Sharing and collaborating

There are four ways to show your work to someone else. Pick the one that matches what you want them to be able to do.

You want to…	Use
Send someone a read-only copy of a finished conversation	A snapshot link
Work inside the same chat with other people, live	A collaborative chat
Let anyone see something the assistant built	Publish the artifact
Let other people use an assistant you’ve set up	Share the assistant

Snapshot link

Hover the chat in the sidebar, click ⋯ → Share. A link is copied to your clipboard straight away — there’s no dialog.

The link shows a copy of the chat as it was at that moment. Messages you add later don’t appear. To update the snapshot, click Share again.

Whoever opens the link sees the full conversation, who shared it, and a Clone Chat button that copies it into their own account. They can’t reply in your chat. They do need to be signed in to CoChat to view it.

If you delete the chat, the link stops working.

Collaborative chats

Any chat can become a group chat. Click Share in the chat header (also under the + menu as Share Chat).

Invite people

Enter an email address, pick Viewer or Editor, and click Add.

People with a CoChat account are added immediately and notified.
Anyone else gets an email invitation. The link in it is valid for five days and lets them create an account and land straight in the chat.

Shortcut: type @ in the message box, pick a person, and they’re invited as an editor when you send.

You can also ask the assistant: “invite my supervisor, name@university.edu, to this chat”. It checks the address with you, then CoChat asks you to confirm before anything is sent — nothing goes out unless you click Confirm. The person joins as an editor. The assistant can send at most three invitations per chat, and invitations from the assistant count toward the same daily invitation limit as the share dialog. In Slack or Discord channels and in automations, the assistant can’t invite anyone.

Link access

Under General Link Access, choose who can open the chat’s URL:

Restricted — only people you’ve invited.
Viewer — anyone with the link can read.
Editor — anyone with the link can read and write.

Copy Link copies the chat’s URL. Anyone who opens it with viewer or editor access joins automatically, and the chat appears under Group Chats in their sidebar.

Working together

Avatars in the header show who’s in the chat and whether they’re online. A typing indicator appears below the messages.
Each message carries its author’s name and avatar.
Editors can send messages; viewers see the chat but can’t write in it.
Only the chat’s owner can change people’s roles or remove them (People with access in the share dialog).
In Chat Controls (the header ⋯ menu) you can set AI Response Mode to Always respond or Only when #mentioned, so a group can talk among themselves without the assistant jumping in.
Each person pays for the messages they send.
The assistant doesn’t save personal memories about you from a group chat — see Memory.

Sharing a whole project gives the same link access to every chat in it.

Messages between your chats

In a shared chat, the assistant acts for the person who sent the message. When you send, it can message your other chats; when another person sends, it can message theirs. You need write access to the sending chat.

A chat can reply to the chat that contacted it, including another person’s shared chat, while you still have write access there. Your permissions and billing apply to the exchange, not the shared chat owner’s.

If a chat is answering someone else, your incoming peer message waits for a separate turn acting for you. If you lose write access before delivery, that message fails instead of starting a turn as someone else.

Delivered messages and replies are part of the shared conversation. Other participants and their later turns can read them, just like other tool results. Only ask another chat to return information you want everyone here to see.

Between different assistants, your Can message permissions apply. A chat with no assistant can start an exchange with an assistant you own, including your default assistant, but not one someone else shared with you. It can still reply to a chat that contacted it. An assistant grant does not replace write access.

Publish an artifact

Open the artifact and click the globe icon (Publish) in its toolbar.

Tick Publish this artifact. Anyone with the link can view it, no account needed; your chat stays private. Changes save immediately — there’s no Save button.
Copy link, Open, or share to X, LinkedIn, Facebook or email.
Optionally tick List in public artifact directory and pick a category so people browsing the public gallery can find it. Listings are reviewed before they appear in the gallery; the link itself works straight away.

Visitors see the artifact full-screen, can download it, and can click Use in new chat to take a copy into their own CoChat.

To share an artifact privately with specific people instead, use the people icon (Share) beside the globe. It works like chat sharing: invite by email as viewer or editor, or set link access. You can also grant your assistants access to it.

If you delete the chat an artifact came from, the artifact — and its public link — go with it.

See Sharing an assistant. In short: invite collaborators as viewers or editors, or publish a public profile that anyone can add to their own account. Your tools, memory and credentials never travel with a public profile — each person gets their own copy.
