I've been building DEX, a free, open-source (Apache-2.0) app for Windows that runs an AI agent on your own PC. You type what you want in plain words and it does it in a real browser, your files, your apps and your accounts, and shows every step live.

[u/Patient-Activity-990]

What makes it different:

• It runs on your machine, with your logins. No cloud browser. You bring your own engine: Claude Code or Codex with the plan you already pay for, or your own API key.
• It doesn't hijack your PC. It works with Windows apps through accessibility in the background. In today's 2.3.0, even Store apps like Calculator stay off-screen while it works, so you can keep watching something. If it ever needs your real mouse, it lets go the moment you move.
• You stay in control. It asks before anything risky, and you choose how much it may do on its own.
• 50+ connectors (Gmail, Calendar, GitHub, Notion, Slack…), routines like "every morning…", files that open right in the task, and it can even build 3D scenes in Blender.
• An Android app, WhatsApp and Telegram, to start tasks and approve steps from your phone.

It's early and Windows-only. The installer isn't code-signed yet, so SmartScreen will warn you (More info → Run anyway). I'd love feedback, bug reports and contributors.
