Customer support AI agent builders

By César Murga · 8 tools

Customer support agent builders create chat or voice agents that answer and resolve customer questions. Botpress prices per conversation from $150 per month with AI usage included; Voiceflow suits CX teams and agencies with usage-based billing and white-labeling.

The main questions here are channel coverage (web chat, WhatsApp, phone), how a “conversation” or “resolution” is billed, and whether the agent can take real actions such as refunds or account updates.
