Sources per plan

A source is one file, one imported web page or one published article. Sources are counted across every knowledge base in your account.

Plan Sources Knowledge bases
Free 25 1
Starter 300 1
Growth 1,500 3
Scale 5,000 10

The Account sources tile on the Knowledge page shows how many you've used.

Imports

A sitemap import brings in up to 200 pages at a time. Each page counts as one source.

Questions and conversations

A customer's question can be up to 1,000 characters. Follow-up questions see the last six turns of the conversation, so answers stay on topic without growing expensive.
