How to add an AI chatbot to Drupal
On Drupal, a chat widget is installed through The theme's html.html.twig, or the Asset Injector module. Requires a cache rebuild before the change appears. Self-hosted, so no plan gate.
Where it goes
The theme's html.html.twig, or the Asset Injector module
Availability: Self-hosted, so no plan gate.
Adding the chatbot to Drupal
- 1
Install the Asset Injector module for a UI-driven approach, or edit your theme directly.
- 2
With Asset Injector, add a new JS injector and paste the snippet's contents.
- 3
To edit the theme, open templates/html.html.twig and paste before the closing </body>.
- 4
Clear caches from Configuration → Performance.
- 5
Requires a cache rebuild before the change appears.
The snippet you paste
<script src="https://rubyrep.com/rubyrep.js" data-rubyrep="rr_your_public_key" defer></script>Your own key replaces rr_your_public_key — you get it after training RubyRep on your site.
Worth knowing on Drupal
Drupal aggressively caches rendered markup; drush cr or a cache rebuild is required.
Editing a contrib theme directly is overwritten on update — use a subtheme.

What is a website chatbot?
The term covers two very different things. Older chatbots follow scripts and break the moment a visitor phrases something unexpectedly. Modern ones retrieve from a business's own content and generate an answer, which handles arbitrary phrasing.

What is AI customer service?
AI customer service means answering customer questions with a language model rather than a person. The useful implementations are grounded in a specific business's own content; the poor ones let a general model improvise, which produces confident answers that are wrong.
