Text Tools

Working with text often means the same repetitive chores — fixing capitalization, comparing two versions, generating placeholder copy, or clearing duplicate lines. Our Text Tools put these everyday utilities in one place that runs entirely in your browser, so your writing never leaves your device.

Switch letter case in a click, spot the exact differences between two texts, produce Lorem Ipsum for mockups, dedupe a messy list, and analyze structure — without juggling several single-purpose websites.

Text Tools

A quick suite of text utilities: change letter case, compare texts, generate Lorem Ipsum, remove duplicate lines, and analyze text — all running locally in your browser.

100% local — no data ever leaves your browser.

How to use the text tools

  1. 1 Choose a utility from the tabs: Case, Compare, Lorem, Dedupe, or Analyze.
  2. 2 Paste or type your text into the input area.
  3. 3 For case, pick UPPERCASE, lowercase, Title Case, or Sentence case.
  4. 4 For compare, paste two versions to see the line-by-line differences.
  5. 5 Copy the result — everything is processed locally and never uploaded.
