Embed & Integrate
Custom Domain
Use your own domain for the assistant chat interface.
Overview
Custom domains let your assistant's chat interface live on your own URL (e.g., chat.yourcompany.com) instead of the default Assistant Core subdomain.
Requirements
- Pro plan or higher
- Access to your domain's DNS settings
Setup Steps
- Go to Assistant Settings → Branding
- Enter your domain in the Custom Domain field (e.g.,
chat.yourcompany.com) - DNS setup instructions will appear below — add the record to your DNS provider
DNS Configuration
Subdomain (recommended, e.g., chat.yourcompany.com):
| Type | Name | Value | TTL |
|---|---|---|---|
| CNAME | chat | cname.vercel-dns.com. | Auto |
Apex domain (e.g., myassistant.ai):
| Type | Name | Value | TTL |
|---|---|---|---|
| A | @ | 76.76.21.21 | Auto |
- Save your assistant settings
- SSL certificate is automatically provisioned by Vercel (Let's Encrypt)
DNS propagation can take up to 24–48 hours. During this time, your assistant is still accessible via its default subdomain.
A platform administrator must first add the custom domain to Vercel Dashboard → Settings → Domains before the user configures DNS.
White Labeling
With a custom domain, you can also:
- Replace the logo with your own branding in the Branding section
- Set a custom primary color
- Remove "Powered by Assistant Core" branding (Enterprise plan)
