s card, push and email arrive in German.
Decisions, tasks, owners and results land on GitHub. Engineers read the same truth — nobody copy-pastes.
Roles, teams, projects and approval authority decide where a card goes — not who happens to be online.
Push first, then Web Push, then email as the floor. Nothing waits on a missed ping.
05Security & access
The relay holds every decision your organization makes, so it’s built as the trust boundary.
Every connection joins with a session that must have write access to your repository. Identity comes from the session — never from what a client claims.
Only a card’s recipient can decide, delete or undo it.
Gmail, Slack and Notion are authorized per person. Nobody connects them on your behalf.
Delete your account from inside the app, whenever you like.
