XCheck - Non-Follower Finder

XCheck instantly finds accounts on X (formerly Twitter) that don't follow you back. Open your Following page, scroll, and watch non-followers appear in real time — right inside a clean side panel. No API tokens. No passwords. No data leaves your browser. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Step 1: Open XCheck from your Chrome toolbar. It launches as a side panel alongside X. Step 2: Enter your X username. XCheck opens your Following page in a new tab. Step 3: Scroll down through your Following list. As each profile loads, XCheck checks whether that account follows you back. Step 4: Non-followers appear instantly in the side panel with their display name and handle. That's it. No complicated setup. No account linking. No OAuth screens. You scroll, XCheck scans. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY XCHECK EXISTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ You're following 2,000 people. How many follow you back? You genuinely don't know — and X doesn't make it easy to find out. You could click into profiles one by one and look for that tiny "Follows you" label. For a few dozen accounts, that's tedious. For hundreds or thousands, it's not realistic. XCheck solves this in minutes. It reads your Following page as you scroll through it and identifies every account that doesn't follow you back. No clicking into individual profiles. No guesswork. Just a clear, scrollable list of non-followers — built in real time as you browse. Your follower-to-following ratio matters. X's own algorithm factors in how balanced your following list is. If you're following far more people than follow you, your reach and visibility take a hit. Cleaning up non-followers isn't vanity — it's a practical step toward better engagement and a healthier account. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ REAL-TIME NON-FOLLOWER DETECTION XCheck identifies accounts that don't follow you back as they appear on your Following page. No batch processing, no waiting for a report. Results stream in live, one by one, so you can see non-followers the moment they're detected. SIDE PANEL INTERFACE Everything runs inside Chrome's built-in side panel. Your X tab stays open on the left while XCheck displays results on the right. No popups. No separate windows. No tab switching. You browse and review simultaneously. WHITELIST Not every non-follower deserves an unfollow. Maybe it's a news account, a favorite creator, or a brand you want to keep following regardless. Star any account to move it to your Whitelist. Whitelisted users are excluded from the non-followers list so you can focus on the accounts you actually want to clean up. COPY ALL PROFILE LINKS One click copies the X profile URLs of every detected non-follower (minus your whitelisted accounts) to your clipboard. Paste them into a spreadsheet, share them with a social media manager, or use them however you need. You can also switch to the Whitelist tab and copy just those links. DARK MODE AND LIGHT MODE Full theme support. Toggle between dark and light with a single click. Your preference is saved and persists across sessions. SCAN COUNTER A live counter in the header shows how many accounts have been scanned and how many non-followers have been found. You always know exactly where you are in your Following list. CLEAR AND RESCAN Starting fresh is one click away. Clear your current scan results and scroll through again. Useful after you've unfollowed some accounts and want a clean count. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FREE VS PRO ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ XCheck is free to use. The free tier scans up to 100 accounts per session — more than enough to get a feel for how it works and to identify your first batch of non-followers. Need to scan your full Following list? XCheck Pro unlocks unlimited scanning for a one-time payment of $4.99. No subscription. No recurring charges. Pay once, use forever. Activate Pro instantly by pasting your license key directly in the extension. Scanning resumes right where it left off — no need to start over. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY AND SECURITY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ XCheck is designed with privacy as a foundation, not an afterthought. NO API ACCESS: XCheck does not use the X/Twitter API. It does not connect to X's servers on your behalf. It simply reads the page you're already looking at in your browser. NO PASSWORDS: XCheck never asks for your X password, your login credentials, or any form of authentication. You log into X yourself — XCheck just reads the public DOM of the Following page you're viewing. NO DATA COLLECTION: Your scan results, your Following list, and your non-follower data stay entirely in your browser. Nothing is sent to our servers. Nothing is stored remotely. Nothing is shared with third parties. NO TRACKING: XCheck does not include analytics, telemetry, or any form of usage tracking. We don't know who you are, who you follow, or what your results look like. LOCAL STORAGE ONLY: Your username, theme preference, whitelist, and license status are saved in Chrome's built-in storage. That data syncs across your Chrome browsers if you're signed into Chrome — but it never touches our infrastructure. MINIMAL PERMISSIONS: XCheck requests only the permissions it needs — side panel access, storage for preferences, and tabs to open your Following page. No broad host permissions. No background network requests beyond license activation. This matters because most follower-analysis tools require you to hand over your X credentials or authorize an app via OAuth. That gives the tool access to your entire account — your DMs, your posts, your private data. XCheck avoids this entirely. It works by reading what's already on your screen, nothing more. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IS XCHECK FOR? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CREATORS AND INFLUENCERS If you're building an audience on X, your follower-to-following ratio is a signal of credibility.
