What these tools are for
Most text chores are small but fiddly: checking an essay against a word limit, fixing a heading's capitalization, turning a column of spreadsheet values into a clean, deduplicated list, or working out exactly what changed between two drafts. Each tool here handles one of those jobs, updates as you type, and doesn't need an account.
Writers tend to reach for the word counter, case converter, and diff checker. Developers and anyone working with data usually get more out of find and replace (with full regular expression support), the line sorter, and the Markdown and HTML converter. Designers use the Lorem Ipsum generator to fill layouts before the real copy exists.
Because nothing you paste is sent to a server, the tools are safe to use with drafts, internal documents, and other text you'd rather not upload. The guides go deeper on the questions these tools raise, from title case style rules to how diff algorithms decide what changed.
