Gemini AI Creates Your HN Year in Review: An LLM Breaks Down Your Hacker News Activity

This project, built on Google’s latest Gemini AI model, creates a personalized year-in-review tool for Hacker News users. After entering a username, the system analyzes the user’s 2025 activity data to generate witty commentary and interesting statistics. It also predicts the user’s HN homepage for 2035 and creates an xkcd-style comic to depict their HN persona. The project utilizes the gemini-3-flash and gemini-3-pro-image models to ensure both the accuracy and entertainment value of the results. Through provided example links, users can see the tool in action, with cases for users like dang and myself. The author encourages readers to try the tool, share their own year-in-review, and experience the innovative power of AI technology.
