Background
LectureMind is an app idea that came to existence based on my struggles when reviewing lecture slides. For the longest time, when I did not understand a particular section within a lecture, I would usually take a screenshot or copy the text and paste it into an LLM (ChatGPT, Claude, Gemini). After doing this repeatedly over a few months, I realized how inefficient it really was. Constantly switching tabs and pasting became tedious, and that's where this idea came to life.
Overview
LectureMind is a mobile app that lets students upload lecture slides or notes and interact with them through a built-in chat interface. It uses a RAG pipeline to make navigating dense academic material faster, more natural, and more useful inside a single workspace.
