Why Scribbler?

AI Without the Infrastructure

Scribbler runs AI models directly in your browser using WebGPU. No servers to manage, no APIs to pay for, no data leaving your device.

100% Private

All AI runs on your device. Your data never leaves the browser — no server, no tracking.

Zero Setup

No backend, no install, no npm, no Python. Open a URL and start running AI instantly.

WebGPU Accelerated

Leverages WebGPU for near-native performance on LLMs, image generation, and ML inference.

Load Any Library

Dynamically import TensorFlow.js, ONNX Runtime, Transformers.js, Plotly, and more from CDNs.

Share & Collaborate

Save notebooks as .jsnb files, share via URL, or push directly to GitHub.

Interactive Notebooks

Mix JavaScript, HTML, CSS, and Markdown in live cells. See AI output as you code.

AI Meets the Browser

WebGPU and JavaScript are unlocking a new era of on-device AI — accessible to everyone, everywhere.

Live Demo

WebNN & ONNX
Right in Your Browser

Run Stable Diffusion, LLM chat, and text-to-speech directly on your device using WebNN and ONNX Runtime Web. No downloads, no cloud, no API keys — your browser's GPU does all the work.

  • Image Generation — Stable Diffusion via WebNN + ONNX Runtime
  • LLM Chat — Converse with language models on-device
  • Text to Speech — Kokoro TTS running entirely client-side

How It Works

Get started in seconds. Load AI models, write code, and see results — all in interactive notebook cells.

Getting Started

  • •No installation needed. Open app.scribbler.live and start immediately.
  • •Or download / clone the GitHub repo to self-host.
  • •No npm, no Python, no Docker. Just a browser with WebGPU support.

Quick Examples

Load an LLM in one line:

await scrib.loadWebLLM("Llama-3.1-8B-q4f16")

Plot a chart from data:

range(0,10,0.01).map(Math.sin).plot()

Show any output inline:

scrib.show("Hello World")

Example Notebooks

Browse 50+ AI and data examples in the Gallery, or explore the examples on GitHub. Each notebook can be opened instantly in the app via URL.

Interactive Cells

  • •Each notebook is made of code and doc cells. Code cells run JavaScript; doc cells render HTML/Markdown.
  • •AI model outputs — generated images, chat responses, charts — render inline below the cell.
  • •Press ▶ or Cmd/Ctrl-Enter to execute. Rearrange, add, or delete cells freely.

Load Any AI Library

Dynamically import libraries like TensorFlow.js, Transformers.js, WebLLM, ONNX Runtime, Plotly, and D3 from CDNs — no bundler needed. Libraries load on demand and stay cached.

Share & Collaborate

Save notebooks as .jsnb files and share via URL — anyone can open them instantly. Push to and pull from GitHub directly. Export notebooks or just the output as HTML.

Self-Host Anywhere

Scribbler is pure static files — host it on any web server, S3 bucket, or GitHub Pages. No backend process, no database, no containers. Perfect for air-gapped or enterprise environments.
