Text

Switch text between upper, lower, title, camel and snake case.

Count characters with and without spaces.

Pull every email address, phone number and link out of a messy paste — deduplicated, and without the trailing full stops.

Turn a page or an editor's output into clean Markdown — walking the parsed DOM, not matching tags with patterns.

What is in both lists, what is only in one — matched properly, so a trailing space does not hide a row.

Render Markdown to HTML with raw HTML escaped rather than passed through — because pasted text is untrusted text.

Turn any title into a clean URL slug.

Clean up a list: sort it, remove repeats, drop blanks — with alphabets that sort correctly.

Fix text that has been through a PDF, an email client or a word processor — one decision per switch.

Compare two blocks of text and see exactly which lines were added, removed or changed.

See every character for what it is — including the ones you cannot see, which are usually the problem.

Count words, sentences and reading time as you type.
