I analysed 20 years of my chats | Hacker News

Hacker News discussed an article on analyzing 20 years of chat logs to uncover patterns in communication and behavior.

Commenters compared approaches like TF-IDF, word clouds, LLM summarization, and social-graph analysis for mining message archives.

People shared experiences exporting old data from Telegram, Signal, and even MSN Messenger, noting the value of long-term logs.

The thread also raised privacy concerns, especially around archived messages and whether bypassing disappearing-message settings is acceptable.
