  • Brand Radar AI, custom prompts and Content Kit are separate add-ons starting at $199, $50 and $99 a month
  • The $29 Starter plan covers search and competitive research basics rather than the full toolset

Customer.io

  • Essentials plan caps at 5,000 profiles (people and objects) and 1,000,000 monthly emails, with overages billed at $0.12 per 1,000 emails beyond that
