What is Dialogflow Conversational AI?

Dialogflow is Google's conversational AI platform for building chatbots and voice agents. It uses natural language processing to understand user intent and generate appropriate responses, with recent versions powered by Google's Gemini model for improved language understanding. The tool is designed for developers and businesses who need to create customer service bots, internal assistants, or conversational interfaces without building everything from scratch. You can build agents through a visual interface or via API, then deploy them across messaging platforms, websites, or voice channels. Dialogflow handles the complexity of intent recognition and context management, allowing you to focus on defining what your agent should do rather than the underlying NLP mechanics.
