Side A -- For store owners

Make your store visible to every AI agent on the planet.

Right now, when someone asks ChatGPT to find a product, it cannot read your store. 16,000 tokens of HTML noise. No price. No stock. No trust. The agent gives up and recommends your competitor.

GEOstack Shadow is a free WooCommerce plugin that fixes this. Install it, and every product becomes machine-readable instantly.

Side B -- For developers

Make any app controllable by any AI agent.

Define a Prompt File. GEOstack reads it and auto-generates MCP tools. The user connects their AI via Agentic SSO. The agent operates your app natively. You do not build an API. You do not build a UI.

Chat-as-an-OS. The complete replacement of the traditional GUI. One Prompt File is your entire integration. Works with Claude, ChatGPT, Gemini, Grok, and any MCP-compatible agent.

// That's it. Any AI agent in the world can now operate your app.
// No SDK. No API docs. Just this file.
01

Define a Prompt File

A JSON schema that describes your app's data model, tools, and allowed operations. This is your API -- but for AI agents, not developers.

02

User connects their AI

One click to connect via Agentic SSO. GEOstack issues a scoped Visa. The agent gets dynamic MCP tools from your Prompt File.

03

AI operates your app

The user's AI reads and writes their own data through the SDK. You don't build an API. You don't build a UI. GEOstack handles everything.

app.ts -- Your entire GEOstack SDK integration
// npm install geostack-connect
import { GEOstack } from 'geostack-connect';

GEOstack.init({
  promptFile: './geostack.prompt.json',
  db: drizzleClient,
  userResolver: (id) => db.users.findBy({ geostack_id: id })
});

// That's it. Your app is now a Chat-as-an-OS.
// Any user can control it via Claude, ChatGPT, Grok, or Gemini.

The agentic internet is here. Build on it.

Free infrastructure for developers. Free tools for store owners. The new standard starts now.
