WYSIWYG editor

A WYSIWYG editor that gives you back what you saw.

WYSIWYG is a promise about output: the document the author composes should be the document your application stores and renders. RichTextEditor keeps that promise with clean, predictable HTML and a preview stylesheet that renders saved content exactly as it was authored — on your own servers, under a perpetual license.

What WYSIWYG should mean

Three things people actually want.

The output matches the screenA preview stylesheet renders saved HTML the way it was authored, instead of leaving you to guess.
Paste does not wreck the documentWord and Google Docs paste is cleaned to your rules rather than carrying foreign markup in.
Nothing leaves your serverUploads, documents and AI calls route through endpoints you control. No per-load metering.

Add one in three tags

No build step and no framework required — it is plain JavaScript, so it runs anywhere a <script> tag runs.

<link rel="stylesheet" href="/richtexteditor/rte_theme_default.css" />
<script src="/richtexteditor/rte.js"></script>
<script src="/richtexteditor/plugins/all_plugins.js"></script>

<div id="div_editor1">Start typing...</div>

<script>
    var editor = new RichTextEditor("#div_editor1");
</script>

Getting the document back out

Store it like any other user-submitted HTML — and sanitize it server-side before rendering it to other users. See why “nothing executes in the editor” is the wrong bar.

// What the author saw is what you store.
var html = editor.getHTMLCode();

// Render it back with the same stylesheet the editor used and it looks
// identical. This is the part most "WYSIWYG" editors leave to you:
// <link rel="stylesheet" href="/richtexteditor/runtime/richtexteditor_preview.css" />

What is included in the base license

  • AI Toolkit — Ask AI, AI Chat and AI Review, using your own provider key. No AI add-on fee.
  • Review workflow — track changes, threaded comments and revision history.
  • Documents — tables, footnotes, pagination, legal numbering, and Word (.docx) and tagged-PDF export.
  • Real-time collaboration — per-node Yjs CRDT, self-hosted.

Competitors gate most of that behind premium tiers. The comparison pages lay out which features cost extra elsewhere, including the honest ties.
