Shadcn Rich Text Editor 4 Block

For AI Agents

Hand your agent this brief or the ReUI MCP, not a screenshot. Installs with a ReUI Pro or Ultimate license.

Best for: A swappable Yjs room with scripted teammates to follow, an Online switch, comment threads to reply to or resolve and a session replay

When to use

Documents written and kept inside a product: launch briefs, wiki pages, contracts, specs and plans
Review on the text itself, through tracked suggestions to accept or reject or threaded comments
Shared writing with live teammates, or with an AI assistant whose edits arrive for review

When not to use

Contract edits that stay as attributed suggestions until accepted or rejected: use the Contract Redlines block
A single author page with slash commands, mentions and resizable tables: use the Wiki Page Editor block
The navigation layout around your pages, with no document editing in it: use the App Shell blocks
A top bar with a title, avatars and actions above a page you already have: use the Navbar blocks
A strip of formatting or alignment controls alone, with no document under it: use the Button Group component

Agent notes

openDemoRoom plays scripted teammates; give createRoomHolder your provider's room as a RoomAdapter and delete PEER_TRACKS
The ConnectionSwitch toggle reaches setOnline on the demo room through changeConnection; map that call to your provider's disconnect and connect
SPEC, THREADS and PEOPLE are the sample document, comments and teammates; currentTime returns a fixed demo date that stamps new comments
Each page.tsx wraps the root in an h-svh or min-h-svh column; inside an app shell drop it and size the root through className
Every schema starts from createRichTextExtensions in rich-text-extensions.ts; extend that list and keep it stable, as useEditor compares it by identity
Document typography is RICH_TEXT_PROSE in rich-text-content.tsx, built on theme tokens; restyle headings, lists, code and links there

Shadcn Collaborative Editor Block

Tiptap Collaborative Editor With Live Cursors, Presence, Offline Merge and Comments. Part of the ReUI Shadcn Application Rich Text Editor blocks collection.

Real time co-editing on Tiptap and Yjs: named teammate carets and selections, a presence stack you can follow, an offline switch that queues edits and merges them with no conflicts, and comment threads that sync. For specs, docs, wikis.

It is composed from Alert Dialog, Avatar, Badge, Button, Button Group, Card, Checkbox, Dropdown Menu, and more, so every part of it is a primitive you can restyle with your own design tokens.

What You Can Build With the Collaborative Editor Block

Install it with the ReUI registry command in the toolbar above, then swap the placeholder content, data wiring, and business logic for your own.
Compare it across all eight ReUI styles and both the Base UI and Radix bases in the customizer before committing to one direction.
Combine it with the other Shadcn Application Rich Text Editor blocks to assemble a full screen instead of a single section.
