Cursor Terminal AI Not Working — How to Fix Ctrl+K in Terminal

Cursor's terminal AI feature lets you generate shell commands using Ctrl+K directly inside the integrated terminal, but many users find it unresponsive, missing, or failing to produce output. This issue commonly affects users on older Cursor versions or those who have not explicitly enabled the feature in settings. Developers on free or limited plans may also find terminal AI gated behind an upgrade requirement.

Why does this error happen?

The terminal AI feature (Ctrl+K in terminal) was introduced in Cursor version 0.40 and is not available in earlier builds. Even on supported versions, the feature ships disabled by default in some configurations and must be toggled on manually in the settings panel. Additionally, the integrated terminal process occasionally caches a stale session state that prevents the AI layer from attaching correctly, meaning a restart of the terminal — not just the editor — is required. Finally, Cursor's terminal AI is a plan-gated capability, so accounts without an active Pro or Business subscription may see the shortcut silently do nothing or display a plan-upgrade prompt.

How to fix it

Update Cursor to Version 0.40 or Later

Open Cursor and navigate to Help > Check for Updates to confirm you are running version 0.40 or higher. Terminal AI does not exist in earlier releases, so no setting change will enable it on an outdated build. Download the latest installer from cursor.sh if the in-app updater is unavailable.

Enable Terminal AI in Cursor Settings

Go to File > Preferences > Cursor Settings (or press Ctrl+Shift+J) and search for 'terminal AI' in the settings search bar. Toggle the 'Enable Terminal AI (Ctrl+K)' option to the on position if it appears disabled. Save your settings and confirm the change has persisted by reopening the settings panel.

Restart the Integrated Terminal

Close every open terminal tab inside Cursor by clicking the trash icon on each panel, then open a fresh terminal with Ctrl+` or via Terminal > New Terminal. This forces the AI layer to re-attach to the new terminal session and clears any stale process state. Try pressing Ctrl+K again in the new terminal to verify the prompt appears.

Check if Terminal AI Is Available on Your Plan

Navigate to your Cursor account dashboard at cursor.sh/account and review which features are included in your current subscription tier. If terminal AI is listed as a Pro feature, the shortcut will not function on a free account regardless of settings. Upgrading to Cursor Pro unlocks terminal AI along with increased request limits and advanced model access.

Pro tip

Pin your Cursor version to auto-update by enabling automatic updates under Help > Preferences > Auto Update so that new terminal AI improvements and bug fixes are applied without manual intervention.

Frequently asked questions

Why does Ctrl+K do nothing when I press it in the Cursor terminal?

Ctrl+K in the terminal is only active when the terminal panel has focus and the terminal AI feature is both enabled in settings and available on your plan. Click directly inside the terminal panel to ensure focus is correct, then verify the feature toggle is on in Cursor Settings.

Is Cursor terminal AI available on the free plan?

Terminal AI is a Pro-tier feature in Cursor and is not fully available on the free plan beyond any trial usage. You will need an active Cursor Pro subscription to use Ctrl+K command generation in the integrated terminal consistently.

Does terminal AI work in external terminals like iTerm2 or Windows Terminal?

No, the Ctrl+K terminal AI feature is exclusive to Cursor's built-in integrated terminal and does not extend to external terminal applications. You must use the terminal panel embedded within the Cursor editor window to access this functionality.

Can I change the Ctrl+K shortcut for terminal AI to something else?

Yes, you can remap the terminal AI keybinding through File > Preferences > Keyboard Shortcuts by searching for the 'terminal.ai.generateCommand' action. Assign any preferred key combination that does not conflict with existing terminal shortcuts.
