Documentation

Everything needed to put the assistant on a site and keep it running: the snippet for every stack, the full init reference, a REST API, and the Zapier triggers.

Start here

Quick start

Three things stand between an empty bot and a working one. Most sites are answering questions the same afternoon.

1
Add your content. Point the crawler at your site in the Knowledge tab. Everything the assistant will ever say comes from what you index here, so it is worth reviewing the source list once the first crawl finishes.
2
Paste the snippet. Two lines before the closing body tag — no build step, and nothing to add to package.json. On React, Next, Vue, Svelte or Angular there is a small package instead, if you would rather import it than paste it.
3
Lock it down. Add your domains to the allow-list and set a daily cap before you publish. Both take a minute and neither can be added retrospectively to a bill.
