Customer support chat and AI agent

Should you build your own Intercom?

Hybrid. Build your help center and AI answers, and keep a small inbox for live chat.

HYBRID

Short answer

Intercom charges per seat, plus $0.99 every time its Fin AI agent resolves an issue, and that adds up fast. Answering questions from your own docs with an AI model is a well-known build. Live chat for a team, with routing, presence and mobile apps, is where buying still makes sense.

  • A contact form feeding a shared email inbox
  • A simple ticket list with statuses

Our estimate for AI model calls at small-business volume.

What you’d give up
