Every Asa plan caps how many knowledge sources Asa can have trained at once. Each trained source is one row in Manage Content — except snippets, which are unlimited and do not count.
Plan limits: 50 (Free), 250 (Starter), 500 (Growth). See Plans and pricing for the full comparison.

What counts as one knowledge source

Source typeHow it is counted
Files (PDF, DOCX, CSV, TXT)One file = one knowledge source when trained
Websites (URL)One URL = one knowledge source when trained
Shopify — ProductsOne product = one knowledge source
Shopify — BlogsOne blog article = one knowledge source
Shopify — PagesOne Online Store page = one knowledge source
Shopify — PoliciesOne store policy = one knowledge source
NotionOne selected page = one knowledge source
Google DriveOne doc or file = one knowledge source
When you select content to train, the dashboard shows how many Knowledge source(s) you are about to use — for example in the Shopify and Notion selection dialogs.

What does not count separately

These are included with the parent source, not billed as extra knowledge sources:
ItemIncluded with
Product metafieldsThe Shopify product you trained
Judge.me reviewsThe linked Shopify product
Yotpo reviewsThe linked Shopify product
Klaviyo ReviewsThe linked Shopify product
SnippetsDo not count toward your plan limit at all
Snippets are added under Add Content > Snippet. Use them for short FAQs or macros without using plan capacity. You can publish trained snippets as widget FAQs from Manage Content.

Shopify stays in sync without extra sources

When Shopify is connected, product and content updates sync via webhooks. Retraining updates the same knowledge source row — it does not create a duplicate count for the same product, page, or article.
Prefer Add Content > Apps (Shopify, Notion, Google Drive) over manual uploads when content lives there already. Integrations keep answers current with less manual re-uploading.

Check your usage

Open Billing from your account menu (or subscription settings) and find Usage Summary. Total Knowledge Sources shows trained count versus your plan limit (for example 42 / 250). If training is blocked, the dashboard explains how many sources you have left or prompts you to upgrade.
