Facebook Messenger Chat Analyzer (Free)
Drop your Messenger JSON file below for free counts in your browser: who texts more, who replies faster, who starts. Want the AI read of interest? Get the free preview.
Your chat never leaves your browser. Everything is counted on this page; the chat is never uploaded, saved or sent to any server.
How to get a Messenger chat as a file
Facebook lets you download your information from Accounts Center. Choose Messages, pick JSON as the format (not HTML) and skip photos and videos. When the download is ready, unzip it and open the folder named after your crush: the message_1.json inside is the file you need.
Many Messenger chats are now end-to-end encrypted. Messenger keeps those in a separate download on a computer (Messenger settings → Privacy & safety → End-to-end encrypted chats → Message storage). Menu names change, so follow Messenger's current screens. If the free tool cannot read a file, add screenshots on the home page instead.

Tips for a better result
Use a one-to-one chat, not a group: the analysis compares two people.
Long chats give more detail: Facebook may split one chat into message_1.json, message_2.json and so on. Start with message_1.json, which holds the newest messages.
Crush Analyzer gives an AI read of your chat, made for fun and reflection. It is not a guarantee of how anyone feels, and it cannot read minds. Use it as one more point of view, not as a verdict. See also our Privacy Policy.
