See it.
Bring your current screen into context.
Press ⌘⌥K and kk opens over whatever you're reading. The display under your cursor comes along; preview it, or drop it, before you send.
Circle it.
Ask about it.
kk lives in your Mac's menu bar. Press ⌘⌥K, mark up whatever's on your screen, and ask your own AI model about it. The answer appears right beside the app you're using.

An animated recreation of kk. In a code editor, kk opens with Command Option K, the line tags equals empty list is circled in red, the question “Why does the second call keep the first tag?” is sent, and an answer explains Python's shared mutable default argument. A follow-up asks for the safe version and kk replies with corrected code.
Press ⌘⌥K in any app. kk opens over whatever you're doing.
Recreated interface with sample content, based on kk's own previews.
Three moves, one shortcut.
Everything starts with ⌘⌥K. No browser tab, no pasting screenshots into a chat window.
02 / 03
Mark it.
Circle, highlight, or point at exactly what matters.
Draw straight onto the screen with freehand, ellipse, rectangle or arrow. Marks can be moved and resized; they're sent with the screenshot, their handles aren't.
03 / 03
Ask away.
Get answers and continue the conversation.
Answers stream in with real math, code and tables. Move your mark, ask again, and the follow-up sees the updated screen.
Staged native renders from kk's README. The problem set and answers are sample content.
For the questions you'd otherwise screenshot.
One shortcut, one popup, and a red pen. Everything else is there to keep you in the app you were already using.
Mark it like you mean it.
Freehand, ellipse, rectangle and arrow, plus an eraser. Drag a mark to move it, resize from its handles, undo anything. Draw over a frozen snapshot or the live desktop.
Go ahead, scribble on the build log. With the canvas focused, the same tool keys work here: VFERAX

Your model. Your key. Your endpoint.
kk is the window, not the brain. Bring whichever model you like, and requests go straight from your Mac to the endpoint you choose.
- OpenAI-compatible
- Any endpoint that speaks streaming Chat Completions. Use a vision-capable model for questions about your screen.
- Cloud or local
- Point kk at a hosted provider, or at a model server running on your own Mac.
- Your key, in Keychain
- Stored in macOS Keychain. Optional for endpoints that don't need one.
- No kk account
- No sign-up, no subscription. kk doesn't sell or proxy inference; usage is billed by your provider, where applicable.

Less switching.
