Geweb AI Search transforms your WordPress search into an intelligent assistant powered by Google Gemini AI. Instead of returning a plain list of matching posts, it understands the user’s question and provides a direct, contextual answer — along with links to the source pages.

The plugin intercepts the standard WordPress search form and opens a modal with two modes: instant autocomplete suggestions (via WP_Query) and a full AI chat powered by Google Gemini File Search.

Key Features

AI-Powered Answers — Uses Google Gemini File Search to find relevant content and generate natural-language answers
Conversation History — Users can ask follow-up questions; the context is maintained across the session
Source Attribution — Every AI answer includes links to the pages it was based on
Instant Autocomplete — Traditional keyword search with live suggestions while typing
Automatic Indexing — Posts are automatically uploaded to Gemini when published or updated
Bulk Library Generation — Index all existing content with one click and a live progress indicator
Multiple AI Models — Choose between Gemini 2.5 Flash, 2.5 Pro, and Gemini 3 models
Multiple Post Types — Index any public post type: posts, pages, or custom post types
Secure API Key Storage — API key is encrypted with libsodium before being stored in the database

How It Works

The plugin converts your WordPress posts to Markdown format (with URL and title in frontmatter)
Each document is uploaded to a Google Gemini File Search Store
When a user submits a search query, Gemini searches the indexed documents and generates an answer
The answer is displayed in a chat modal along with source links
