Lookio is a platform for building AI assistants that answer questions from a company's own documents. It uses retrieval-augmented generation (RAG), which means the assistant looks up relevant passages in uploaded files before replying instead of relying on general knowledge alone. Each answer comes with its sources, so a reader can check where the information came from.
The product is aimed at teams that want to put internal or customer-facing knowledge to work without building their own retrieval system. Lookio describes its assistants as reachable from an API, from MCP clients used by AI agents, and from a chat widget embedded on a website.
The homepage frames the offer in three steps: upload documents, configure an assistant, then query it or automate with it. A free account includes 100 welcome credits, which lets buyers test the quality of answers on their own files before paying anything.
Users start by uploading knowledge documents. Lookio accepts PDFs, CSVs, Markdown and text files, single webpages imported by URL, and XML sitemaps that sync a whole website in one go. For PDFs, Lookio says its technology cleans the data automatically to make it retrieval-ready.
Next, users create an assistant and configure its instructions, context and access to documents. A built-in chat lets them test their own questions on their own documents before connecting anything. A metadata system keeps outputs sourced.
Finally, the assistant is queried. Developers use an API key, and the site says this works with n8n, Make and Zapier. AI agents can use MCP and CLI access, and website owners can add the widget. Each query runs in one of four modes, which differ in response time and credit cost.
The four query modes are the most distinctive control. Eco answers in about 14 seconds for 1 credit, Flash in about 6 seconds for 3 credits, Europe in about 15 seconds for 5 credits, and Deep in about 25 seconds for 20 credits. Europe mode routes answers through Mistral, a European provider, so data is processed in Europe.
The website widget goes live with a six-line script and can be placed on public sites, Mintlify docs, authenticated customer portals and internal hubs. Owners can customize the persona and instructions, exclude sitemap pages, and add private PDFs and custom Q&As alongside public docs in what Lookio calls a hybrid knowledge base.
Safeguards include a domain allowlist, a daily question limit per widget, and separate limits per visitor, network and conversation. Lookio notes that refused questions never cost credits. Assistants can also be told to decline when an answer is not in the provided documents.

Lookio offers an API, MCP and CLI access, and a website widget. The site says it is compatible with n8n, Make and Zapier, and the widget can be added to Mintlify docs, custom portals and internal hubs.
Lookio says its assistants are grounded in the documents you provide. If an answer is not in the authorized resources, the assistant can be instructed to decline rather than make one up.
Yes. You list the domains allowed to show the widget, and each widget has a daily question limit, with further limits per visitor, network and conversation. Lookio notes that domain lists alone cannot stop direct API calls, and refused questions cost no credits.
