There's a company called Beeper that hosts a server with a bunch of bridges pre-configured.

Yes there are. I haven't used them in years tho.

That's the reason I use matrix, I have bridges so that if someone messages me on ANY platform, it goes to matrix and I can respond there.

It's not the best solution, but it's worked well for me and I like having everything in one app

Tachiyomi?

Not yet, I made a couple for discussions about whiskey and steam remote play (playing steam games on your phone and stuff). I just realized I should post the massive guide I wrote for the latter in the new community!
