Pros and cons

Fin

Pros

  • Outcome-based pricing at $0.99 means no per-seat fee for Fin itself on non-Intercom helpdesks.
  • Works with existing helpdesks (Salesforce, Zendesk, HubSpot, Freshdesk) as well as Intercom.
  • Procedures can take actions such as refunds and account updates, not only answer questions.
  • 14-day free trial with unlimited outcomes and no credit card.
  • Broad connector list plus MCP and REST API options.
  • Simulations and regression testing let teams check changes before release.

Cons

  • Costs scale with resolved volume, so spend is harder to predict than a flat subscription.
  • Operator, CX Score and Monitors need the Pro add-on from $100 per month; Fin Voice is sales-only with custom pricing.
  • The non-Intercom plan has a 50 outcome per month minimum.
  • The Fin API Platform is limited to customers with $250k or more annual spend, and custom API integrations require a Professional or Enterprise plan.

Plain

Pros

  • Built around B2B support, with Slack, Teams and Discord channels alongside email and chat.
  • Ari and Sidekick AI agents are included from the entry plan.
  • API-first design allows custom workflows and embedding.
  • 7-day trial without a credit card, plus a 50% startup discount.
  • Enterprise options include SSO, SCIM and HIPAA on the Frontier plan.

Cons

  • No permanently free plan; paid plans start at $45 per user per month.
  • AI usage is metered in credits (1,000 per month on Foundation), which makes costs harder to predict.
  • Microsoft Teams and CRM integrations require the $99 Horizon plan.
  • No iOS or Android app was found.
