This site does one thing: it turns normal text into upside-down Unicode text you can paste anywhere. No account, no app download, no tracking your keystrokes anywhere else — everything runs directly in your browser.
It started as a small side project to make a genuinely fast, ad-light version of a tool that's usually buried under pop-ups. The character mapping is built on standard Unicode blocks, mainly the International Phonetic Alphabet, which is why the output displays correctly across nearly every modern app and platform.
If you spot a character that doesn't flip the way you'd expect, or a platform where the output breaks, let us know — the mapping gets refined over time based on real feedback.
