There are online tools for finding out Mastodon addresses of people you follow on Twitter.

I'm not on Twitter so cannot test. However, if you want to try:

🔍 Fedifinder

➡️ Movetodon

Could you let the rest of us know your experiences in the replies?

If you want other people to find you, put your full Mastodon address in your Twitter profile. More info here: https://fedi.tips/how-to-use-mastodon-and-the-fediverse-basic-tips/#WhatsMyAccountsAddress

Debirdify

This is a web app that helps you find out which of the people you follow on Twitter are on Mastodon/in the Fediverse already and follow all of them easily.

@feditips Both worked well for me. Each offers slightly different tools in addition to the basic scan follows / scan followers.

Fedfinder lets you scan any lists you have (private lists in my case), so if you have lists of people you don't follow but read you can search to see if any of them are on the Fediverse.

Debirdify lets you scan blocked and muted lists, convenient if you want to preemptively pull those over as well. It also handles private lists, but clunkier imo.
