Ask HN: Is anyone solving the problem of having to use many different chat apps?

Different parts of my social network are on: SMS, WhatsApp, FB Messenger, Telegram, Signal, Keybase, Slack, IRC, and Google Hangouts.

It's super inconvenient having all of those installed, running, updating and notifying me on my laptop and phone, leaving aside the fact that I have to remember who uses what, when and how.

Are there any efforts to unify the experience somehow, kind of like how for a while I was able to use Pidgin and Trillian to message across multiple platforms? That was over a decade ago.

Anyone who solved this could easily charge me $100+ a year.
