  X Focus Filter — Take Back Your X/Twitter Timeline
  
  Tired of scrolling through spam, NSFW content, crypto scams, and engagement bait on X (formerly Twitter)? X Focus Filter is a lightweight Chrome extension that filters your timeline in real-time, showing only the professional and technical content you actually care about.
  
  No API keys. No data collection. No servers. Everything runs 100% locally in your browser.
  
  
  THE PROBLEM
  
  X's algorithmic timeline doesn't respect your time. Your feed is cluttered with:
  
  - Spam accounts and NSFW/adult content mixed into your professional feed
  - Crypto scam promotions, fake giveaways, and airdrop spam
  - Engagement bait, rage-inducing culture war posts, and celebrity gossip
  - Content completely unrelated to your work and interests
  
  You open X to stay updated on tech and AI news, but end up wasting 30 minutes scrolling through noise. X Focus Filter fixes this by letting you define exactly what topics you want to see.
  
  
  HOW IT WORKS
  
  X Focus Filter scans each tweet as it loads on your timeline and matches it against carefully curated keyword dictionaries. Tweets that don't match your selected topics are instantly and smoothly hidden. No page reloads, no delays — filtering happens in real-time as you scroll.
  
  1. A tweet appears in your timeline
  2. The extension extracts the tweet text, author name, and any link preview content
  3. It checks against the spam/NSFW blacklist (always active)
  4. It matches against your selected topic keywords
  5. The tweet is shown or hidden instantly
  
  The entire process takes milliseconds per tweet and has zero impact on your browsing performance.
  
  
  8 TOPIC CATEGORIES
  
  Choose the topics that matter to you. Each category contains 50-100+ carefully curated keywords in both English and Chinese:
  
  Tech — Software engineering, hardware, cloud computing, programming languages (JavaScript, Python, Rust, Go), frameworks (React, Vue, Next.js), DevOps, databases, cybersecurity, major tech companies (Apple, Google, Microsoft, NVIDIA)
  
  AI / Machine Learning — Large language models (GPT, Claude, Gemini, LLaMA, DeepSeek), deep learning, neural networks, computer vision, NLP, AI agents, prompt engineering, image generation (Stable Diffusion, Midjourney, DALL-E), AI coding tools (Copilot, Claude Code)
  
  Business — Startups, venture capital, funding rounds, IPOs, acquisitions, revenue, fintech, market analysis, hiring trends, Y Combinator
  
  Open Source — GitHub, GitLab, open source licenses, pull requests, npm, PyPI, package releases, Linux, community projects
  
  Design — UI/UX, Figma, design systems, typography, accessibility (a11y), Tailwind CSS, motion design, prototyping
  
  Crypto / Web3 — Blockchain, Ethereum, Bitcoin, Solana, DeFi, smart contracts, DAOs, Layer 2 solutions, zero-knowledge proofs
  
  Indie Dev — Indie hackers, side projects, bootstrapping, MRR, Product Hunt, build in public, micro SaaS, no-code/low-code tools
  
  Career — Job postings, hiring, remote work, salary, coding interviews, tech leadership, freelancing, career development
  
  
  3 FILTER MODES
  
  Fine-tune how aggressive the filtering should be:
  
  Strict Mode — Requires at least 2 keyword matches per tweet. Best for laser-focused feeds with minimal noise. Great if you only want deeply technical content.
  
  Normal Mode — A single keyword match is enough to show a tweet. The balanced default that works well for most users.
  
  Relaxed Mode — Includes additional broader related terms (like "product", "platform", "tool" for Tech). Shows more content with a wider net. Good if you don't want to miss anything tangentially related.
  
  
  KEY FEATURES
  
  Real-Time Filtering
  Tweets are filtered as they load using a MutationObserver. No page refresh needed. Works seamlessly as you scroll through your timeline.
  
  Spam & NSFW Blocking
  A built-in blacklist automatically hides spam, NSFW content, scam promotions, fake giveaways, and engagement bait. This blacklist is always active regardless of your topic settings.
  
  Custom Keywords
  Add your own comma-separated keywords to the whitelist (always show) or blacklist (always hide). Perfect for niche topics or specific terms you want to filter.
  
  User Whitelist
  Ensure your favorite accounts are never filtered. Add usernames to the whitelist and their tweets will always appear, regardless of content.
  
  Peek Mode
  Temporarily reveal all filtered tweets at reduced opacity. This lets you check for false positives and fine-tune your settings without permanently changing anything.
  
  Floating Status Badge
  A small, unobtrusive badge on the page shows real-time filtering stats (tweets shown vs. hidden) with a quick on/off toggle.
  
  Bilingual Interface
  Full English and Chinese (Simplified) UI support. Switch languages with one click. Keyword dictionaries include both English and Chinese terms for comprehensive coverage.
  
  Real-Time Statistics
  The popup shows live counts of tweets scanned, shown, and hidden so you can see exactly how the filter is performing.
  
  
  PRIVACY FIRST
