What our research says

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

sensai

sensai is a straightforward way to put a trained support-and-sales agent on a small business site without writing prompts from scratch, and the message-based tiers make cost predictable. It competes in a crowded field of similar chat-widget builders, and there's no API for teams that want it embedded somewhere other than a website.

Pros

  • Trains directly on existing website pages, PDFs, and docs
  • Books demos and captures lead details inside the chat
  • Pro tier offers a choice of several current frontier models
  • Free plan needs no credit card to start

Cons

  • No public API for custom integrations
  • Storage per agent is small even on paid tiers (25 MB on Pro)
  • Company discloses no headquarters location

Which one fits

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

Choose sensai if you need

  • Small businesses wanting a trained support agent on their site
  • Teams that need lead capture and demo booking built into chat
  • Anyone who wants a 7-day trial before committing to a paid tier
