We are starting with a very simple version 1.0 where we let you search StackOverflow and public code on GitHub. Devbook is a desktop app that works similarly to Spotlight on macOS. You hit a shortcut, a window appears and you can start typing. We built the first version with developers' productivity in mind. You can control the whole app without touching the mouse. Our goal with the first version was to minimize context switching you as a developer need to do when looking for basic information on the internet.
In the near future, we plan to add more integrations in which you can search and more features focused on improving customizability and general user experience.
The app is free right now. In the future, we will introduce a subscription plan. But we would like to always offer a free plan. Also, to fully use the app, you don't need to sign up.
Currently, we support only macOS. Happy to answer any question.
