I was laid off recently, so I needed to update my knowledge to be able to pass interviews. But I’m a slow learner, and I needed to accelerate the process. So I built Tutor, an open-source local project that extracts all the concepts (using AI) from study materials (I started with books and online documentation, but recently added YouTube courses as well), creates lessons in simple language, and also tests you. It helped me tremendously to get out of my brain-freeze state.
I use it with GPT Luna and Haiku (project being local, you add whatever API provider you prefer, with your own key), and both proven smart enough and dirt cheap.
