By Helpdesk: Which Vendors to Evaluate
Zendesk
Intercom Fin is the most commonly deployed third-party AI on Zendesk. It installs from the Zendesk Marketplace, creates tickets natively, and handles escalations within the Zendesk UI. Ada, Forethought, and Sierra also offer native Zendesk apps. For pure Zendesk shops wanting the native AI, Zendesk AI (Resolve) is the deepest integration -- but it only works within Zendesk.
Salesforce Service Cloud
Salesforce Agentforce is native and deepest for Salesforce shops. Intercom Fin offers a Salesforce connector that creates cases in Service Cloud and syncs resolution status. For teams that want a non-Salesforce-owned AI on top of Salesforce SC (pricing flexibility, vendor diversity), Fin and Decagon are the most common options.
Intercom
Intercom Fin is Intercom's own AI agent. It integrates natively with Intercom Inbox at the deepest level. Other vendors have API connectivity to Intercom but no native integration. If you are an Intercom shop, Fin is the only first-class option.
HubSpot Service Hub
HubSpot Breeze Customer Agent is HubSpot's own AI. At $0.50/resolved conversation (updated April 2026), it is the natural choice for HubSpot-native shops. Intercom Fin has an API connector for HubSpot but lacks deep native UI integration. Tidio also connects via API for HubSpot users who want a separate chat platform.
Freshdesk
Freshdesk Freddy AI is native to Freshdesk (it is Freshworks' own product). Intercom Fin has a Freshdesk integration via the Freshworks Marketplace. For pure Freshdesk shops, Freddy is the default. Fin is worth evaluating if you want multi-helpdesk capability or per-resolution pricing on the Freshdesk conversation stream.

Common Questions
Which AI customer service agents work with Zendesk?
Intercom Fin, Sierra, Ada CX, and Forethought all offer native Zendesk integrations. Decagon and Cognigy connect via API. Salesforce Agentforce, HubSpot Breeze, Freshdesk Freddy, Tidio, and Kustomer do not have meaningful Zendesk integration -- their AI is tied to their own platforms. For Zendesk shops, Intercom Fin is the most commonly deployed third-party AI agent.
Which AI customer service agents work with Salesforce Service Cloud?
Salesforce Agentforce is native (it is Salesforce's own product). Intercom Fin has a Service Cloud connector. Decagon, Sierra, Ada, and Cognigy connect via API. For Salesforce shops, Agentforce is the obvious first choice, but Intercom Fin is commonly deployed as a second-source AI on top of Salesforce SC for teams that want pricing flexibility.
Which AI customer service agents work with HubSpot?
HubSpot Breeze is native to HubSpot Service Hub. Intercom Fin offers an API connector for HubSpot. Tidio connects via API. For HubSpot-native shops, Breeze at $0.50/resolved conversation (updated April 2026) is the clear first choice. Fin is worth evaluating as a second-source option if HubSpot Breeze's channel coverage is insufficient.
What is the difference between a native integration and an API integration for AI agents?
A native integration means the AI agent vendor has built a dedicated connector that installs from the helpdesk's app marketplace. It typically includes automatic ticket creation, status sync, escalation workflows, and reporting inside the helpdesk UI. An API integration means the connection is built via REST API or webhook -- it can do most of the same things, but requires development time to set up and maintain, and may lack some UI-level features like native reporting.
