CONNECTIFY – A Chat Analyzer

Abstract

Connectify is a lightweight web application for analyzing WhatsApp chat exports through statistical and visual methods. Developed using Python and libraries such as Pandas, Matplotlib, Seaborn, and NLTK, the tool extracts insights from unstructured text data and presents them in an interactive dashboard. Core features include message timelines, user activity heatmaps, media/link usage statistics, and word/emoji frequency analysis. A key component is sentiment classification using the VADER model, which labels messages as positive, negative, or neutral. Additionally, a conversation flow graph visualizes message exchanges between participants. Designed for ease of use and scalability, Connectify is deployable on cloud platforms like Streamlit Cloud or Heroku, making it suitable for researchers, educators, and users exploring digital communication behavior.
