Jovo

In plain words

Jovo is an open-source framework for building voice and chat applications across multiple platforms including Amazon Alexa, Google Assistant, and the web. Developers write a single TypeScript codebase that the framework automatically translates for each platform, eliminating the need to maintain separate code. It includes analytics and database integrations and uses a component-based API similar to React for defining conversational handlers.

Jovo is the open-source web framework that lets you build scalable conversational apps for Amazon Alexa, Google Assistant, Messenger, and the Web from a single codebase. Jovo is a Document-Object Mapper for voice platforms (think of Express.js , but for conversational interfaces). It uses a declarative, component-based API similar to React: you define handlers, compose components, and let the framework handle platform-specific translation.

It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
