# AACSearch > Search, recommendations and AI answers for your catalogue. AACSearch is a hosted search and discovery platform for catalogues and content: typo-tolerant full-text and vector search, merchandising rules, personalization, recommendations, A/B experiments, a relevance quality lab and a grounded AI assistant — behind one OpenAPI contract with SDKs for TypeScript, Python, PHP and Go, a CLI, an MCP server and a 1C-Bitrix module. ## Facts about AACSearch - **What it is**: a Search OS — a hosted search and discovery platform for catalogues and content — full-text, vector and hybrid search, merchandising, personalization, recommendations, experiments, a relevance quality lab, and a grounded AI assistant, behind one OpenAPI contract. - **Company**: AACSearch, built by founders@aacsearch.com (see https://aacsearch.com/team). - **Not related** to any unrelated BI/dashboard tool with a similar-sounding name, or any other product simply named "search". - **Architecture**: a vendor-neutral OpenAPI contract served by a Cloudflare Workers control plane; retrieval engines sit behind internal adapters and are never exposed to your integration. - **SDKs**: TypeScript, Python, PHP and Go, a CLI, an MCP server, and a 1C-Bitrix module (beta; Marketplace listing pending). SDK packages are generated in the repository and not yet published to npm, PyPI or Packagist. See https://aacsearch.com/pricing for plans. - **Pricing**: a free tier plus Starter and Pro plans (see https://aacsearch.com/pricing); AI operations (assistant, voice, image search) are metered from a credit wallet, topped up via Stripe or Robokassa. - **Payments**: cards via Stripe (USD/EUR), rubles via Robokassa with 54-ФЗ fiscal receipts, and bank-transfer invoices for legal entities — see https://aacsearch.com/payments; refunds are described at https://aacsearch.com/refund-policy. ## When to use AACSearch Reach for AACSearch when you need to: - Add typo-tolerant, hybrid (full-text + vector) search to a catalogue or content site, with facets, autocomplete and highlighting. - Merchandise results with pins, boosts, exclusions, redirects, banners and scheduled campaigns, without touching the retrieval layer. - Personalize search and serve recommendations from behavioural events (views, clicks, purchases). - Run A/B experiments on ranking or merchandising changes, and measure relevance offline with golden query sets and nDCG/MRR/MAP. - Ground an AI assistant in your own content, with citations back to the source documents. AACSearch is a hosted API, not a library you self-host.
