With this script, you can remove all retweets you are retweeted on Twitter.

twitter-remove-retweets.js

const timer = ms => new Promise(res => setTimeout(res, ms));

// Unretweet normally
const unretweetTweet = async (tweet) => {
      await tweet.querySelector('[data-testid="unretweet"]').click();
      await timer(250);
      await document.querySelector('[data-testid="unretweetConfirm"]').click();
      console.log('****// Unretweeted Successfully //****')
}

// Sometimes twitter shows your retweet but green retweet button is invisible and therefore you need to retweet again for make unreweet. This function is for that.
const unretweetUnretweetedTweet = async (tweet) => {
      await tweet.querySelector('[data-testid="retweet"]').click();
      await timer(250);
      await document.querySelector('[data-testid="retweetConfirm"]').click();
      console.log('****// Retweeted Successfully //****')
      await timer(250);
      unretweetTweet(tweet);
}

setInterval(async () =>
{
      // Get all tweets
      const retweetedTweetList = document.querySelectorAll('[data-testid="socialContext"]');
      console.log('****// Retweeted Tweet List Collected //****')
      for (const retweet of retweetedTweetList) {
            const tweetWrapper = retweet.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement;
            tweetWrapper.scrollIntoView();
            
            const isRetweeted = tweetWrapper.querySelector('[data-testid="unretweet"]');
            if (isRetweeted) {
                  console.log('****// Green Retweet Button Found - Starting "unretweetTweet" process //****')
                  await unretweetTweet(tweetWrapper);
            } else {
                  console.log('****// Green Retweet Button Not Found - Starting "unretweetUnretweetedTweet" process //****')
                  await unretweetUnretweetedTweet(tweetWrapper);
            }
            await timer(2000);
      }
      console.log('****// List Completed //****')
      console.log('****// Scrolling //****')
      console.log('                  ')
      console.log('                  ')
      console.log('                  ')
      console.log('                  ')
      console.log('                  ')
      console.log('                  ')
      console.log('                  ')
      console.log('                  ')
      await window.scrollTo(0, document.body.scrollHeight);
}, 60000);

as of 2025 this script does not work.

I have updated it to use button instead of div for unretweet test id as following and confirmed it works:

const timer = ms => new Promise(res => setTimeout(res, ms));

const unretweetTweet = async (tweet) => {
try {
await tweet.querySelector('button[data-testid="unretweet"]').click();
await timer(250);
await document.querySelector('div[data-testid="unretweetConfirm"]').click();
console.log('// Unretweeted Successfully //');
} catch (error) {
console.error('Error during unretweet:', error);
}
};

const unretweetUnretweetedTweet = async (tweet) => {
try {
await tweet.querySelector('div[data-testid="retweet"]').click();
await timer(250);
await document.querySelector('div[data-testid="retweetConfirm"]').click();
console.log('// Retweeted Successfully //');
await timer(250);
unretweetTweet(tweet);
} catch (error) {
console.error('Error during unretweetUnretweetedTweet:', error);
}
};

const processTweets = async () => {
const retweetedTweetList = document.querySelectorAll('span[data-testid="socialContext"]');
console.log('// Retweeted Tweet List Collected //');

for (const retweet of retweetedTweetList) {
const tweetWrapper = retweet.closest('[data-testid="tweet"]');
tweetWrapper.scrollIntoView();

const isRetweeted = tweetWrapper.querySelector('button[data-testid="unretweet"]');
if (isRetweeted) {
  console.log('****// Green Retweet Button Found - Starting "unretweetTweet" process //****');
  await unretweetTweet(tweetWrapper);
} else {
  console.log('****// Green Retweet Button Not Found - Starting "unretweetUnretweetedTweet" process //****');
  await unretweetUnretweetedTweet(tweetWrapper);
}
await timer(2000);

}
console.log('// List Completed //');
console.log('// Scrolling //');
console.log(' ');
console.log(' ');
console.log(' ');
console.log(' ');
console.log(' ');
console.log(' ');
console.log(' ');
console.log(' ');
window.scrollTo(0, document.body.scrollHeight);

// Call processTweets again using requestAnimationFrame to keep the loop going
requestAnimationFrame(processTweets);
};

// Start the process initially
processTweets();
