Echo Knowledge Base supports two AI Providers:

  • OpenAI ChatGPT
  • Google Gemini

You can switch between them at any time, but some reconfiguration is required because each provider stores training data in its own vector store.

Key terms:

  • AI Provider — the AI service used for AI Search, AI Chat, and Training Data.
  • Data Collection — a provider-specific set of content sent to the AI Provider. AI Search and AI Chat can only use Data Collections belonging to the active provider.

What changes when you switch:

  • Data Collections are provider-specific and do not transfer.
  • Only the active provider’s collections appear in AI Search and AI Chat. Collections from the other provider are preserved and reappear if you switch back.
  • AI Chat’s selected collection, and AI Search’s KB-to-collection mappings, may need to be re-assigned.

The steps below walk you through getting AI Search and AI Chat working again on the new provider.

Step

Enter the API Key for the New Provider

- Go to AI Features → General Settings
- Paste your API key for the newly selected provider (OpenAI ChatGPT or Google Gemini)
- Accept the AI disclaimer
- Save settings

Step

Create a Training Data Collection (optional)

Go to the Training Data tab. Only collections belonging to the active provider are shown — any collections from the other provider are preserved but hidden until you switch
back.

If you already have a collection for this provider, skip to step 4.

Otherwise, create a new collection and continue to step 3.

Step

Add Content to the New Collection

#3 - In the Training Data tab, select the articles, pages, FAQs, or other content you want the AI to use
#4 - Sync the content to the new provider's AI storage (vector store)
- Wait for all items to show as Synced

Step

Reconfigure AI Chat (if used)

#2 - Go to the AI Chat tab

#3 - Set AI Chat Mode to Preview (admins only) or On (public)

#4 - Review Display Mode (Show Everywhere / Only Show On / Don't Show On)

#5 - In the collection dropdown, select the Training Data Collection for the new provider

#6 - Access Mode for frontend access

Save settings and test the chat on your site

Step

Reconfigure AI Search (if used)

#1 - Go to the AI Search tab

#2 - Set AI Search to Preview or On

#2 - Start with Simple Mode or use Smart Search

#3 - Under Select Training Data for Each KB, re-map each Knowledge Base to a collection that belongs to the new provider (same provider-mismatch warning applies)

Save settings and verify search works on the frontend.

Step

Verify and Monitor

On the frontend, run a few test queries in both Chat and Search to confirm answers are coming from the new provider

Notes on switching back and forth

  • Collections are provider-specific and never transfer between providers — each provider maintains its own vector store.
  • When you switch back to a previously-used provider, its collections and KB mappings are restored automatically; you generally won’t need to re-map anything you set up before, only re-sync content that has changed since.
  • If you don’t plan to switch back, you can delete unused collections to keep the list clean (switch to that provider first to see them).
