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 is this different from remove-duplicate-words?
Remove Duplicate Words (Group 4) outputs a deduplicated version of your text. This tool COUNTS your unique vocabulary and reports the ratio — a measurement, not a transformation.
Is counting case-insensitive?
Yes — 'The' and 'the' are the same unique word, matching standard vocabulary analysis.
What is a good uniqueness ratio?
Higher generally means richer vocabulary, but the ideal depends on genre. The ratio is a diagnostic, not a score.
Private?
Fully — the analysis runs locally in your tab.
