Local AI Sidebar

Privacy-first AI sidebar using Chrome's built-in AI. Process content locally with no data sharing.

**What Local AI Sidebar Does** Local AI Sidebar brings powerful AI capabilities directly to your browser using Chrome's built-in Gemini Nano model. All processing happens locally on your device - your content never leaves your computer. **Key Features:** • **Privacy-First Chat**: You copy/paste content to analyze - AI never automatically accesses pages • **Custom Prompts**: Create and save your own prompts for specific tasks • **Knowledge Management**: Upload PDFs and add text documents that AI can reference when answering questions • **Conversation History**: Maintain chat history across tabs with "New Chat" option • **Complete Offline**: Works without internet after initial model download • **Local Storage**: All data stored in Chrome's local storage - never synced to cloud **Why Install It** Most AI tools send your content to external servers, raising privacy concerns. Local AI Sidebar is different: Traditional AI Tools: • Require subscriptions and API keys • Send data to external servers • Need internet connection • Cost money monthly Local AI Sidebar: • Completely free - no subscriptions • Zero data transmission - everything stays local • Works offline after setup • You control what content AI sees **How It Works** Simple 3-step setup: 1. Install extension (no registration required) 2. Click extension icon to open sidebar 3. AI model downloads automatically (~2GB one-time download) The extension uses Chrome's built-in Prompt API to access Gemini Nano locally. When you paste content or upload PDFs, everything processes on your device without any network calls. **Knowledge Management (RAG)** Go beyond simple chat - build your own knowledge base: • **Upload PDFs**: Add documents for AI to reference • **Import Text**: Save articles, notes, or any text content • **Smart Search**: AI automatically finds relevant information from your knowledge base when answering • **Private Storage**: All documents stored locally in your browser - never uploaded Perfect for researchers, students, and professionals who want to chat with their documents privately. **Important Notes** Local AI models are experimental technology: • Performance varies based on hardware capabilities • Requires computational resources • Responses may be slower than cloud-based AI • Not suitable for critical decision-making without verification **Privacy Guarantee** • AI never automatically accesses webpage content • You explicitly choose what to share by copying/pasting • All data stored in Chrome local storage only • Nothing synced to Google accounts or cloud • Open source - full code available on GitHub for review For maximum privacy, use a separate Chrome profile for AI-assisted browsing. **Transform Your Browsing Experience** Stop compromising between AI assistance and privacy. Get powerful AI with complete privacy protection - no accounts, no subscriptions, no data sharing. **Open Source & Transparent** This extension is open source under MIT license.
