Customize the assistant

Customize how Knowledge Assistant answers in Knowledge Assistant in the dashboard. Customize its appearance in dashboard Settings or docs.json.

Assistant behavior

On the Pro plan, open Knowledge Assistant → Behavior to tailor the assistant for each site:

SettingWhat it controlsDefault
Business or product nameThe business or product the assistant representsYour docs title
Role and audienceWho the assistant helps and how it should frame its helpGeneral product support
Default toneConversational, professional, or formal wordingConversational
Default answer detailConcise answers, detail that adapts to the question, or fuller explanationsConcise
Additional instructionsWriting preferences, terminology, and support guidance in MarkdownNone

Role and audience starts with the actual default text, ready to edit. Keeping that text unchanged uses the default; saving custom wording overrides it.

Business or product name initially shows your docs title. Saving that name unchanged continues to follow your docs title; saving a custom name overrides it for the assistant’s answers. Clearing the name restores the docs title when you save. Before the first docs ingestion, the field is blank unless customized. It does not change your docs title, assistant panel header, or MCP tool labels.

For example, set the role and audience to “Help small business owners set up and use our booking software. Assume they are new to the product.” Additional instructions might look like:

## Writing preferences- Use plain language and explain unfamiliar terms.- Use numbered steps for setup instructions. ## SupportFor account-specific help, direct readers to https://example.com/support.

Additional instructions can refine the tone and detail defaults. The assistant still grounds product claims in your sources, cites supporting information, and explains specific gaps when information is missing. Put product facts and policies in Additional sources. Support links in instructions can guide readers to help; they are not evidence for product claims.

Select Save changes to apply all settings. They apply to the next question, including in existing conversations, on both your docs site and external embeds. No docs rebuild is required. Reset discards unsaved edits and restores your last saved settings.

Custom business or product names are limited to 200 characters; role and audience to 1,000 characters; additional instructions to 8,000 characters. These settings do not rename the assistant panel or change which content is searched.

Assistant appearance

Use dashboard Settings for no-code appearance controls, or configure the following settings in docs.json:

SettingWhat it controls
ButtonThe floating assistant launcher button
Navbar buttonAn optional assistant entry in the top navigation
HeadingThe heading shown inside the assistant panel
Suggested questionsUp to three starting prompts shown before a conversation begins
IconA local image used for the assistant icon

Configure in docs.json

Add an assistant object to docs.json:

{  "assistant": {    "heading": "Ask Radiant Docs",    "questions": [      "How do I publish a docs change?",      "How do I add an API reference?",      "How do I connect a custom domain?"    ],    "button": {      "size": "default",      "color": "#171717"    },    "navbarButton": {      "enabled": true,      "text": "Ask"    },    "icon": {      "src": "/favicon.svg"    }  }}

Suggested questions

Suggested questions should sound like real reader questions. They work best when they point to high-value workflows or common moments of uncertainty.

Use questions like:

  • How do I publish a dashboard edit?
  • How do I add a page to navigation?
  • How do I configure Knowledge Assistant?

Avoid vague prompts like:

  • Tell me about the docs.
  • What can you do?
  • Read more.

Assistant icon

Assistant icons must be local image files in your docs root. Use a path such as /favicon.svg or /images/assistant.png.

Do not use an Iconify name or a remote URL for the assistant icon.

Button and color behavior

The assistant button uses your docs theme by default. Set a button color when the assistant needs to stand out from the rest of the page or match a specific brand treatment.

button.size can be default or small.
