Shadcn Rich Text Editor 3 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: Changes from 3 reviewers with an avatar, name and time per row, an Editing, Suggesting and Viewing select and a margin that becomes a Sheet

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

Teammates co-edit one draft live and need to see each other's carets: use the Collaborative Editor block
Suggestions come from an AI assistant that streams its edits into the page: use the AI Writing Assistant 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

CONTRACT, CONTRACT_META and PEOPLE in data.tsx are the demo MSA, its header facts and the three reviewers behind the seeded suggestions
CURRENT_AUTHOR signs new suggestions and currentTime returns the fixed DEMO_NOW, so new changes carry the demo time
ContractEditor takes only className and content, and onUpdate just restamps the header, so persist the redlines yourself
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
