> Source: https://theagentsindex.com/category/conversational-agent-builders (curated, re-verified)

Builders for chat and support agents: flows, knowledge, channels and handoff to a person.

3 agents in this category, ranked by what we can confirm about each (a public price, an API and docs, independent sources, stated limits; payment never changes the order). Each name links to its answer-first markdown twin.
