Alternating case

What it's really for

It's the «SpongeBob text»: born from a cartoon frame that became a meme, it's used to make clear that what you're writing is a mockery of what someone else just said. Written normally, «sure, that will work great» is a comment; written alternating, it's plainly sarcastic. It exists to carry the tone of voice into text, which is exactly what messages lose.

How it alternates

The count runs on letters, not on characters: spaces, commas and numbers don't skip a turn, so the effect carries on identically from one word to the next instead of restarting each time. It always starts from lowercase, which is the shape the meme is recognized by. Accented letters count like all the others; the ones without an uppercase and a lowercase form, like the German ß or ideograms, stay as they are and don't skip a turn.

Where not to use it

With a screen reader the sentence usually sounds as if it were written normally, because the letters are the real ones; some readers, though, spell out words with capitals in the middle letter by letter, as if they were acronyms, and then a whole sentence turns into noise. It's hard on the eyes too, so it's fine in a comment or a reply, never in a title, a bio or a message that has to be understood at a glance.

Nearby tools

If you simply need to flip the case of a text typed with Caps Lock on, that one is Swap upper/lowercase. To write backwards there is Reverse text and for upside-down letters Upside-down text. If you're after unusual characters for a bio, the collection is in Text with special characters.

The seven special-character pages share the same engine and the same table of styles, so the same text, in the same style, comes out identical on all of them. The other six are Fancy fonts for bio, Fancy text generator, Small caps text, Upside down text, Spaced text and Leet speak translator.
