Privacy: your text never leaves your browser

Every Toolflect Text Tool is 100% client-side. The moment you type or paste text, it is analyzed by JavaScript running inside this browser tab. Your text is never sent to our servers, never stored in a database, and never shared with any third party or AI service. Visit counting (see the note at the foot of this page) is separate from your text and never receives it.

  • No uploads, no accounts, no sign-up
  • Your text is processed locally in your browser and never stored.
  • Works offline once the page has loaded
  • Close the tab and your text is gone from memory

You can even verify it yourself: open your browser's developer tools, switch to the Network tab, and type into the tool — no request ever carries your text. You will also see the Google Analytics request that counts the visit; it carries a page view and never anything you typed, and no cookie or identifier is stored until you accept analytics.

Frequently asked questions

How are words separated in the result?
With single spaces — punctuation attached to a word travels with it ('apple,' ≠ 'apple').
Does case matter by default?
No — matching is case-insensitive unless you tick Case-sensitive matching.
Can I get an alphabetical list?
Yes — choose Sort A→Z (or Z→A) in Result order; dedupe always happens first.
Is my keyword list uploaded?
Never — everything runs locally in your browser.
Can I use it as a duplicate keyword remover?
Yes — paste a keyword list or prose and it removes repeated words, with a case-sensitive toggle and optional A→Z sorting of the unique result.
