MxChat AI Search

Version 1.0.3 · Updated 3 days ago

Google-style AI Overviews for your own website's search. Visitors' queries get answered straight from your knowledge base — above your theme's normal results, as a full AI results page, or anywhere on your site via an embeddable AI search box.

Features

  • AI Overview above your default search results — works with any theme's native search bar, zero theme edits. The overview renders as clean text that inherits your site's fonts and colors.
  • Full AI results page mode — a Google-style layout with the AI answer on the left, matching article cards with thumbnails on the right, and a "Show all results" link back to your classic results.
  • Embeddable search box — drop an AI-answering search input on any page with the mxchat_ai_search shortcode or the Gutenberg block. Visitors get answers in place, no page reload.
  • Grounded answers with sources — every answer is generated from your MxChat knowledge base and links the entries it drew from. Queries below the confidence threshold show nothing rather than a made-up answer.
  • Fast by design — your search page always loads instantly; the overview streams in afterward. If the AI is ever unavailable, visitors simply see your normal results.
  • Built-in caching and per-IP rate limiting protect your API bill, with a one-click cache clear and a configurable confidence threshold.
  • Multilingual-ready — every visitor-facing string (overview heading, generating message, sources label) is customizable from settings.
  • Uses your existing MxChat provider and model — OpenAI, Claude, Gemini, Grok, DeepSeek, OpenRouter, or a custom endpoint. No separate API setup.

What's new

Version 1.0.3

  • Fixed AI Overview now works on sites that keep their knowledge base in Pinecone. Previously it only ever read the WordPress database copy, so on a Pinecone site it found nothing, showed no overview at all, and gave no error or warning anywhere — the add-on looked switched on and simply did nothing. It now reads whichever knowledge base your site actually uses. Sites on the WordPress database are unaffected.
  • Fixed Source links for knowledge imported from another website now open the real external page. Previously an external address could be silently swapped for a page on your own site — often the homepage — when its path looked like a local one.
  • New A "Include external source links" setting. Turn it off to list only sources from your own site under the AI Overview; knowledge from other websites still informs the answer.
  • New An optional footer note for the AI Overview. Write your own short note — for example an accuracy reminder pointing readers to the sources — and it appears at the bottom of every overview. Supports basic links, and stays hidden when left empty.
  • Fixed AI Overviews no longer fail on sites whose MxChat model is GPT-5.4 Mini or GPT-5.4 Nano. The reasoning setting sent to these two models was never accepted by them, so the search overlay silently showed no overview at all. Overviews also now recover automatically if a model rejects a reasoning setting in the future, retrying once without it. Requires the matching MxChat core update for the full fix.
