Twitter has announced plans for a new "super follow" feature which will enable account holders to charge for exclusive additional content.

Axar.az reports that this could take the form of extra tweets, joining a community group or receiving a newsletter, the firm said.

Twitter unveiled its plans at a virtual event held for investors.

It's the first time in a while that the platform has announced significant changes to the way in which people can use it.

It also said it was testing a live audio discussion service - which has proved popular on a new rival, the audio-only social network Clubhouse.

"Why don't we start with why folks don't believe in us," said Twitter founder Jack Dorsey.
