What does Jovo do?

Jovo is an open-source framework that helps developers build conversational apps that work across multiple voice and chat platforms. Instead of maintaining separate codebases for Amazon Alexa, Google Assistant, Facebook Messenger, and web interfaces, you write your app logic once using Jovo's component-based API. The framework handles the platform-specific translations, letting you focus on the core functionality of your voice or chat application.

The framework uses TypeScript for strong typing and developer-friendly autocompletion. It follows a declarative approach similar to React, where you define handlers and compose components. Jovo includes a local debugging environment with visual tools to test your apps, and it supports plugin integrations with various natural language understanding services like Dialogflow, Rasa, and Lex, as well as content management systems.

Jovo works best for developers building complex voice and chat applications that need to reach users on multiple platforms. It's particularly useful for teams creating enterprise-grade voice assistants, customer service chatbots, or interactive voice applications that require custom backend logic and integrations. The open-source nature means you can use it freely for commercial projects without vendor lock-in.
