FAQ
Frequently asked questions
Which AI agent is best for customer support?
Fin is our top pick at 4.4/5. Password resets, order status, plan changes, how-do-I questions — the bulk of most support queues.
Can an AI agent handle customer support without supervision?
It depends on the agent and the stakes. 7 of the 11 agents here run fully autonomously; the rest keep a human in the loop. For anything customer-facing or irreversible, start with an approval step and remove it only once you have watched enough output to trust it.
Do I need engineers to set this up?
Not necessarily. Fin is cloud-hosted and configurable without code. Self-hosted and framework options in this list do require engineering time, but give you more control and lower per-run cost.
What does it cost to automate customer support?
Entry pricing across these 11 agents ranges from free tiers to enterprise contracts. The bigger variable is the pricing model — per-seat costs are predictable, while credit- and consumption-based pricing scales with how much work you actually give the agent. Model your expected run volume before committing to an annual plan.
