Chatalytics Pro
Forensic-depth WhatsApp analysis. Zero data leaves your device.
Why It Exists
The ultimate privacy-focused WhatsApp chat analyzer: decode your chat history with interactive visualizations and zero data collection. Every byte of processing happens client-side in your browser. Underneath the real sentiment and activity analysis, it's also just fun: who leaves who on read, who starts every conversation, and how many novels you could've written with your total word count.
Client-Side Only
All analysis happens directly in your browser - your .txt/.zip export never leaves your device.
Ghost Score & The Instigator
Average reply-time analysis, and a breakdown of who initiates conversations after long silences.
Peak Activity Matrix
A heat-map bubble chart showing exactly when you talk the most, day vs. hour.
Novelist Mode
See how many novels you could have written with your chat's total word count.
