Will Starlit work with my companion?

Starlit joins the conversation you already have. It does not create or replace your companion.

Tell us which companion app you use so we can prioritize the right integrations.

A quick check

Does your app offer a custom connection?

Look in Settings for Apps, Connectors, Integrations, Tools, or MCP. If the app accepts a web address and opens a secure sign-in page, Starlit may work with the advanced setup guide.

Technical requirements for advanced users

  • A public remote MCP or custom connector connection
  • OAuth support for private, account-specific access
  • Permission to use tools that create card mailings

If all three are available, connect first. Starlit will confirm readiness before you pay.
