Add AI search to your website in minutes
Point the crawler at your site, get hybrid keyword + vector search and a RAG API, then plug it into your pages with a widget, a module or the REST API. No code, no OpenAI key, no servers.
What "AI site search" actually means
Classic site search matches words. AI site search also understands meaning: a visitor typing "cheap way to run search without servers" should find your "managed hosting pricing" page even though none of those words appear on it. Opensolr does this with hybrid search: BM25 keyword matching fused with vector similarity, in one query, on one index. On top of that sits a RAG API that hands the best-matching passages to an LLM so you can answer questions, not just list links.
The three steps
Give the web crawler your homepage or sitemap. It fetches pages, PDFs and documents, extracts clean text, and indexes it. JSON, CSV or the ingestion API work too.
Every document gets embeddings on Opensolr GPUs during indexing. No OpenAI key, no embedding pipeline to build, no per-token bill. Hybrid search is on by default.
Embed the search widget, install the WordPress plugin or Drupal module, or call the REST / RAG API from any stack.
Six ways to connect it
| Your stack | How |
|---|---|
| Any website | Embeddable search widget: one script tag, hybrid search and facets included. |
| WordPress / WooCommerce | WordPress Opensolr Search plugin from WordPress.org: replaces the default search, indexes posts, pages and products. |
| Drupal | Drupal Opensolr Search module, or the Search API connector if you already use Search API. |
| Python / LangChain | langchain-opensolr vector store on PyPI: use your index as the retriever in any LangChain RAG chain. |
| AI agents | MCP server: Claude, Cursor or any MCP client can search your index as a tool. |
| Everything else | REST API: ingest, search, embed and RAG endpoints with scoped API keys. |
What you get that a search box alone does not
What people search, what returns nothing, what they click.
Pin the right page to the top for the queries that matter to your business.
Field weights, synonyms, spellcheck and facets from the control panel, no redeploys.
Backups, monitoring, replication and security handled for you. Open standard, no lock-in.
How much does AI site search cost?
Plans start at €12/month billed yearly, and every plan includes the crawler, hybrid vector search, the RAG API, analytics and the modules. There is no separate "AI add-on" and no per-token embedding bill. See pricing, or compare with Algolia and Elasticsearch.
Create a live index, push a URL or JSON, watch the vectors appear, and query it with keyword, vector and hybrid search side by side.
