URL Preview, HyDE and Knowledge Base Upgrades

We have shipped a set of improvements that make Knowledge Base answers easier to trust, easier to debug, and easier to improve over time. One of the biggest updates is URL Preview, which lets you show a preview of the exact sources used in an AI answer, directly inside your reply.

New features

New highlight: URL Preview in Reply Action

You can now add a URL Preview section inside the Reply action, so the user sees where the answer comes from.

What it does

• Shows the source URLs used to generate the response
• Works especially well when the AI answers from your Knowledge Base and you want the conversation to stay transparent

How to enable accurate sources (JSON Sources)

To display the real URLs used by the Knowledge Base, configure it like this:

1. Open the linked Ask Knowledge Base action
2. Go to AI Settings
3. Enable Get contents sources
4. Enable Assign KB JSON Sources and set an attribute name (example: kb_json_source)
5. Go back to the Reply action
6. In URL Preview, select JSON Sources and use the same attribute

Here is the full tutorial for URL Preview

Fix included

• Fixed a bug where, if the last message was a URL preview, the UI could show buttons from the previous message.

Ask Knowledge Base: smarter retrieval options

HyDE and Use cache

We added two new options in the AI Settings modal for Ask Knowledge Base:

• HyDE (Hypothetical Document Embeddings)
  Helps retrieval by generating a “hypothetical” answer-like document that improves matching when the original user query is short or ambiguous.
• Use cache
  Reuses recent retrieval results where possible to reduce repeated calls and improve responsiveness.

These options are also reflected internally as Ask KB keys (use_hyde and use_cache).

Chunks only behavior is now clearer

When Chunks only is enabled, we made the preview behavior more consistent:

• Streaming is automatically disabled (because the output is raw chunks, not a generated answer)
• The preview shows a specific message explaining what you are seeing
• Fonts are read from the metadata returned by the response to render the output correctly

Fixes included for Ask KB

• Fixed the streaming preview not being re-enabled after disabling Use cache
• Fixed issues where Ask KB could lose the selected Knowledge Base after editing text
• Fixed incorrect display of selected template defaults and max token settings
• Fixed a default max token issue for a template (default was too low)

Knowledge Base operations and content management

Cleaner sitemap and web content handling

• When a sitemap is deleted, all content imported from that sitemap is now deleted too, keeping your KB clean and consistent.
• Web content modals were refactored to improve layout and user experience, including clearer scraping rule visibility and faster navigation.

Export questions for analysis

You can now export:

• Answered questions
• Unanswered questions

Export formats:

• CSV
• JSON

This is useful for reporting, content planning, and tracking what your AI Agents still cannot answer.

Add to Knowledge Base action fix

• Fixed an issue where content added through the “Add to Knowledge Base” action was not being saved.

Better navigation in question tables

• Added a clear navigation shortcut from answered and unanswered question tables to the related conversation.
