That's cool - I don't text that much (apparently in the lowest 2%!) but it was fun to see. The word cloud was great, as were the graphs.
Feedback wise:
The graphs didn't use as much y axis as they could - i.e I think I had a max value of like 150 in one graph, but the axis went to 400.
Other than that, the onboarding video references ourchatstory.com rather than .co; which isn't a problem if you're already on the domain I guess!
Good work!
