Frequently asked questions
What is alternating case?
Alternating case switches between lowercase and uppercase letters, such as aLtErNaTiNg. Online it is often used to show a mocking or sarcastic tone.
What does restart on each word mean?
With it on, each word begins with the same case, so every word starts small, for example hElLo wOrLd. With it off, the pattern runs across the whole sentence without restarting.
What is inverse case?
Inverse case swaps every letter: capitals become small and small letters become capitals. It quickly fixes text typed with Caps Lock on by accident.
Is random case really random?
Each letter is set to upper or lower case by chance, so the result changes every time you type. Press Use as input and edit if you want to freeze one version.
Will it work on Instagram, WhatsApp and TikTok?
Yes. The result uses normal letters, so it works anywhere you can type, unlike special Unicode fonts.
Do numbers and emoji change?
No. Only letters are affected. Numbers, emoji, spaces and punctuation stay the same and are skipped in the pattern.
Is alternating case hard to read?
Yes, especially for people using screen readers, which may read it letter by letter. Keep it for short, playful messages.
Where did the alternating case meme come from?
It became popular around 2017 with a meme showing a cartoon character acting like a chicken, captioned in alternating letters to mock what someone else said. The style is still used to show sarcasm in replies.
Can I convert a whole paragraph at once?
Yes. Paste as much text as you like, and every line is converted while keeping your line breaks, so long messages and lists keep their layout.
Is my text saved anywhere?
No. The conversion runs in your browser and nothing is sent to a server.
How this tool works. These text tools run entirely in your browser with plain JavaScript, so the text you paste never leaves your device and results update as you type. Each tool is tested with real text such as copied PDFs, emails, code, lists, emojis and non-English scripts before it goes live.
