Collaborate and create with your own
AI-powered text editor

The power of AI, right inside your app

Turn your WYSIWYG into an AI-powered text editor with AI Assistant. Write, rephrase, explain, translate, and summarize content, all without leaving the editor.

  • Uses powerful OpenAI GPT models.
  • Simple plugin-based integration.
  • Fully customizable and extensible.

Give the AI Assistant a spin on the demo text! Paste your content or import from Word if you wish.

  • Use predefined prompts for enhancement on selected text.
  • Craft your own prompts open-ended or for selected text.


  • Please keep in mind that the content generated by AI Assistant may be inaccurate. To improve the responses you can write additional prompts or try again.
  • This is just an example implementation with a small subset of available CKEditor features. The way the editor looks and which features are enabled – it’s all up to you.

Choose your own AI experience

AI Assistant’s behavior and interface are customizable, with options designed for beginners and AI pros.

  • Ready-to-use optimized prompts – select your text and ask AI Assistant to change tone and style, fix grammatical errors, summarize and more.
  • Free-form prompt input – create your own more detailed prompts to generate complex custom content.

AI + collaboration = better teamwork and outcomes

Combining AI with a collaboration-first rich text editor means your team gets more done, with higher quality outcomes. Collaborate with colleagues on a document in real-time, and use the in-editor AI Assistant to craft the perfect draft.

Install AI Assistant in the same way as any CKEditor plugin. Because it is a premium plugin, you will need to provide a license key to activate the feature. You can obtain a license key either by purchasing the plugin or starting a free trial.

However, since the plugin uses the OpenAI API, you will also need the following:

  • An OpenAI API key.
  • A server-side proxy that ensures safe data transfers between your application and OpenAI (recommended for production deployment). This link requires the use of your OpenAI API key, and you will need to pay any API usage costs directly to OpenAI.

For experimenting with the AI Assistant in a test environment, there's no need to establish a server-side proxy.

For details on configuring the server-side proxy, see our guide.
