Everything on this page is arithmetic on strings, and your browser is already very good at that. Counting words, changing case, finding and replacing, sorting and deduplicating lines, stripping HTML tags, generating a slug, comparing two versions, and measuring keyword density are all operations a few lines of JavaScript can do instantly on your own machine. There is no reason to involve a server, so none of these tools does. Nothing you paste is uploaded, nothing is stored, and there is no length limit beyond what your device's memory can hold; the tools even keep working with the connection off. That is a genuine privacy difference rather than a slogan, because text tools are so often used on drafts, client copy, and pasted documents. None of these needs an account, and none of them is limited. The AI-powered writing tools are a separate category and do send text to a provider.
No — every text tool runs locally in your browser, so your content stays private.
You can paste large amounts of text; the practical limit is your device's memory.
