Everything your chat says without you noticing
Months of conversation hold patterns you can't see while you're living them. This one turns them into numbers.
- Who talks the most. Messages, words and media per person.
- Who replies fastest. Each person's response times, and the hour of the day they get shorter.
- Who starts the conversations. How many times each one breaks the ice after a silence.
- What hours they live at. Activity map by day and by hour.
- How they laugh. How much, who most, and how long.
- The usual words. What they repeat the most, and the emojis that define the conversation.
Your chat is never uploaded anywhere
There is no server. The file is processed inside your browser and never leaves your device. We don't ask for an account, we don't store anything, we don't see your messages. You can disconnect from the internet after the page loads and it will keep working just the same — try it.
Is it safe to upload your chat?In three steps
- Export the chat. In WhatsApp: open the conversation → menu → Export chat → Without media. You get a .txt.
- Upload it here. Drag it in or tap the button. It takes a few seconds.
- Look at what came out. And if you want, share the summary card.
