Twitter has confirmed that it is exploring a paid subscription model for some features, and app researcher, Jane Manchun Wong tweeted on Saturday that she has discovered how much it will cost and what it will be called.

“Twitter Blue,” Wong says, will cost $2.99 per month, and will include an Undo Tweets feature and bookmark collections.

Wong says it appears Twitter is working on a tiered subscription model, which she says could mean a less-cluttered, premium experience for the highest-paying subscribers.

However, a Twitter spokesperson declined to comment on Saturday, but the company does not usually confirm or otherwise comment on Wong’s typically accurate discoveries of new features before they launch.

Earlier this month, Twitter acquired Scroll, the $5-per-month subscription service that removes ads from websites that participate.

With the Scroll announcement, Twitter also said it would be winding down Nuzzel, a Scroll service that sent users daily email roundups of top stories in their Twitter feeds.
