Why use browser based text and writing tools

Writing work generates a constant stream of small text chores. A word count against a strict brief. A case change across a list of headings. Duplicate lines stripped out of a research dump. Smart quotes normalised before a paste into a code block. These text and writing tools each solve one of those chores and get out of the way.

Because processing happens in the browser there is no character limit imposed by an upload size, and unpublished manuscripts or client copy are never transmitted anywhere. Paste a hundred thousand words and the counter still updates as you type.

Frequently asked questions

Yes. Every tool in this category is free with no account, no trial and no daily limit. The tools run as JavaScript inside your own browser, so there is no server cost to pass on and no reason to meter usage.

No. Files are read directly from your device into browser memory, processed locally and written back out as a download. Nothing is transmitted, nothing is logged and nothing is stored after you close the tab.

There is no limit imposed by us. The practical ceiling is your own device memory, because the file has to fit in the browser tab while it is being processed. Most machines handle files of several hundred megabytes without trouble.

Current versions of Chrome, Edge, Firefox and Safari on desktop and mobile are all supported. Where a specific tool depends on a capability that a browser has not shipped yet, that tool says so on its own page before you select a file.
