X Engagement List — top commenters & who to reply

See who comments on your X posts most, what you haven't replied to, and who doesn't follow back. Local-only.

X Engagement List turns what you already see on X into useful lists. Free to use, with no sign-up, no extra login, and no automated actions. Your data stays in your browser. Features • Top commenters (last 7 / 30 / 90 days): see who replies to your posts most often, with a link to their latest reply. • Replies waiting for you: comments on your posts from the last 30 days that you haven't replied to. • Not following you back: open your own Following page and click “Start snapshot.” The extension scrolls slowly (about one screen every 2 seconds; you can stop anytime) and lists accounts that aren't following you back. • Unfollowers: compare two complete Followers snapshots to see who unfollowed you. • Export any list to CSV. Use multiple X accounts in the same browser. How it works The extension only reads x.com pages you open in your own browser: your posts, replies, notifications, and your own following/followers lists. It saves data locally in your browser using IndexedDB. Nothing is uploaded, and the extension makes no network requests. It does not use the X API or browse on your behalf. The only scripted action is snapshot scrolling, which you start yourself on your own list pages and can stop at any time. What it never does No following, unfollowing, liking, replying, or direct messaging. It does not read passwords, cookies, or X API keys. No analytics, tracking, or ads. Delete an account's data in Settings, or uninstall the extension to delete all data. Privacy policy: https://xeng.aiseenlab.com/privacy Publisher: AI Seen Lab.
