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();

Here's work like 300 unretweet a day before your account can't load your profile anymore:

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

let totalUnretweeted = 0;
let isRunning = true;

// Stop the script by running: isRunning = false; in console
window.stopUnretweet = () => {
  isRunning = false;
  console.log("// Stopping script... //");
};

const unretweetBatch = async () => {
  const retweetedTweetList = document.querySelectorAll(
    'span[data-testid="socialContext"]',
  );

  if (retweetedTweetList.length === 0) {
    console.log("// No retweets found, scrolling... //");
    return 0;
  }

  let batchCount = 0;

  for (const retweet of retweetedTweetList) {
    if (!isRunning) break;

    const tweetWrapper = retweet.closest('[data-testid="tweet"]');
    if (!tweetWrapper) continue;

    tweetWrapper.scrollIntoView({ behavior: "smooth", block: "center" });
    await timer(800);

    const unretweetButton = tweetWrapper.querySelector(
      'button[data-testid="unretweet"]',
    );

    if (unretweetButton) {
      try {
        unretweetButton.click();
        await timer(500);
        const confirmButton = document.querySelector(
          'div[data-testid="unretweetConfirm"]',
        );
        if (confirmButton) {
          confirmButton.click();
          batchCount++;
          totalUnretweeted++;
          console.log(`✓ Unretweeted #${totalUnretweeted}`);
        }
      } catch (error) {
        console.error("Error:", error);
      }
    }

    await timer(3000); // 3 second delay between unretweets
  }

  return batchCount;
};

const autoUnretweet = async () => {
  console.log("🚀 Starting autonomous unretweet script...");
  console.log("⚠️ To stop at any time, type: stopUnretweet()");
  console.log(" ");

  while (isRunning) {
    const processed = await unretweetBatch();

    if (!isRunning) break;

    // Scroll down to load more
    console.log("📜 Scrolling to load more tweets...");
    window.scrollTo(0, document.body.scrollHeight);

    // Wait for new tweets to load
    await timer(4000);

    // If no tweets were processed, wait longer before trying again
    if (processed === 0) {
      console.log(
        "⏸️  No retweets found. Waiting 10 seconds before checking again...",
      );
      await timer(10000);
    }
  }

  console.log(" ");
  console.log("✅ Script stopped. Total unretweeted: ${totalUnretweeted}");
};

autoUnretweet();
