The whole tool, tab by tab

It works. You watch.

The agent runs real apps on its own desktop. Here it fills a customer form field by field. You see every move as a live stream with a virtual cursor, and take over the moment you want to.

Simulated session for illustration

Supervise up to 8 desktops from one screen.

Each agent gets its own hidden desktop in your session. One view, all runs, step in anywhere. Your own mouse and windows stay untouched.

Agent desktops

Run several agents side by side, each one on its own invisible Windows desktop, none of them on yours.

Open desktops

Up to eight at a time, each one a real Windows desktop of its own.

Simulated session for illustration

Teach it once. It replays without a model.

Show the agent a task by doing it yourself. It stores your intent, not your pixels, and replays it with zero model calls.

As of August 2026, OpenAI ships record-and-replay on macOS only and excludes the EEA, the UK and Switzerland. agentfenster records and replays on Windows and runs locally in Europe.

Recordings

Every run is kept as a replayable film. Scrub it, step through it, change the speed.

Every action is checked for effect

Each click is checked against the window's element tree. No change means an error: reported, never dressed up as success.

What it actually is

  • A second Win32 desktop inside your Windows session, created with the standard CreateDesktop API.
  • The agent reads the UIA element tree, not screenshots.
  • Live stream with a virtual cursor; take over anytime. It never takes your mouse.
  • Every run is stored as a replay with a timeline.
  • Real ConPTY terminal plus MCP server for Claude Code.
  • Credentials stay in the Windows Credential Manager: the model sees placeholders.
  • 2FA codes are read from your Gmail or Outlook inbox, locally.
  • Runs locally. No telemetry. No account.

What it can see, and what it can't

  • The model sees element trees and placeholders, never your stored credentials.
  • Network traffic consists of the model calls you configure; there is no telemetry endpoint.
  • Verify it yourself with any packet capture.
