Best AI agents for customer service
AI agents that resolve support conversations on their own, compared on what each resolution costs and what sits behind the answers.
Per-resolution billing is now the norm for support AI, but each vendor defines a resolution differently. Intercom counts an outcome when the customer confirms or stops asking; Zendesk counts an automated resolution with no escalation; HubSpot charges credits per resolution. Read the definitions on each provider page before comparing raw prices.
| Tool | Price | Unit |
|---|---|---|
| HubSpot Breeze Customer Agent | $0.50 | per resolution (50 credits at $10 per 1,000) |
| Freshchat (Freddy AI) | $0.49 | per AI session ($49 per 100) |
| Intercom Fin | $0.99 | per Fin outcome |
| Gorgias | $1.50 | per AI Agent interaction above the included allowance ($0.90 to $1.00 on Gorgias's AI pricing) |
| Zendesk AI agents | $2.00 | per automated resolution, pay as you go ($1.50 committed) |

Estimates are our arithmetic on published list prices in each tool's own currency, for one human seat and 50 conversations a month handled by AI. Where a tool bills per resolution or outcome we count every AI conversation as billable, so treat those figures as a ceiling. Setup fees and add-ons are not in the estimate and are listed beside it. Featured listings, if any, sit above the numbered rows, are labelled and never take a rank number. Full working: methodology.
The tools in brief
Tidio (Lyro)
Small businesses and Shopify stores. The cheapest paid route to a monthly AI quota in this comparison, and Lyro can be bought without a paid helpdesk plan.
Watch out for: three separate meters (human conversations, Lyro conversations, Flows visitors) to keep track of.
Gorgias
Shopify stores with order-status and returns questions. Deep Shopify order actions.
Watch out for: every AI interaction is charged and also counts as a ticket.
Freshchat (Freddy AI)
Small teams that want an omnichannel inbox at a low seat price. A free tier for up to 10 agents and low paid seats.
Watch out for: aI sessions are a separate purchase on top of seats.
Intercom Fin
Funded SaaS and mid-sized support teams that want the most capable AI agent and can model per-outcome costs. Intercom publishes a 76% average resolution rate across 12,000+ customers (vendor figure, not independently tested).
Watch out for: two meters, seats and outcomes, so the monthly bill moves with volume.
HubSpot Breeze Customer Agent
Businesses that already run sales or service in HubSpot. The lowest published price per AI resolution we found ($0.50).
Watch out for: only good value if you are already paying for HubSpot.
Zendesk AI agents
Support teams already running on Zendesk. Mature ticketing, routing and reporting around the AI agent.
Watch out for: the highest pay-as-you-go price per resolution in this comparison.
Ada
Large companies with a procurement process. A long enterprise track record.
Watch out for: out of reach for small businesses.
Lindy
Small teams automating inbox and admin work. Covers far more than customer chat.
Watch out for: less suited to a customer-facing website widget.
Sierra
Large consumer brands. Sierra reports more than $400M in annual recurring revenue (October 2026).
Watch out for: no small-business offer.
Voiceflow
Teams building chat and voice agents together. No lock-in to one model provider, and voice support.
Watch out for: no plan prices on its own website.
