The basics: organization vs. personal

Screenshots show the Japanese screens; the English screens have the same layout.

UNIHUB has two kinds of things: things the whole organization owns and things only you own. Once you know which is which, questions like "Who can see this?" and "Will I get notifications I didn't ask for?" answer themselves. This page is for first-time users, with analogies and a glossary.

① Start with the two scopes

Knowing these two scopes answers almost every "Who can see this?" question.

Organization scope (shared by everyone)

Shared by the members of the organization. When one person sets it up, it affects every member involved.

Examples: group chats / webhooks / integrations / roles

Personal scope (yours only)

Belongs to you alone. Your settings are invisible to other people and do not affect them.

Examples: chats (DMs) / MCP keys / AI API keys / notification settings / passkeys

② Quick reference by feature

"Who can see this?" and "Who can set it up?" at a glance.

③ Roles (permissions)

What you can do depends on your role. Higher in the list means broader permissions.

1. Owner: everything in the organization, including billing, deletion, and transferring ownership.
2. Admin: almost all day-to-day operation, such as managing members, integrations, and creating webhooks.
3. Manager: creating and running group chats (channels).
4. Member: chatting and reading in the groups they belong to. Cannot create new integrations.
5. Guest: only the specific groups they were invited to. The narrowest permissions.

④ The main concepts, explained simply

Each comes with an analogy. When you hit an unfamiliar word, come back here.

Group chat (channel)

[Organization scope]

Think of it as a meeting room.

• Only people in the room can see the conversation inside it. People who are not in the room cannot see the contents.
• It belongs to the whole organization, so everyone in the group shares its contents.
• Only a Manager or higher can create a new room.

Chat (direct message)

[Personal scope]

Think of it as a letter between two people.

• Only the sender and the recipient are involved. Even an Admin cannot read someone else's chats.
• Unlike groups, chats are personal scope. Your private conversations are protected here.

Webhook (inbound endpoint from outside)

[Organization scope]

Think of it as a drop-in mail slot on the wall of one specific room.

• It is an entry point that lets outside services (form responses, online store orders, GitHub, and so on) "drop" messages into one chosen group in UNIHUB.
• ★ Very important: a webhook can only drop in (write). It can never read past chat. Someone who can put a letter in the slot cannot read the other letters inside.
• Webhooks belong to the organization, so once created, the URL appears in the settings screen of every member of the same organization (this is normal).
• Only an Owner or Admin can create one. Regular members cannot.
• The destination is fixed to the one group you choose when creating it. Webhooks cannot post into chats (personal letters).
• Caution: the URL itself is a key. Anyone who knows the URL can post to that group, so do not paste it in public or hand it out.

MCP (control from an external AI)

[Personal scope]

Think of it as a personal key you hand to an outside AI.

• It lets external AIs such as Claude or ChatGPT operate UNIHUB (post messages, search, and so on).
• The key (API key) is personal scope. Only you can see the keys you create, and they act only within your own permissions.
• A key is shown once, when you create it. Do not share or publish it. When you no longer need it, delete it and that key is disabled immediately.

Integrations (Stripe, GitHub, LINE, calendars, etc.)

[Organization scope]

Think of it as automatic call forwarding wired to the office landline.

• They deliver store sales, code updates, LINE inquiries (LINE is Japan's most widely used messaging app), and more into a group chat automatically.
• They belong to the organization. Only an Owner or Admin can set them up, and what arrives is shared by the members of the destination group.

Notifications

[Personal scope]

Think of it as the volume settings on your own phone.

• Whether you receive notifications, and how loudly each group notifies you, is personal scope. Your settings do not affect anyone else.
• For each group you can choose All / Mentions only / None.

Ask an AI (@claude / @chatgpt / @gemini)

[Personal scope]

Think of it as an advisor you can call into the conversation at any time.

• Write @claude, @chatgpt, or @gemini in a message and that AI reads the conversation up to that point and replies with opinions, a summary, or the key points.
• Examples: "@claude what do you think of this discussion?" or, replying to meeting notes, "@gemini add XX to this and give me your take."
• If the AI you named is not available (on the Free plan, the monthly free AI credits run on Gemini), another available AI answers instead (the end of the reply shows which AI answered).
• Usage is counted per person (monthly free AI credits on the Free plan, Managed AI on paid plans). No API key registration is needed (not available in chats/DMs). The reply is visible to everyone in that group.
• ⚠️ Note: if the conversation or question is very long, the amount the AI has to process (tokens) can hit the limit and no reply comes back. If that happens, shorten the question or narrow the scope and try again.
