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.

  • No uploads, no accounts, no sign-up
  • No cookies or tracking of your text
  • 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 — the only requests you will ever see are this page's own static files (HTML, CSS, JavaScript). Nothing you type is ever transmitted.

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.
