This submission is for the Hacktoberfest Weekend Challenge, with the aim of building a study helper for a friend who struggles with Coding, Digital Logic, and Maths. The AI study helper is called BCA Study Buddy and is free to use. Users can choose the subject they need help with and the mode of learning – either step-by-step explanation in English or Hindi, or a quiz format with one question at a time and kind feedback.
The app also offers YouTube video links for visual learners on every answer. It was built entirely on a phone, without a laptop, by a BCA student in India. The app uses Gemma, an open-weight AI, with a free Google AI Studio key. Available on Streamlit Community Cloud, the app can export responses as PDF or text files. One of the friends tested the app and suggested adding a video feature for better understanding of complex topics like K-maps and logic gates.
This suggestion was implemented, and the app now includes Watch video buttons in English or Hindi to open YouTube videos related to the specific question.
