Articles & limits
What counts as a Knowledge Base Article, what each plan includes, and what happens when you reach the limit.
Your knowledge base is measured in Knowledge Base Articles. Every item you add counts as exactly one article, whatever its type:
- an article you write,
- an uploaded file (PDF, DOCX, …) — one file is one article, regardless of file size,
- a crawled web page — one page is one article.
Importing 10 URLs and uploading 3 files uses 13 articles. Your plan sets how many articles the knowledge base can hold, and you can add, edit, or remove them at any time — deleting an item frees its slot immediately. A Shopify catalog answered live uses no articles at all.
Limits by plan
| Limit | Starter | Business | Premium |
|---|---|---|---|
| Knowledge Base Articles | 300 | 1,000 | 3,000 |
Need more articles on any plan? Add +100-article blocks at $19/month each from Billing. For the full plan matrix — credits, seats, and everything else — see Plans & limits.
Your plan also sets how often each website source can re-sync — weekly on Starter, daily on Business and Premium. The frequency applies to both the auto-refresh schedule and the manual Sync button; a newly added website syncs freely for its first 24 hours while you set it up. Beyond that, website crawls run under flat operational caps that are identical on every plan — up to 2,000 pages per crawl, 30 crawl syncs per workspace per hour, 10,000 pages per day workspace-wide, and 5,000 discovered URLs in the review-pages picker — which exist to keep crawls fast and predictable, not to meter your knowledge. Each individual item can hold up to 2 MB of extracted text (far more than any normal page or document).
The usage meter
The bottom of the knowledge base sidebar shows a live meter: articles used against your plan's limit. It turns amber at 80% ("Almost full") and red at 100% ("Article limit reached"), with a shortcut to upgrade.
What happens at the limit
- Uploads and article saves that would exceed the limit are rejected with an article-limit error. Nothing partial is stored.
- Website syncs stop early: pages indexed before the limit stay, newly discovered pages are skipped, and the sync is marked incomplete — "Stopped early: knowledge base article limit reached. Upgrade your plan or add extra articles to index more pages." Pages you already have still refresh normally, and Asks emails you so a quietly truncated crawl doesn't go unnoticed.
- Existing content keeps working. The agent still answers from everything already indexed; you only lose the ability to add more.
To get back under the limit, delete items you no longer need (slots free immediately), upgrade your plan, or add an extra-articles block.
