During my hackathon project, I built a One-Click PDF Summarizer Chrome Extension that uses OpenAI’s GPT model to automatically summarize PDFs or webpages in just one click. Through this project, I learned how Chrome extensions work — including how the manifest file, background script, content script, and popup UI communicate using message passing. I also gained hands-on experience with OpenAI API integration, asynchronous JavaScript, and handling errors like the “illegal return statement.” I implemented secure API key storage, text extraction from webpages, and dynamic API calls to generate concise summaries. This project not only improved my technical skills in JavaScript and web APIs but also gave me a deeper understanding of how AI can simplify real-world tasks by combining powerful backend intelligence with a clean, user-friendly interface.
