Typing out text you can see on screen is a pain. Synapse's built-in OCR lets you drag-select any region — a screenshot, a scanned PDF, a YouTube video, anything — and instantly extracts all the readable text. Powered by Apple's Vision framework, it works entirely on-device with no data sent anywhere. Free users get 2 extractions per day; Pro users get unlimited.
