Geweb AI Search

com/

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
