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.
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 AIAI ChatAI ReviewBYOK
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.
YjsPresencePer-author undoSelf-hosted
Structured content
JSON, Markdown, render, validate.
Round-trip rich text into semantic JSON, export Markdown, render server-safe HTML for email and downstream consumers, and validate before save with the built-in schema hooks.
JSONMarkdownSSR renderValidation
Proofing and compliance
Spell check, accessibility, readability.
Give authors quality gates before content ships: native spell-check support, resolver-backed suggestions, accessibility checks, readability stats, and paste cleanup for Word and Google Docs.
Use it with your stack
A rich text editor for every framework.
The editor is static JavaScript, so it drops into any stack. Each guide has the install, the binding, and a working upload handler for that framework. Not using a framework? Start with the WYSIWYG editor overview.
