Arkhon AI

Arkhon AI — Private AI Assistant for Every Page Chat with any webpage, summarize YouTube videos, and auto-fill forms — powered by AI that runs entirely on your device. No servers, no accounts, no data ever leaving your browser. 🔒 100% Private. Zero Servers. Arkhon runs a local AI model (Gemma 3) directly in your browser. It downloads once, lives on your device, and generates every response locally. No accounts, no API keys, no tracking, and nothing sent anywhere — ever. ✨ What You Can Do 💬 Chat with any page Ask questions about articles, documentation, or research papers and get answers grounded in exactly what's on the page — no tab-switching, no copy-pasting. 📺 Summarize YouTube videos Get a full summary of any video in seconds, straight from its captions — no third-party tools, no uploading your watch history anywhere. 📝 Auto-fill forms with AI Describe yourself once. Arkhon reads any form — job applications, sign-ups, contact forms — and fills it in intelligently. No fixed fields to configure. 🤖 Agent mode Let Arkhon click, type, and complete simple multi-step tasks on a page for you. ⚡ One-click page summaries Instantly condense any article or document down to the essentials. ⚙️ How It Works On first install, Arkhon downloads a compact local AI model (~700MB) and stores it in your browser. After that it works fully offline — no internet connection required, and no data ever leaves your device. The model stays warm in the background, so responses are fast once you're set up. 🆚 Why Local AI? Most AI browser extensions quietly send your browsing activity to an external server — OpenAI, Anthropic, or the extension maker's own backend. Arkhon has no backend to send it to. The AI is entirely yours. ✅ No subscription ✅ No API key ✅ No account ✅ Works offline after setup 🔑 Permissions, Explained • Read page content — so it can answer your questions about the page you're on • Access to all sites — so it works everywhere you browse • Storage — to keep the AI model and your settings on-device • Side panel — to show the chat interface beside the page instead of covering it 💡 Tips • First load takes 1–2 minutes while the model downloads • Works best on pages with substantial text content • YouTube summaries require captions to be enabled on the video • Try Agent mode for multi-step tasks like filling out job applications Private AI.
