What our research says

Deacon

Deacon's answers-only-from-your-content approach and human handoff address the common complaint about support bots inventing answers, and the no-overage pricing means costs are predictable even at the limit. It is a young, small UK company, so confirm data handling and uptime directly before committing to an annual plan, and note that the $40 headline is the yearly rate.

Pros

  • Restricts answers to crawled content and uploaded files rather than the open internet
  • Includes proactive onboarding guidance, not just reactive Q&A
  • No-overage pricing means the bill is predictable even past the plan limit
  • Free tier requires no credit card to start

Cons

  • Small, young UK company with little public track record
  • Free tier's 50-answer monthly cap is low for any product with real traffic
  • The $40 headline needs yearly billing; month-to-month Starter is $50

Fin

Fin is the most mature of the per-resolution support agents, with three years of production use and the tooling, simulations, regression tests, QA, that teams need before letting an agent touch refunds. The $0.99-per-outcome model is attractive when deflection is high and unattractive when the agent resolves little, and the definition of an outcome is what you negotiate over. Running it on Zendesk or Salesforce avoids Intercom's seat fees but imposes a 50-outcome monthly floor; small support teams with a few hundred tickets a month should model both before signing.

Pros

  • Pays per resolved outcome rather than per seat, with a published $0.99 rate (15 October 2026)
  • Works on Intercom and on Salesforce, Zendesk, HubSpot and Freshdesk
  • Can act through Procedures, APIs, data connectors and MCP, not only answer
  • Simulation, regression testing, QA and observability tools before and after changes go live
  • 14-day trial with unlimited outcomes and no card

Cons

  • Outcome definitions and the $9.99 qualification charge make the effective price harder to model than a seat fee
  • 50-outcome monthly minimum when used with a third-party helpdesk
  • Operator, Copilot and Voice are separate charges on top of the per-outcome rate
  • Company rebrand from Intercom to Fin in 2026 means documentation and contracts still carry both names

Which one fits

Choose Deacon if you need

  • Products wanting a support widget that won't answer from outside the crawled content
  • Teams wanting proactive onboarding guidance bundled with support, not just reactive Q&A

Choose Fin if you need

  • Support teams with a large, well-maintained help centre where deflection can reach the levels the per-outcome price assumes
  • Companies already on Intercom, or on Zendesk, Salesforce, HubSpot or Freshdesk that want an agent without switching helpdesk
  • Teams that need the agent to take actions, such as refunds or account changes, through APIs and MCP
