Transform your clipboard text from the menu bar. Copy text, pick a transform, paste the result. No terminal, no web tools, no context switch.
I was constantly opening a terminal or a website just to uppercase a string, base64-encode an API key, or pretty-print some JSON. It's always the same flow: copy, transform, paste. PasteForge puts 37 transforms one click away in the menu bar. No context switch, no browser tab, no echo | base64.

Verify file hash: Copy file contents, click SHA-256 → hash string
Clean up messy text: Copy text with extra whitespace, click Trim Whitespace → clean text

App doesn't appear in menu bar:
Make sure you're running the .app bundle or the compiled binary, not swift PasteForge.swift (which won't work with @main).
"No text on clipboard" when you've copied something: PasteForge only reads text from the clipboard. Images, files, and other non-text content won't be detected.
Transforms show "[Invalid JSON]" or "[Invalid Base64]": The input text isn't valid for that transform. This is expected behavior — the error message tells you what's wrong.
