Text tools

Count words, change case, clean up lists, compare text and preview Markdown. Every tool runs in your browser, so nothing you add is uploaded.

Count & analyze

Word, character, sentence and paragraph counts, with reading time.

Word Counter

Counts words, characters, sentences and paragraphs as you type, and estimates reading time.

Change case & format

Switch between upper, lower, title and sentence case, programming styles such as camelCase, and URL slugs.

Case Converter

Changes text to UPPER CASE, lower case, Title Case, Sentence case, camelCase, snake_case, kebab-case and more.

Slug Generator

Turns titles into clean, URL-friendly slugs, removing accents, punctuation and spaces.

Compare

See exactly what changed between two versions of a text.

Text Diff

Compares two versions of text and highlights added, removed and changed lines and words.

Clean up lists & spacing

Remove duplicate or empty lines, sort lists, and fix extra and invisible spaces.

Remove Duplicates

Removes repeated lines from a list, keeping the first copy of each and the original order.

Sort Lines

Sorts lines alphabetically, naturally (2 before 10), by length, in reverse, or shuffles them.

Remove Extra Spaces

Cleans up messy spacing: double spaces, spaces at line ends, extra blank lines and invisible characters.

Remove Empty Lines

Deletes blank lines from text, including lines that contain only spaces.

Markdown

Write Markdown for README files, docs and notes, and see it formatted as you type.

Markdown Previewer

Shows Markdown formatted as you type, with tables, task lists and code blocks, and exports it as HTML.

About Text tools

Everyday helpers for writing and working with lists: count words and characters for essays and posts, fix text typed with Caps Lock on, compare two versions of a document, remove duplicates from a list, clean up the messy spacing that comes with text copied from PDFs and websites, and preview Markdown as you write it.

Results update as you type or paste, and nothing you enter is stored or sent anywhere, so the tools are safe for drafts, contracts and private notes.

Frequently asked questions

Is my text saved anywhere?

No. Text is processed in your browser as you type, and it is gone when you close the page.

Do the tools work in other languages?

Yes. Counting, sorting and case changes follow the rules for each language, including languages without spaces between words, such as Chinese and Japanese.

How much text can I paste?

Hundreds of thousands of lines work on a typical computer. Very large texts update after a short pause to keep typing smooth.
