AI conversational-support agents that autonomously resolve customer conversations across chat, email, voice and messaging. Distinct from the manual Customer Support helpdesk tools (Zendesk, Intercom, etc.): here the AI is the front line. We evaluate the free or trial tier, how the bill scales (per conversation, per resolution or per seat), multi-channel deployment, human-takeover handoff, and whether the platform is no-code, developer-oriented or enterprise-quoted.

When you compare Conversational AI tools, the fields that decide the outcome are the ones this index actually stores: whether a free plan exists and what it limits, the published entry price and how it bills (per seat, per month, per workspace), what the trial covers, which of the six index dimensions the tool scores on, when each figure was last checked against the official page, and which alternatives sit in the same category. Each tool page prints those fields with its own verification date, the Conversational AI comparison pages put two products side by side on the same fields, and the list pages rank the category against the rest of the index — so you can move from a shortlist to a decision without opening a vendor's sales page.
