Well it's not exactly a startup idea but something that I and my team built during my first-ever hackathon.
The theme was to build some tools for developers to improve their speed and be more productive.
In our team we were some bunch of students who just knew how to build a basic front end and a little bit of backend and we came up with an application that lets developer query any command line shortcut through his voice and the website will return the keyboard shortcut for that. For example the developer can ask what is the shortcut for splitting the view into two halves in vs code and the website will look it up in database and give back the shortcut
Now when I look back it feels so funny. I still remember that the judges gave us a funny look but they appreciated our efforts as we were too young to be there.. lol
btw If anyone is curious about the project it is present here ..
