Word counting, case conversion & text cleanup

What are text tools?

Text tools handle the small, repetitive edits that happen constantly while writing, editing, and cleaning up content — counting words for an assignment, converting a heading to title case, stripping duplicate lines out of a list, or catching a grammar mistake before hitting send. None of these tasks are complicated on their own, but doing them by hand is slow and error-prone, especially with anything longer than a paragraph. A dedicated text tool does the job in a fraction of a second and gets out of the way.

Every tool in this collection processes text directly in the browser using JavaScript's built-in string handling — nothing is uploaded to a server first. The word counter and character counter update live as text is typed or pasted in, the case converter and slug generator transform text instantly on input, and tools like the duplicate line remover and text sorter run the moment a block of text is dropped in. There's no waiting, no file size limit tied to an upload, and no delay between typing and seeing a result.

Who uses these tools, and for what

Writers and editors lean on the word counter and character counter to hit exact length requirements for essays, captions, and meta descriptions, while the grammar checker and text cleaner catch typos and stray formatting before publishing. Developers use the find-and-replace tool and duplicate line remover to clean up config files, CSV exports, or log output. Marketers and SEO writers reach for the slug generator to turn a page title into a clean URL, and the lorem ipsum generator to fill a layout with placeholder copy before real content is ready. The word frequency counter helps anyone checking for repetitive phrasing or keyword density in a longer piece of writing.

Why they're free, fast, and private by default

Text often contains something that shouldn't be pasted into a random website — a password reset link, a client's draft contract, an unpublished article. Every tool here is built with that in mind: text is only ever processed locally in the browser tab, never sent to a server, logged, or stored. That also means results appear instantly, since there's no network round trip involved, and the tools work the same whether the text is a single sentence or several thousand words.

That combination — free, instant, and private — is what makes a text tool worth reaching for instead of doing the edit by hand. No signup, no upload limit, and no reason to think twice about what's being pasted in. New text tools are added to this category as they're built.
