What it does

TextDiffy is a free browser suite for text comparison, word counts, case conversion, duplicate removal, line sorting, reversal and keyword density.

Use TextDiffy’s Compare Text route to see highlighted changes between two versions; the document-similarity report answers a different question. For a list, choose alphabetical, numeric or length sorting according to the order needed. Reversal also has a unit: reversing characters, words or whole lines gives different results. The site describes output updating as text is entered. Its tools are free without signup, and the publisher says text processing stays in the browser.

How the SI Score works →

Unconfirmed details may be unassessed, absent from the pages checked or temporarily unreadable. A missing price does not mean the service is free.

Sources and checks

Supporting pages for product usefulness, site facts, prices and separate website checks. Each record keeps its own date. Reading a page does not establish how well the product performs in use.
