Text Tools

Why use text tools in the browser?

Most people reach for a desktop editor or a website that uploads their text to a server just to count words or change capitalisation. That is unnecessary friction, and for anything you'd rather not share — a draft contract, personal notes, unpublished work — it is also a privacy risk.

Every tool on this site runs locally, using your browser's own JavaScript engine. When you paste text into the word counter or the case converter, the text is processed in memory on your device and disappears when you close the tab. There is no upload, no account, no storage on our side, and no size limit beyond what your device can handle.

The practical benefits show up immediately: results appear as you type rather than after a round trip, the tools work offline once the page has loaded, and you can paste thousands of lines without waiting.

How it works

Each tool is plain JavaScript running in your browser tab. When you paste text, it stays in that tab's memory: it is processed on your own CPU, rendered back to you, and discarded the moment you close the page. There is no upload step, no queue on a server, no account to create, and no file-size cap imposed by us. That's why results appear instantly even on a large document — there is no network round trip to wait for. It also means the tools keep working if your connection drops after the page has loaded.

Which tool should I use?

• Word Counter — check length against a word limit, estimate reading time, or track character counts for social media posts.
• Case Converter — fix inconsistent capitalisation in titles, headings, CSV columns, variable names or shouty forum posts.
• Duplicate Line Remover — clean up email lists, keyword lists, log entries or any pasted column of data.
• Find & Replace — rename terms across a document, strip patterns with regular expressions, or tidy formatting in bulk.
