When copying content from websites into ChatGPT, Claude, Gemini, or DeepSeek, raw web pages are loaded with cluttered navigation menus, banner ads, cookie popups, and sidebar links. This bloat squanders your LLM's precious context window, wastes tokens, and triggers the "Lost in the Middle" phenomenon, degrading AI response accuracy. ContextLion is built specifically for AI-augmented workflows. Operating with an uncompromising 100% Local-First architecture, it surgically extracts core article content, eliminates all noise, generates elegant GitHub Flavored Markdown, and estimates CJK & Latin token consumption in real time! ⚡ One-Click AI-Optimized Context • Intelligent Article Extraction: Powered by the industry-standard Mozilla Readability algorithm to capture the article body, title, author, and publication timestamp. • Noise Elimination: Automatically purges banner ads, sticky headers, related articles, sidebars, and tracking widgets. • Image Bloat Protection: Strips heavy Base64 Data URL images automatically, preventing a single embedded image from devouring tens of thousands of tokens. ✨ Built-in AI Prompt Presets • Wrap extracted context into proven, production-grade prompt templates ready to paste into any LLM: - ⚡ Executive Summary (TL;DR) - 🎯 Key Action Items & Strategic Takeaways - 👶 Explain Like I'm 5 (ELIF) - 🌐 Professional Translation (Traditional Chinese / Multi-language) - 💻 Code Architecture & API Schema Extraction • Custom Prompt Builder: Add, edit, and organize your own reusable prompt presets. 🎯 Surgical Element Picker • Need just a specific table, benchmark, or code snippet? Activate the interactive visual picker. Hover over any DOM section and click to capture only that element as pristine Markdown—completely bypassing the rest of the page. 📦 Multi-Tab Context Pack & Batch ZIP Export • Power research made simple: Select multiple open research tabs across various domains. • Aggregated Token Counter: View real-time combined token counts across all selected tabs. • Export Flexibility: Copy as a single unified AI prompt context, or download as a structured ZIP archive (.zip) containing individual Markdown files. 🔒 100% Local-First & Zero Telemetry • No Remote Backend: All DOM sanitization, HTML-to-Markdown transformations, and token math happen entirely within your local browser runtime. • Zero Analytics: No Google Analytics, no Sentry, no Mixpanel, and zero telemetry beacons. • Your reading habits, URLs, and research data never leave your device! 🛡️ PERMISSIONS & PRIVACY PROMISE ContextLion strictly follows the Principle of Least Privilege: • activeTab / scripting: Only reads DOM content when you explicitly click the extension or launch the element picker. • storage / unlimitedStorage: Stores your preferences and local history solely on your computer. • tabs: Only reads window tab titles during multi-tab Context Pack selection.
