Attach an app
Attach an app lets you choose one window from an application that is already open and add it to the current message. EvoX does not send a stale image from selection time; it captures the chosen window again when you actually send.
Use the open project brief to list the three decisions needed today.
Pick a window
Let the model see one of your open windows
Attach a window
- Enter
@in the Chat or Cowork composer. - Choose App.
- Select one open window.
- Check the application name and window preview on the attachment card.
- Choose the required tier, then send the message.
The preview helps confirm the selection. If the window closes, becomes protected, or cannot be captured before send, EvoX asks you to choose again instead of silently using an old frame.
Choose View, Read, or Operate
| Tier | Context EvoX receives | When to use it |
|---|---|---|
| View | The selected window's current image at send time. | Inspect layouts, charts, designs, errors, or visual state. |
| Read | The image plus text the application exposes through the operating system's accessibility interface. | Extract interface text, table content, or control labels without relying only on pixels. |
| Operate | In addition to viewing and reading, clicks and typing are allowed only inside the selected window. Actions outside it are refused. | The current connection explicitly supports window operation and the task genuinely needs interaction. |
Operate is not shown on every connection. It is gated by the active connection and the computer-use entry point. When the requirements are not met, EvoX omits the tier instead of showing a control that cannot work.
Permissions and platforms
- Windows: the source includes native window enumeration and capture.
- macOS: attaching an app requires macOS 14 or later and Screen Recording permission.
- Reading interface text: Accessibility permission may also be required, and some applications expose no readable interface structure.
- Protected windows: the operating system can permanently reject capture; retrying will not change that result.
After granting macOS permission, the already-running EvoX process may still need to be restarted before it can capture the window.
Give a bounded instruction
After attaching the window, state the goal, allowed actions, and stop conditions.
Read the release board in this window and list items due today that have no owner.
Do not click, edit, or submit anything.
For Operate, name the controls that may be clicked or filled and require confirmation before submitting, deleting, paying, sending a message, or leaving the selected window.
Privacy and limits
Choose only the window required for the task and hide unrelated notifications, customer information, and verification codes first. Read adds interface text to the same message context as the image. Operate also permits in-window input, so it needs a tighter boundary than an ordinary image attachment.
For one static screenshot, Image input is simpler. See Computer use for the current status of full desktop control.
