Unpack My Chat is a private browser-based analyzer for exported WhatsApp chats. Choose a WhatsApp ZIP or TXT export and explore reply gaps, first moves, streaks, silences, 2AM activity, repeated language and the full timeline without uploading the raw chat for analysis. It currently analyses WhatsApp exports only: it does not connect to WhatsApp, export chats for you, or analyse Telegram, Messenger or other messaging platforms.
New conversation sessions begin after more than 60 minutes of silence. A reply gap is counted only when the sender changes inside that one-hour session. The longest silence is the largest timestamp gap in the export. The parser has an automated 120,000-message stress test and does not impose a 10,000-message ceiling; the history available still depends on what WhatsApp puts in the export.
