Twitter will now prompt users to review and revise "potentially harmful or offensive" replies.
The social media platform, which has often faced criticism over abusive user behaviour, tested the feature last year.
Twitter said the tests showed that the prompts reduced offensive replies.
On Wednesday, the company said it would roll the prompts out to English language accounts using Twitter on Apple and Android.
In
a blog post, Twitter said they had found that prompts led 34% of people
to revise their initial reply or to decide against sending their reply
at all.
Users composed, on average, 11% fewer offensive replies after being prompted for the first time, Twitter said.
They were also less likely to receive offensive and harmful replies back.
It seems, however, that you can still swear at your friends.
Twitter
said the prompts are designed to consider the nature of the
relationship between the accounts that tweets and the account that
replies.
"If
two accounts follow and reply to each other often, there's a higher
likelihood that they have a better understanding of preferred tone of
communication," the blog post said.
Platforms target user behaviour
Tech platforms have grappled in recent years with how to police offensive content, abuse and harassment on their platforms.
Twitter's
most recent statistics, for January to June last year, show that the
platform removed potentially offensive content posted by 1.9 million
accounts, and suspended 925,700 accounts for violating Twitter rules.
The
debate over content moderation has recently become more intense,
because of decisions taken by social media giants against public
officials, particularly former US President Donald Trump.
Mr Trump was banned from a number of platforms, including Twitter and Facebook, following the Capitol Hill riots on 6 January.
Facebook's oversight board upheld the decision on Wednesday,
but criticised the platform for an making the suspension indefinite and
gave it six months to determine a proportionate response.
Although
many believe platforms should be more aggressive in policing online
abuse and false information, many see Mr Trump's ban as an act of
political censorship.
