Every page of txt42.ai has a Markdown copy at its URL + `.md` (`index.md` after a URL that ends in `/`); all of them are in one file: https://txt42.ai/llms-full.txt

Txt42 installs into the editor you already have. Pick your editor for the plugin or the CDN script.

- [Editor42](https://txt42.ai/docs/install/editor42): Our free editor based on TinyMCE: the plugin or the CDN script.
- [TinyMCE](https://txt42.ai/docs/install/tinymce): The plugin or the CDN script, for TinyMCE 8, 7, 6 and 5.
- [CKEditor 5](https://txt42.ai/docs/install/ckeditor-5): Coming soon.
- [CKEditor 4](https://txt42.ai/docs/install/ckeditor-4): The plugin, for the CKEditor 4 you host.

## Already running N1ED?

Txt42 is the AI assistant of [N1ED](https://n1ed.com), and N1ED already carries it on the same plugin and the same API key. Install nothing more: put the `Txt42Chat` and `Txt42Commands` buttons on your toolbar, and the settings on this site apply there too, from the same [Dashboard](https://txt42.ai/dashboard). See [Txt42 in N1ED](https://txt42.ai/docs/install/n1ed).

## For a CMS

- [Drupal](https://txt42.ai/docs/install/drupal): Coming soon.
- [Joomla](https://txt42.ai/docs/install/joomla): Coming soon.
