Hi HN. I built ClipMason because clipboard managers just store text - I wanted one that actually does things with what I copy.
I'm a developer and I constantly copy code, URLs, hex colors and screenshots.
I was tired of switching between tools to format JSON, encode Base64, resize an image or run OCR on a screenshot.
ClipMason sits in the menu bar and detects what you copy. Depending on the type, it shows relevant actions:
- Text (22+ actions): case conversion, camelCase/snake_case, JSON pretty print, Base64, URL encode, MD5/SHA-256, sort/deduplicate lines
- Images: resize (percentage or exact pixels), rotate, flip, grayscale, invert, annotate, OCR
- Colors: detected automatically from hex strings, copy as HEX/RGB/HSL/SwiftUI/CSS
- URLs: open in browser, extract domain, convert to Markdown
- Files: open, reveal in Finder, copy path Built natively with SwiftUI and SwiftData. No Electron. Everything stays local on your Mac.
Happy to answer questions or hear what other actions would be useful.
