AI Toolkit Structured JSON Documentation

Build a familiar editor, then layer in smarter workflows

RichTextEditor helps teams create content for CMS pages, knowledge bases, email builders, intranets, and line-of-business applications.

Type directly in this editor, resize the area, then click Ask AI in the toolbar to try a proofread, rewrite, or summarize pass. Suggestions preview inline - nothing changes until you accept.

  • Clean HTML output for publishing and rendering workflows
  • AI Toolkit with Ask AI, AI Chat, inline review, and AI Review drawer
  • Per-node Yjs CRDT for character-level concurrent typing — how it works
  • Structured JSON, Markdown, static HTML render, and validation
  • Word and Excel paste handling with less cleanup
  • Toolbar, plugin, dialog, and API customization for developers

Start with the default setup

Then use the demos and documentation to tailor commands, uploads, styles, localization, templates, AI behaviors, structured content flows, and integration behavior for your product.

What’s in the box

A complete authoring stack — not a text area with hooks.

Reviewable AI, real-time collaboration, structured-content pipelines, and the customisation API teams actually use to ship product. Everything below ships in the base licence — no add-ons, no upsells.

New in 2.2

AI workflows

In-editor AI — reviewable by design.

Ask AI, AI Chat, and AI Review with inline preview. Nothing lands in the document until a reviewer accepts it. Suggestions stay queued in the drawer until they’re resolved — even across reloads.

Ask AI AI Chat AI Review BYOK

Real-time collaboration

Per-node Yjs CRDT — same-paragraph typing.

Two reviewers in one paragraph, character-level merge, presence cursors, per-author undo. Plug any self-hosted Yjs provider with one config option — no SaaS sync hub required.

Structured content
