Thea answers only from the sources you connect. Mix types to match how your docs actually live. Open Knowledge in the server sidebar. This is not under Settings.

​
Source types

Single page

Index one URL, right now. It must be a web page or text document. Upload PDFs as files instead.

Entire site

Enter the site’s URL. Thea uses its sitemap.xml when it exists, including gzipped sitemaps and sitemap indexes. Otherwise it follows same-site links up to your plan’s crawl depth. On re-sync, only changed pages are re-embedded.

Status page

A status page that re-syncs on a schedule. Pair it with Settings → General → Status page alerts to post when an incident opens or resolves.

Upload file

PDF, Markdown, or plain text. Size limits: 2 MB (Free), 20 MB (Pro), 50 MB (Business).

FAQ

Structured question-and-answer pairs. They get a retrieval boost because they look like how members ask.

Notion

Sync the pages you share with a Notion integration. Pro and Business. Counts as one source for the whole connection.

Zendesk

Articles from a public Zendesk help center. Pro and Business.

Discord thread

Index a resolved thread so Thea can reuse an answer your team already wrote.

Help center articles

Published articles from your Thea help center are indexed automatically.

Content API

Pages you push with an API key. Pro and Business. See Content API.

​
Crawl depth

When you add an entire site without a sitemap, Thea follows links up to: Site crawls skip links to PDFs, images, archives, media, and fonts. To index a PDF, upload it as a file. Each page or sitemap Thea fetches has the same size limit as file uploads: 2 MB (Free), 20 MB (Pro), or 50 MB (Business).

Wait for Ready

Status moves through Queued, Building, Ready, or Error. Stale means a scheduled sync failed or the source changed out from under the index.
If Thea cannot read any pages from a sitemap, the source shows Error instead of indexing the sitemap file itself. Paused means scheduled syncing stopped after repeated failures. Fix the source, then choose Resume syncing from its menu. Paused sources keep serving whatever was last indexed. The dashboard warns collaborators so you do not forget a freeze.

​
Sync

Choose Re-sync from a source’s menu to fetch it now. This works for single pages, sites, status pages, and Notion or Zendesk connections. Status-page alerts post only from scheduled syncs (see Settings → General), so if a manual re-sync picks up a change first, no alert is posted for that change. A re-sync removes pages only after it reaches the whole site and confirms they are gone. If part of the site times out, is rate limited, or returns a server error, Thea keeps the pages it could not check and notes that on the source. A page that moved to a new address keeps its indexed copy.
Document and passage limits apply across all sources combined. New content stops indexing when you hit the cap. Indexing also pauses when your server reaches its monthly spend cap. This applies to site crawls, re-syncs, file uploads, integrations, and Content API pushes. Content already indexed keeps serving.

​
Credentials in your docs

Thea scans everything it indexes for values that look like credentials, such as API keys, tokens, private keys, database passwords, and lines like DB_PASSWORD=. It also catches a label and its value that sit in different table cells, paragraphs, or a heading. Thea replaces those values with a redaction marker before indexing, so answers never quote them. A source with redactions shows a credentials badge on Knowledge. This applies to every source type, including Notion, Zendesk, help-center articles, and Content API pages. Treat the badge as a published credential: rotate it, remove it from the page, then re-sync. The badge clears once no passage from that source still contains a redaction.

​
Knowledge gaps

On paid plans, Thea clusters questions it could not answer. Open the gaps from Knowledge. Each gap offers Draft article, Addressed, and Dismiss. Draft article adds a draft to your help center, so create the help center first. Drafts count toward your plan’s article limit. After you add or update a source, ask the same questions in the Playground and confirm the new passages show up before members rely on them.
