Widget

Put an assistant on your website for your visitors, as a chat bubble, a chat inside a page or a hosted page, with the allowed domains and spending limits you choose.

A widget puts one of your assistants on your website. Visitors ask in their own words, the assistant answers from your resources and shows its sources the way you choose. Nobody needs an account.

Three formats, one chat

FormatWhat visitors seeGood for
Chat bubbleA button in a corner of every page opens the chat in a panel, full screen on phones.A website, a help center, a docs site.
In a pageThe chat sits inside a page, where you place it.A help page, a docs sidebar, a product page.
Hosted pageA page of its own on Lookio, at a link you share.An email, a QR code, a menu link. No website needed.

The three are the same chat with the same settings. Each format is on or off. A new widget starts with the chat bubble only: turn on the others in the widget’s Install tab. A format that is off does not exist: the chat bubble does not show, and the in-page chat and the hosted page answer “not found”. One widget can have several formats on at once.

How it works

  1. You create a widget in Widgets: its name, which assistant answers, and on which site.
  2. You paste one line of code on your site, or turn on the hosted page and share its link.
  3. A visitor asks. The answer streams in, with its sources. Each answer returned by the model spends the widget’s answer mode price, even if no source is found. A widget whose assistant reads no resource does not show on your site.

You stay in control of the spending: the widget only shows on the domains you allow, each visitor has an hourly and a daily limit, and you can set a monthly credit ceiling for the widget. See Access and limits.

What the widget never does

  • It never puts a key in your page. A visitor gets a short session from Lookio, valid for this widget only.
  • It never shows on a site you did not allow: browsers themselves refuse to display it elsewhere.
  • It never tells a visitor about your credits or limits. A visitor who reaches a limit is asked to come back later.
  • It never reads your page: it runs in its own frame and does not see your site’s content or cookies.
  • It never shares what a visitor did with your page. The random id behind a visitor’s past chats lives in the chat frame’s own storage, partitioned per site. Turn Visitors’ chat history off and every visit starts a fresh conversation. A widget-specific visitor proof remains for limits; retained chats become available again when history is enabled.

Query these docs via MCP

Recommended

Add this server to Claude, Claude Code, Cursor, Mistral, or any tool that supports MCP. Your agent can then search Lookio Docs documentation and read it in full, instead of answering from memory.

  • searchFind the passages that answer a question.
  • fetchRead one page in full, as Markdown.
  • list_pagesSee every page in this documentation.

Query these docs over HTTP

The same tools also work as plain web requests. Use this for scripts, or for any tool that does not support MCP. There is one endpoint per tool. Arguments go in the query string, and the answer comes back as JSON.

Read the OpenAPI description. It is built from the same definitions as the tools, so it always matches what the endpoints do.

Read these docs as Markdown

Add .md to any page URL to get its Markdown source. You can also send the headerAccept: text/markdown to the page URL itself.
