Twitter recently introduced a new monetization feature called “Super Follow,” a new tool from Twitter that lets people earn monthly revenue by sharing subscriber-only content with their followers on Twitter.

“With Super Follow, people can create an extra level of conversation on Twitter (sharing bonus Tweets and more!) to interact authentically with their most engaged followers – all while earning money.”

Twitter says, creating Super Follow content is for anyone who brings their unique perspective and personality to Twitter to drive public conversation, including activities, journalists, musicians, writers, gamers, comedians, and many more. Every day their Tweets, Spaces, Direct Messages, photos, and videos resonate with their audience and create vibrant conversations on Twitter.

To earn through Supper Follow on Twitter, people need to set up a monthly subscription of $2.99, $4.99, or $9.99 a month to monetize their content. In exchange, followers get special access to their unfiltered thoughts, early previews, and subscriber-only conversations from their favorite accounts.

Creators can find and interact with their Super Followers by looking for the Super Followers badge. These public badges will be highlighted under their Super Followers’ name whenever they reply to a creator’s Tweet.

Twitter currently testing this Super Follow feature with a small number of groups in the United States. Twitter also said that interested people can continue to apply to join the waitlist to set up Super Follow by swiping open the sidebar on their Home timeline, tapping on Monetization, then selecting Super Follow.

Twitter also said that people who are interested join the waitlist in the US must have at least 10K or more followers, be at least 18 years old, and must tweet 25 times within the last 30 days, or can read the official Super Follows policy from here.

To subscribe, tap the Super Follow button on an account’s profile to see a description of their paid offerings and pricing. If you’re interested, you can tap again to subscribe via in-app payment.

When you Super Follow someone, you’ll see subscriber-only content in your Timeline and you can unsubscribe at any time in your App Store subscription settings for iOS.

Twitter says, currently, people in the U.S. and Canada using iOS can Super Follow select accounts and will be rolling it out to people using iOS globally in the next few weeks. Creators can share Super Follow Tweets on iOS only and Super Follow Tweets can be viewed on iOS, with Android and twitter.com coming soon.
