I wrote a nano tool that tries to extract the #Fediverse accounts of your #Twitter followings: https://fedifinder.glitch.me/

It searches for the patterns @[email protected], [email protected] and host.tld/@user in the screen name, description, location and URL field. It displays them to you in the correct format for easy copying as well as a CSV download that can be imported to #Mastodon.

New version: https://fedifinder-backup.glitch.me/

Fediverse accounts of your X/Twitter followings

@Luca great tool, thank you 🙏 I recommend advising people to search their *own* instance for each username since this is not an obvious way to follow accounts. The other way of loading each profile URL has terrible follow UX if it’s on a server you’re not signed into.
@kumarvibe That's why it shows the full handle instead of links. But the easiest way is to import the CSV. Maybe edit it before, to remove some accounts.
@Luca yeah, I just meant add instructions for how to follow the accounts. For example, I didn’t even know one could import a csv file!
