 # Invisibles
 
-Some text carries characters you can't see: zero-width spaces, non-breaking spaces that aren't real
-spaces, direction controls, the odd characters that ride along in text copied out of an AI.
-Invisibles shows you what's hiding and strips it, all in your browser.
+Paste text, see every hidden character in it with its name and code point, then
+click once to strip them. Zero-width spaces, non-breaking spaces that look like
+real ones, direction controls, the odd characters that ride along in text copied
+out of an AI.
