How it works, step-by-step: Prepare Your Data: Create a CSV file with three columns: userid, signupmonth (in YYYY-MM format), and activemonth (in YYYY-MM format). Upload the CSV: Click the file input button and select your CSV file. The application will instantly parse the data. Analyze the Heatmap: The main view displays a cohort retention matrix where rows represent user cohorts by signup month and columns represent activity over subsequent months (M0, M1, etc.). The full version stays on the original page, which this listing opens directly.
