Spintax tool
Write {one|two|three} once, get every variation. Count the combinations, pull a batch of unique spins and check for broken braces.

Generate spins
“Avg. uniqueness” is the mean word-level difference between the returned spins — higher means the variations differ more. It is a rough guide, not a plagiarism score. Spun text still reads as spun to a person and to modern classifiers; use it for volume, not to disguise thin content.
What spintax is for
Spintax is a shorthand for text with interchangeable parts, written with braces and pipes: {Play|Sign up|Join} expands to one of "Play", "Sign up" or "Join". Groups can be nested, and a template with a few groups produces thousands of variants. This tool expands nested spintax, counts the exact number of combinations, reports the spin-group count and maximum nesting depth, generates a batch of unique spins with a word-level uniqueness estimate, and flags unbalanced braces. It is used to rotate ad creatives, personalise outreach messages, and vary comment or forum text at volume.
It does not make thin content unique
Spun content does not help SEO the way it did years ago. Search engines and ad classifiers detect spun, low-information text easily, and near-duplicate pages built from spintax get filtered or penalised. Use it for legitimate variation, not to fake unique content. The uniqueness percentage here is the average share of words that differ between the returned spins — a rough guide, not a plagiarism score; a low number means your options are near-synonyms and the spins read almost the same. If you ask for more spins than the template can produce, the generator returns fewer, because it only returns unique results.
