LoreSync
A private, visual way to explore the rhythm and participation in your WhatsApp and Discord chat history.
The idea
Chat exports preserve a lot of messages but make long histories hard to revisit. LoreSync turns supported exports into timelines, activity heatmaps, participant summaries, and other views people can explore directly.
What the analysis shows
Follow time
Explore message activity across days and the broader life of a conversation.
Compare participation
See participant message counts and how activity is shared across voices.
Explore the details
Move between interactive charts, heatmaps, and conversation summaries.
Privacy choices
Parsing and analysis happen in the browser. The original export stays there. People can keep an analysis in that browser or choose an account-backed cloud archive after signing in and confirming. Cloud storage contains parsed messages and analysis rather than the original export. See the LoreSync privacy notice for retention and deployment details.
Scope and limits
LoreSync supports WhatsApp plain-text .txt exports and Discord .json exports up to the current 25 MB limit. It describes activity in the export; it does not score sentiment or decide what a relationship means. The app is in early access, and no specific traffic capacity or uptime guarantee is implied.
