Doesn't look like it. There doesn't seem to be much of anything about discovering compatible things on other fediverse platforms (e.g. MBIN magazines, a.gup.pe groups, pixelfed groups [if they even exist], PeerTube channels, discourse / hubzilla whatevers, Flipboard thingies, etc).
For PeerTube, a good discovery tool is https://fedi.video, but that also involves tootling around on some other instance and copy/pasting handles back to your own platform, so it's not exactly that convenient.
