The CoTweets feature allows two accounts to tweet together and tag each other in a single tweet.

Twitter said in a post that the new feature is currently available for a limited time to a limited number of users in the US, Canada, and Korea after testing the idea in the earlier part of 2022.

Reportedly, the CoTweets feature, which enables the primary tweet author to ask for a second person to be tagged in the tweet and debate its subjects through Direct Message, has been tested by several Twitter users today.

The co-authored tweet needs the second account’s permission; while it was written by two persons, comments only appear to be aimed at the original author in the final form of the tweet, ANI
reported.

If one accepts a CoTweet invitation but then decides not to want to co-author that CoTweet, Twitter will say that they can remove a CoTweet after it’s published. The first tweeter then retweets the CoTweet as usual.

Also, since only two authors can appear in the header of a CoTweet at a time, users can only invite one co-author per CoTweet. As a small test, some accounts in Canada, Korea, and the US can now invite others with a different accounts to CoTweet.
