BytNode-AI in five minutes

Financial AI agents that run on your own machine, on the subscription or the API key you already have, with BytNode market data and your exchange accounts at hand.

What it is

BytNode-AI is an agentic AI application, specialised in finance and crypto markets. It runs on your computer, opens in your browser, and hosts as many agents as you want. Each agent has a profession (generalist, analyst, strategist or quant), tools (your files, a shell, the web, sub-agents), the market through BytNode, and, if you allow it, your exchange accounts.

The model underneath is yours: your Claude, OpenAI, Gemini, GitHub Copilot, Grok or Mistral subscription, or any model on OpenRouter with a key. There is no BytNode-AI server in between.

What you need

Node.js 20.9 or newer, on Windows, macOS or Linux.
A way to reach a model: one of the six subscriptions, or an OpenRouter key.
A BytNode key for market data, from your BytNode console. Without it the agents still run, but they have no market data.

Quick start

Run
```
npx bytnode-ai
```
It starts on http://localhost:3777 and opens your browser. The setup assistant appears on first launch.
Sign in with what you already pay for
In Authentification, pick your subscription and press Se connecter: the vendor’s page opens, you sign in, and the state updates by itself. Or paste an OpenRouter key. Add your BytNode key below.
Create an agent
A name, a profession, an LLM provider, and a context. Then ask it something: it answers with the market at hand.

Everything stays on your machine. Keys and conversations live in your browser’s storage; workspaces, skills and installed agents in ~/.bytnode-ai. What leaves is what you send to your model, and your own calls to BytNode and to your exchanges.
