Omniglass

The Execution Gap

Every AI tool on your desktop does the same thing: you show it your screen, and it talks at you. OmniGlass reads your screen, understands the context, and gives you buttons that execute.

How It Works

You snip your screen → native OCR extracts text on-device (Apple Vision on macOS, Windows OCR on Windows — no images leave your machine) → text goes to an LLM (Claude, Gemini, or Qwen-2.5 running locally) → the LLM classifies the content and returns a menu of actions in under 1 second → you click an action → it executes through the built-in handler or a sandboxed MCP plugin.

Two inputs (snip or type), one pipeline, same plugin system.

No OmniGlass servers. Your key talks directly to the provider. We never see your data.

Build a Plugin in 5 Minutes

OmniGlass is a platform built on the Model Context Protocol (MCP). The built-in actions are just the starting point.

Here's what makes plugin development different from anything else you've built: you don't write prompt engineering. OmniGlass handles the Screen → OCR → LLM pipeline. By the time your plugin code runs, you're receiving clean, structured JSON. You write the API call. That's it.

A complete plugin that sends whatever you snip to a Slack channel:

// index.js — that's the whole plugin
import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";

const server = new Server({ name: "slack-post", version: "1.0.0" }, {
  capabilities: { tools: {} }
});

server.setRequestHandler("tools/list", async () => ({
  tools: [{
    name: "post_to_slack",
    description: "Send captured screen content to a Slack channel",
    inputSchema: {
      type: "object",
      properties: {
        message: { type: "string", description: "The content to post" },
        channel: { type: "string", description: "Slack channel name" }
      },
      required: ["message"]
    }
  }]
}));

server.setRequestHandler("tools/call", async (request) => {
  const { message, channel } = request.params.arguments;
  await fetch(process.env.SLACK_WEBHOOK_URL, {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ channel: channel || "#general", text: message })
  });
  return { content: [{ type: "text", text: `Posted to ${channel || "#general"}` }] };
});

const transport = new StdioServerTransport();
await server.connect(transport);

// omni-glass.plugin.json — the manifest
{
  "name": "Slack Post",
  "command": "node",
  "args": ["index.js"],
  "env_keys": ["SLACK_WEBHOOK_URL"],
  "permissions": { "network": ["hooks.slack.com"] }
}

Drop it in ~/.config/omni-glass/plugins/slack-post/. Restart. Your action appears in the menu.

What the community could build (each under 100 lines):

• Snip a bug → create a Jira / Linear / Asana ticket
• Snip a mockup → generate Tailwind CSS
• Snip a SQL error → query your schema, suggest and run the fix
• Snip a receipt → extract the total, log to your expense tracker
• Snip an API response → generate TypeScript types
• Snip a whiteboard sketch → convert to a Mermaid diagram
• Snip a meeting invite → check Google Calendar for conflicts
• Snip anything → save to Obsidian / Notion / Logseq

The best plugin ideas will come from you. Open a discussion or just build it and open a PR.

The Security Moat

Claude Desktop runs MCP plugins with your full user permissions. A rogue plugin — or a prompt injection — has access to your SSH keys, .env files, and browser cookies.

OmniGlass is a Zero-Trust Execution Engine.

Quick Start

No API key? OmniGlass runs Qwen-2.5-3B locally via llama.cpp. Full pipeline in ~6 seconds, entirely offline.

macOS (primary platform — requires macOS 12+, Rust, Node.js 18+):

git clone https://github.com/goshtasb/omniglass.git
cd omniglass
npm install
npm run tauri dev

1. Click the OmniGlass icon in your menu bar
2. Settings → paste your Anthropic or Google API key, or select Local and download the Qwen model
3. Snip Screen → draw a box → see the action menu → click an action

Pre-built .dmg installer coming soon.

Windows — compiles and passes CI. Needs real-hardware testing. If you have a Windows machine, see Issue #1.

Linux — planned. Needs Tesseract OCR, Bubblewrap sandbox, Wayland tray support. This is a meaningful contribution if you want to own it. See Issue #2.

Contributing: The Sandbox Challenge

We challenge you to break the sandbox.

Every plugin runs inside a kernel-level sandbox-exec profile. If you can read ~/.ssh/id_rsa from a plugin process, that is a critical security bug. Open an issue immediately.

Beyond the sandbox:

• 🔌 Build a plugin. Pick any API you use daily, make it an OmniGlass action. The Plugin Developer Guide gets you from zero to working plugin in 5 minutes.
• 🪟 Own the Windows port. It compiles. It needs a champion. (Issue #1)
• 🐧 Own the Linux port. Tesseract + Bubblewrap + Wayland. (Issue #2)
• 💬 Tell us what to build. The Discussions tab drives the roadmap. The features that get the most demand get built first.
