Quilt

Quilt is a macOS app that helps you turn anything on your screen into a clean, searchable PDF. Whether you're reading an eBook, flipping through slides, or reviewing a textbook, you can capture it all with just a few key presses or mouse clicks. Quilt takes screenshots for you at set intervals and even interacts with the app by pressing keys or clicking, so you don't have to.

You get full control over what and how you capture. Set countdowns, choose specific areas, and preview everything before exporting. When you're done, export your captures as a PDF, images, or even a GIF. It works offline, keeps your data private, and just does what you need without getting in the way.
