Paste at least two versions, a sentence or more each. Words are compared three at a time, so very short texts can't be compared.

How it works

Short and checkable: every limit links to the platform's own page, read on 28 Oct 2026.

  1. Words are compared three at a time

    Each text is cut into every run of three words, accents and capitals ignored. Copy a sentence and all its runs match; rewrite it and almost none do. Moving a sentence to another place doesn't hide it.

  2. Each version is measured against the others

    "B shares 34 % with A" means 34 % of B's three-word runs also appear in A. It is not always the same both ways: a short version inside a long one shares a lot, the long one much less. The headline shows the higher of the two.

  3. The 40 % line is ours, not the platforms'

    It is the line Vertiscale's studio uses before it calls a new angle its own video — the same measure it runs on each new angle or language version. Platforms publish no percentage. They do say what they push down: Instagram stops recommending accounts that mainly repost, and YouTube won't monetize content that feels interchangeable.

What it doesn't do

  • It reads words only. Two videos with the same pictures, music or edit can still look alike to a platform.
  • It doesn't translate: an English and a French version of the same script share almost no words, yet tell the same story.
  • Nothing is sent or saved. The texts stay in this tab.

Questions

Can I post the same video on several accounts?

Not safely. Instagram cut the reach of accounts that repost content (April 2026) and YouTube's Partner Program excludes reused and inauthentic content. Each account should get its own version.

How different do two versions need to be?

No platform publishes a number. This tool shows how much of each version repeats the others, phrase by phrase, so you can rewrite the parts that are shared.

What does the percentage mean?

The share of three-word sequences two texts have in common. 0 % means no phrase of three words is shared; 100 % means the same text.
