Wavy underline text generator
Wavy underline puts a rippling line beneath your text. It is softer and more playful than a straight rule, and it suits a bio that is meant to feel light rather than formal.
The wave is a combining mark, so it attaches to any script and survives copying between apps as long as the receiving font can draw it.

Frequently asked questions
Does Wavy underline work with non-Latin alphabets?
Yes. Wavy underline adds marks or spacing around whatever you type instead of swapping in look-alike letters, so Korean, Japanese, Cyrillic and emoji all keep working. That makes it one of the few styles that is safe for multilingual bios.
Can I paste Wavy underline text into Instagram?
Yes. These are ordinary Unicode characters, not a font file, so Instagram, TikTok, Discord, X and most other apps accept them in bios, display names and captions. Nothing is installed and nothing expires.
Some letters show up as empty boxes (□).
A box means the device rendering your text has no glyph for that character — the text itself is fine. Older Android builds and some in-app browsers are the usual culprits. Preview your text in the app you are pasting into before you save it, and fall back to a simpler style if it breaks.
