Automate repetitive tasks with natural language instructions.</p> <p>📊 <strong>Data Extraction</strong> — Extract structured data from any page — tables, lists, links, forms.</p> <p>🔌 <strong>Multi-Provider LLM</strong> — Works with llama.cpp, Ollama, OpenAI, Claude, OpenRouter, StudioLM, vLLM. Use your preferred model — or run completely offline.</p> <p>🛡️ <strong>Privacy First</strong> — Run with a local LLM for zero data leakage. No telemetry, no tracking, no accounts required.</p> <p><strong>Why WebBrain?</strong></p> <p>Unlike Claude in Chrome (proprietary, $20/mo, cloud-only), WebBrain is:</p> <ul> <li> <strong>Free forever</strong> and open-source (MIT)</li> <li> <strong>Self-hostable</strong> — bring your own API keys or run locally</li> <li> <strong>Works on Chrome AND Firefox</strong> (Claude only works on Chrome)</li> <li> <strong>Fully offline capable</strong> with local models</li> </ul> <p>Watch this comparison with Claude in Chrome: <a href="https://www.youtube.com/watch?v=iPTjqDP5ApY" rel="noopener noreferrer">https://www.youtube.com/watch?v=iPTjqDP5ApY</a></p> <p>Available on <a href="https://chromewebstore.google.com/detail/webbrain" rel="noopener noreferrer">Chrome Web Store</a> and <a href="https://addons.mozilla.org/firefox/addon/webbrain/" rel="noopener noreferrer">Firefox Add-ons</a>.
