Jennifer says

Visualizing my friends chat revealed a lot about our relationship. I always though that I was the one sending more messages. Really nice to see all those fun facts about our history. Keep it going and add more beautiful visuals.

Lara says

Amazing to see a whole WhatsApp history at a glance. I have chats going back multiple years seeing how the relationship is mirrored in the chat is amazing. I love that my files are not uploaded and that it runs directly in my browser.

About us
We are a group of university friends. As we recently all left WhatsApp and wanted to analyse how or chats evolved over the years.

As Computer Science students are paranoid and think they can doeverything better, we naturally wanted to build a solution our self, where no personal data is shared or made public.
