Every "clean up this text" tool is a website you paste sensitive data into that is manual, token-burning, and privacy-leaking. PipeCleaner is a Mac app that does it locally, zero network connections. Copy a messy terminal table or log, get clean Markdown, CSV, Excel, or Word. Flip on Auto-Clean and terminal copies are fixed the instant you hit ⌘C. Plus a CLI, Services menu & Shortcuts. Built because I got tired of hand-fixing every table I pasted into Teams & GitHub.
