KeepXClean - High-Signal Filter for X

Keep X (Twitter) clean: filter reply spam, impersonators, bots, engagement bait, ads, and crowd-blocked accounts.

KeepXClean keeps your X (formerly Twitter) timeline, search results, and reply threads calm, readable, and high-signal. Instead of scraping pages with extra API calls, KeepXClean evaluates X’s own timeline and reply responses locally in your browser — letting you strip noise cleanly or collapse filtered posts into a single-line reason bar with one-click expand, allowlist, or block actions. KEY CAPABILITIES • 9 Deterministic Filter Dimensions & 3 Presets (Light / Balanced / Strict) 1. Reply Spam & Impersonators — Catch ultra-short reply spam, Verified boost bots, low-follower bio-link funnels, and lookalike author impersonators. 2. Engagement Bait & Giveaways — Mute "comment X to get DM" funnels, giveaway loops, and follow-for-follow pods. 3. High-Frequency Posting — Filter accounts exceeding your daily average or rolling 1-hour burst thresholds. 4. Community Blocklist — Optionally filter accounts flagged by aggregated public community reports. 5. Custom Keywords & Regular Expressions — Match across post text, bio, display name, or URLs, with optional reply-only scope and follower exemptions. 6. Public Keyword Packs — 24 curated rules across Clichés & Slop, Crypto & Shilling, Follow Pods, Phishing & Funnels, and NSFW & Illicit. Toggle any rule individually or click "Customize" to edit your own copy. 7. Post Language Filter — Block specific languages or allow only your preferred reading languages. 8. Hashtag & Cashtag Stuffing — Filter posts overloaded with #hashtags or $cashtags. 9. Account Quality & Promoted Ads — Catch brand-new default-avatar spam accounts and hide promoted timeline/reply ads. • Two Clean Display Modes - Hide Cleanly: Strip matched items from timeline/reply responses without leaving empty placeholders. - Collapse Bar: Replace matched posts with a subtle one-line reason bar so you can expand, allowlist, or block on demand. • Safe Quick-Block with 4.5-Second Undo Window - Saves locally first and gives you 4.5 seconds to undo or pick a reason tag before optionally syncing native X block or anonymous community reporting. - Undoing restores only the current action and never accidentally unblocks previously blocked X accounts. • Transparent Activity Log & Portable JSON Backups - Review the 200 most recent filter hits with exact rule evidence. - Import your existing X blocklist by numeric UID with conflict detection against your allowlist. - Export and import validated JSON configuration backups anytime. • 10 Interface Languages - English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish, Portuguese, French, German, and Russian. LOCAL-FIRST PRIVACY • Zero account registration, zero third-party analytics SDKs, and zero remote code execution. • Filtering runs locally in your browser. Optional native X blocking and optional hashed community reporting are controlled explicitly by your preferences. • Website: https://keepxclean.com • Privacy Policy: https://keepxclean.com/privacy/
