Convinced my organisation to use Mastodon and Bsky. Any userfull tools to automate crossposting?

I know that there should be tools to make it easier to publish content to Twitter/Bluesky/Mastodon, without doing the work thrice. Do you know a good one? Can you share your experience with using them? Thanks! I hope the new platforms are not gonna get ditched immediately...

Edit: Wow I didn't expect that the solutions were often expensive and complex tools (with way too much "AI").
