Download for macOS

Requires macOS 13 or newer, an OpenAI API key, and Screen Recording permission.

What it does:

• Press a keyboard shortcut to capture your screen.
• Ask a question like “Explain this” or “Where do I click?”
• Get a concise answer, plus optional on-screen guidance.

Privacy:

Sasu only sends your screenshot to OpenAI when you ask a question. It doesn’t have its own server. Your OpenAI API key is stored securely in macOS Keychain.

Why I made this:

I work in Japan and sometimes need help understanding forms, and other web pages. I got tired of taking screenshots, switching to the Finder, and dragging them into chat. The app name is 指す — 'to point.'
