Hey, in the last couple of weeks we built a Chrome app that unifies a lot messenger platforms. It's a fun side project which is slowly gaining traction on the Chrome Web Store (2k users, organically grown). We have received a lot of positive feedback already, especially from Chrome OS users, but wanted to show it to a wider audience now.
As usual, if you have any questions about it feel free to ask us anything - we are happy about any feedback!
