What is AINoter?
AINoter is a macOS utility that lets you capture AI prompts directly from any application on your Mac. Instead of manually typing out or copying prompts you've written in ChatGPT, Claude, or other AI tools, AINoter intercepts and copies them with a single action. This is particularly useful for people who experiment with different prompts across multiple apps and want to build a personal library of effective prompts. The tool works as a background utility, making it easy to collect prompts without interrupting your workflow. Since it's free, it's a straightforward way to keep track of prompts that work well for your needs.
