Why RichTextEditor

An editor can only ask your server to store a file. What makes a site safe happens on the server, so we show you that part too, for every platform the editor supports.

Uploads checked on your server

Pictures go to your own endpoint. The guides show the checks for each platform: allowed extensions, the file’s real bytes, size limits, and paths that stay inside the upload folder. Upload security guides

An image gallery of your own folders

Users browse server folders, create new ones and upload into the open folder, then insert a picture. One JSON endpoint, written once for your platform. Image gallery guides

One editor for every stack

React, Vue, Angular, Next.js, Svelte, Blazor, ASP.NET Core, MVC 5, Web Forms and PHP. The same editor and the same browser code everywhere. Quick start

AI with your own provider

Proofread, rewrite, summarize and chat in the editor. Keys stay on your server; usage is billed by the provider you choose. AI demo

Paste from Word without the mess

Headings, lists, tables and images survive a paste from Word or Excel. The clutter does not, and the HTML you save stays clean. Paste demo

Review and write together

Comments, track changes, mentions and real-time collaboration for teams that edit the same document. All features

It fits how your stack already works

The browser side is the same everywhere. The server side is a few routes in the framework you already use, written the way that framework expects.

  • Express and Next.js route handlers for JavaScript, React, Vue and Angular apps
  • Plain PHP 8 scripts, with the Apache and nginx rules that keep uploads from running
  • ASP.NET Core controllers, minimal APIs, Razor Pages and Blazor
  • MVC 5 controllers and Web Forms handlers for .NET Framework sites

One problem per page: how to add it, what the server must check, and what to watch out for.

Questions

Is RichTextEditor a subscription?

No. You pay once and keep using your licensed version for as long as you need it. One year of updates is included; future updates are optional. See pricing.

Which frameworks does it work with?

JavaScript, React, Next.js, Vue, Angular, Svelte, Blazor, ASP.NET Core, ASP.NET MVC, Web Forms and PHP. Each has a short quick start guide, and the guides have tested server code for uploads and the gallery.

Where do uploaded images go?

To your server, through an endpoint you control. Nothing is sent to us. The guides show the endpoint for each platform, with the checks it needs.

Can I use my own AI provider?

Yes. The AI Toolkit connects to the provider you configure. AI provider usage is billed by that provider, separately from your license. Try the AI demo.

Does it handle paste from Word and Excel?

Yes. Word and Excel paste is cleaned up into tidy HTML, with tables and images kept. See the paste demo.
