Shadcn Rich Text Editor 5 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: An agent dock that maps typed asks to tasks by keyword, streams Edit and Add tasks as tracked edits and answers Review with findings

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

A plain writing surface with formatting tools and no assistant dock: use the Document Editor block
Human edits that must be tracked as suggestions for a reviewer to accept or reject: use the Contract Redlines 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

planAction plans each task with canned rules and no model call; swap it for your model's tool calls that return an AssistPlan
ASSIST_REWRITES, ASSIST_MISSPELLINGS, ASSIST_SUMMARY and ASSIST_CHECKLIST hold the canned text the tasks write; replace them with real output
DOCUMENT ships with seeded suggestions, so the dock opens on a review; pass content to open your own document
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
