Voiceflow

Voiceflow is a platform for building AI agents that can both talk on the phone and chat on the web. It started as a tool for conversation designers and has grown into a complete system that companies, from startups to large brands, use for customer support, lead generation, and their own call centers. It's for anyone who wants to build a smart agent without hiring a development team.

It works in a visual editor where you assemble the conversation flow from blocks that you simply drag and connect. The input is a customer question or call, the agent processes it according to your flow and your data, and the output is a reply by voice or text. Once it's live, you see entire conversations in dashboards, where the agent succeeded and where it stumbled, so you can keep improving it.
