The app

One window.
Three things to set up.

Sidebar of actions. OpenRouter key + model on top. A prompt editor for each shortcut. That's the whole app.

caip action editor: title, prompt template, shortcut
Action editor · title, prompt template, hotkey

Three things, done well.

No subscription. No telemetry. No floating window. Just a hotkey, a model, and the text in your selection.

01

Native, not Electron.

SwiftUI + AppKit. ~700 KB on disk. No background services. No always-on hotkey daemon. Boots before you can blink.

02

Hotkey-first.

Any combination of ⌃⌥⇧⌘ plus a key, or a standalone F-key. Each action gets its own shortcut and prompt — grammar fix, translate, summarize, whatever you wire up.

03

Your model, your key.

OpenRouter under the hood. 350+ models from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek and more. Sort by price, context, or recency. Pick the one you trust.
