Brand DNA auto-detection

What gets detected

During onboarding, when you provide your URL:

  • Primary brand color. Extracted from CSS variables, header/button colors.
  • Logo. Pulled from favicon or site header.
  • Font family. Detected from CSS.
  • Tone. "Formal", "casual", "technical", "friendly" inferred from homepage copy.
  • Voice attributes. First-person vs third-person, enthusiastic vs neutral.

How it's used

Three places:

  1. Widget styling. Accent color, font family applied automatically.
  2. Hosted page. Logo and color inherited.
  3. Bot personality. System prompt seeded with detected tone.

About 70 to 85% of detections are accurate enough to use as-is.

Re-running detection

If your site changes:

  1. Workspace Settings > Brand DNA > Re-detect.
  2. Provide URL (defaults to your workspace URL).
  3. AskVault re-extracts in about 60 seconds.
  4. Review proposed changes.
  5. Accept or override.

Manual overrides

Detected values aren't locked. Override anywhere:

  • Widget Studio for colors and logo.
  • AI Config for tone.
  • Hosted page settings for layout.

Overrides preserved across re-detection.

When detection fails

Three cases:

  • JS-rendered site. Headless rendering pulls the colors but may miss CSS variables. Override manually.
  • Generic-template site. Bootstrap or other framework defaults. Specify your true brand.
  • Pre-launch site (under construction). Run detection later.

Limits

  • Re-detections per workspace per day. 10.
  • Detection latency. About 60 seconds.
  • Site requirements. Must be publicly crawlable.

Common pitfalls

Wrong color picked. Auto-detection picks the most prominent. Override to your actual brand primary.

Tone too generic. Homepage copy too vanilla. Customize the system prompt directly.

Logo blurry. Favicon too small. Upload a higher-resolution version under Widget Studio.

FAQ

Can I skip Brand DNA?

Yes. Configure widget manually. Brand DNA just saves time.

Does this read sensitive content?

No. Public homepage only. No deep crawling during this step.

How accurate is the tone detection?

About 70 to 85%. Re-check after launch and override if needed.
