WhatsApp Chat Analyser with Sentiment

Turns an exported chat file into activity stats, word clouds and mood

1-2 weeks build

Overview

Upload a chat exported from WhatsApp's own Export Chat option and the app parses every message into a timestamped table, handling both 12- and 24-hour formats. It then charts who talks most and when, builds word and emoji clouds, and scores each message with VADER so you can follow the group's mood over time. Everything runs locally and nothing is uploaded anywhere.

What makes it stand up

  • 01Regex parser for Android and iOS export formats
  • 02Per-member message, word, media and link counts
  • 03Hourly and weekday activity heatmaps
  • 04Word and emoji clouds with Hinglish stop-word filtering
  • 05VADER sentiment timeline per member and for the whole chat
