Margin
A review room for copy, specs and policies. Each document is shared with the people who should see it, as editor or commenter, and that share is the database's access rule: someone it isn't shared with can't read the document, its comments or its live room. Reviewers comment on a paragraph, reply, react and resolve; every comment, reaction and resolve reaches everyone on the document live, avatars show who is reading it now, and readers see when someone is replying or editing the draft.
Members invited by the team. Each document has its owner, editors and commenters.
What's inside
Documents shared with you, by status. Paragraph comments with replies, reactions and resolve. Who is viewing now, who is replying, who is editing. Edits and status changes that appear live. New document and share dialogs.

How its workflows run
Each one is a server workflow in your project: it runs on its trigger, with retries, and its runs show in the builder's log.
- Make the creator a new document's owner and share it with the people picked
When a row changes:
doc created. Then: Create doc_access, then Look up member, then Notify. - Tell the people in a thread about a new reply
When a row changes:
comment created. Then: Look up member, then Notify. - Tell a thread's author when it's resolved
When a row changes:
thread updated. Then: Look up member, then Notify. - Tell everyone on a document when it's approved
When a row changes:
doc updated. Then: Look up doc_access, then Notify.
Set it up
It starts a new project, with its data, roles and sign-in ready.
- Start the project
Use the button above, or ask your coding agent with the Appbricx MCP server connected (quickstart).
- Sign in as each role
The demo logins open each role's home. Change what you like in plain words or in the contract.
- Deploy
When dev looks right, deploy. Production gets a snapshot first, so you can roll back.
Use it with your coding agent
The agent creates the project, builds it and signs in as each role.
Start a new Appbricx project from the Margin template (slug "margin") with use_template. Call it "My Margin", then sign in as each role, verify it and tell me what to change first.{
"tool": "use_template",
"arguments": {
"slug": "margin",
"name": "My Margin"
}
}appbricx templates use margin --name "My Margin"Goes well with
