  1. 1

    Paste gappy text

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

Difference vs Remove Empty Lines?
Remove Empty Lines deletes ALL blanks; Collapse keeps a single blank between paragraphs so structure survives.
Do space-only blank lines count?
Yes — lines containing only spaces/tabs are treated as blank before collapsing.
Is exactly one blank always kept between paragraphs?
Yes — consistent single-gap structure is the goal.
Private?
100% local, as with every Toolflect Text Tool.
