Knowledge sources are the content your agent draws answers from. The more relevant and well-structured your sources are, the better your agent performs. You’ll find them under Knowledge in the sidebar.
Access: Adding, editing, and deleting sources requires Editor or Owner access. Viewers can browse the list but can’t make changes.

Source types

Klaro supports three ways to feed content to your agent:
TypeBest for
WebsitesProduct pages, help centers, FAQs, blog posts - anything publicly accessible by URL
PDFsDocumentation, manuals, whitepapers, anything that lives in a file
TextShort reference content, internal FAQs, policies - anything you want to paste in directly
Each source type is indexed separately but queried together when a visitor asks a question.

Status lifecycle

After you add a source, Klaro processes it in the background. You can watch the status update in real time - no need to refresh.

Website

pending → crawling → indexing → completed → failed
  • Pending: source created, waiting to be picked up
  • Crawling: Klaro is fetching the page content from the URL
  • Indexing: content has been retrieved and is being split into chunks and embedded
  • Completed: source is live and searchable
  • Failed: something went wrong at one of the steps (bad URL, unreachable page, etc.)

PDF

pending → indexing → completed → failed
PDFs skip the crawling step - once uploaded, they go straight to indexing.

Text

indexing → completed → failed
Text sources start indexing immediately on creation.
If a source shows “failed”: the most common reasons are a URL that requires login, a PDF that’s too large or too long, or a text source that exceeded the word limit. Fix the issue and re-add the source (or re-scrape for websites).

Adding knowledge sources

Website

You have three ways to add website content: Single - paste one URL and submit. Good for a specific page you know you want indexed. Multiple - paste up to 10 URLs, one per line. Use this when you have a list of pages ready to go. Crawl - enter a base URL and Klaro maps the site, showing you up to 30 discovered pages. Pick the ones you want (up to 10 at a time) and add them in one go. This is the most efficient way to index an existing help center or documentation site. URLs are normalized before saving - you can paste with or without https:// and trailing slashes, Klaro handles it.

PDF

Click + Add Document, then drag and drop your file or click to browse. One file per upload. Constraints:
  • Format: PDF only
  • Max size: 10 MB
  • Max pages: 50 pages
The title defaults to the filename (without .pdf). You can’t rename it after upload - if you need a different title, delete and re-upload.

Text

Click Add Text Source, enter a title and paste your content. The title must be unique per agent - adding two text sources with the same title will fail. Constraints:
  • Max: 10,000 words
  • A live word counter shows your current count as you type; the submit button disables when you go over
Text sources are useful for internal knowledge that isn’t published anywhere - things like escalation procedures, pricing tiers, or product positioning notes that you want the agent to know but don’t live on your website.

Re-scraping websites

Websites can be manually re-scraped to pick up updated content. Find the source in the list and click Re-scrape. A few things to know:
  • Re-scraping counts against your monthly website scraping limit (same as adding a new website)
  • You can’t re-scrape while a source is currently being crawled or indexed - the button is disabled during processing
  • When a re-scrape completes, the old content is fully replaced - not merged
PDFs and text sources don’t have a re-index option. If the content changes, delete the source and re-add it.

Deleting sources

You can delete any source from the list. Deletion is permanent and immediate - the source is removed from the index and your agent will no longer use it for answers

Plan limits

Two limits apply to knowledge sources, and both are scoped to your workspace: Total knowledge sources - the combined count of all source types across all your agents. Once you hit the limit, you’ll need to delete existing sources or upgrade your plan to add more. Website scrapes per month - counts both new websites added and re-scrapes of existing ones. Resets at the start of each billing month.

You can see your current usage directly on the Knowledge Sources page. If you hit a limit mid-workflow, you’ll see an inline error message with your current counts - head to Settings → Billing to review your plan.
