Assistant context sources let Ask AI answer from approved material outside your published docs pages. Use them for product pages, support guidance, policy details, launch notes, and other information that helps the assistant answer reader questions accurately.
Context sources are available on Pro plans.
Source types
| Source type | Best for | Avoid using it for |
|---|---|---|
| Web pages | Public marketing pages, product pages, changelogs, support pages, or other web content | Private pages, localhost URLs, or internal systems |
| Custom notes | Support policy, product positioning, launch details, escalation guidance, or concise facts that do not belong on a public docs page | Long duplicate copies of docs pages |
Published docs pages and API reference pages are indexed from your docs site. You do not need to add them again as context sources.
Add a web page
Open Assistant
In the Radiant dashboard, open the Assistant page for your docs project.
Add a public URL
In the Web pages section, add a public http:// or https:// URL.
Radiant blocks local, private, and internal hostnames because assistant context sources must be safe for hosted processing.
Wait for processing
The page shows Processing while Radiant fetches and prepares the content. When it shows Available, Ask AI can use the latest processed version.
Add a custom note
Use custom notes for information that should help the assistant answer, but does not need a full public docs page.
Open Assistant
In the Radiant dashboard, open the Assistant page.
Create the note
In the Custom notes section, add a title and the note content.
Titles can be up to 120 characters. Note content can be up to 50,000 characters.
Let the note process
The note shows Processing while Radiant prepares it. When it shows Available, Ask AI can use it in answers.
Status labels
- Processing means Radiant is preparing the source.
- Available means Ask AI can use the latest processed version.
- Failed means the source could not be prepared.
If an update fails after a source was previously available, Ask AI can continue using the last available version while you retry or edit the source.
What belongs in custom notes
Good custom notes are concise and specific. They often answer questions like:
- What should support say when a user asks about an unavailable feature?
- Which plan is required for a feature?
- What product positioning should the assistant use?
- What terminology should the assistant prefer?
- Where should the assistant send users when it cannot answer from docs?
