Twitter explores 'undo send' feature

Have you ever sent out a tweet and immediately regretted it?

Well, Twitter is exploring an "undo send" function that would allow tweets to quickly be withdrawn before others are able to see it.

But you'll have to pay for it.

A Twitter spokeswoman on Friday confirmed to Reuters the popular social media platform is testing out a quick recall function but only as it explores ways to launch and differentiate a paid subscription version. The spokeswoman also went on to say that Twitter will be testing out and putting in place other features for a paid version over time.

Testing for the possible new feature was first revealed by an app researcher who discovers unannounced social media features by looking at the sites' codes. She then tweeted an animation showing a tweet with a spelling error where an "undo" button was available before a short timer ran out.

Twitter is looking for ways to make money beyond its reliance on just ad revenues. The idea of a paid subscription model is something Twitter has said it is working on, including a "super follow" feature that would allow users to charge followers for access to exclusive content. That feature is expected to launch later this year.

Other thing, however, that's not likely to change... the inability to actually edit tweets after they are sent out.

Even though users have long clamored for an edit button, CEO Jack Dorsey has stood firm that that will never happen.
