ByteBrain is a fully private, in-browser AI Study Companion. It runs powerful LLMs (Large Language Models) directly on your local device's GPU using WebLLM, meaning zero server costs, zero API keys, and 100% privacy.
- 100% Private & Local: Runs completely in your browser. Your notes, questions, and data never leave your device.
- Smart Document Parsing: Upload PDFs and Images. ByteBrain uses
pdfjs-distandtesseract.jsto extract text instantly. - Hardware Accelerated: Powered by WebGPU and
@mlc-ai/web-llmto deliver blazing-fast AI responses using your local graphics card. - Beautiful UI: A premium, dark-mode, glassmorphic interface built with React and custom CSS.
- Non-blocking Worker: Heavy AI processing is offloaded to a WebWorker so the UI remains perfectly smooth while the AI thinks.
- Frontend: React, TypeScript, Vite
- AI Engine: WebLLM (Phi-3-mini-4k-instruct)
- Document Processing: PDF.js (PDFs), Tesseract.js (Images/OCR)
- Icons: Lucide React
- Clone the repository:
git clone https://github.com/kamalesh4044/ByteBrain.git
- Navigate into the directory and install dependencies:
cd ByteBrain npm install - Start the development server:
npm run dev
- Open your browser and navigate to
http://localhost:5173. (Note: The first time you ask a question, ByteBrain will download the AI model to your browser's local cache. Subsequent visits will load instantly!)
ByteBrain can be hosted entirely for free on platforms like Vercel or Netlify. Since all AI processing happens on the client's device, backend hosting is strictly static!
Built with ❤️ for better studying.
