Spintax Generator
Parse nested spintax, get the exact unique variation count, list every version or generate random unique spins, and merge existing variants back into spintax.
Choose a button above to expand your template. Randomness runs only when you click, so the page always loads the same way.
The variation count is the exact product of the branch counts at every nesting level, not an estimate. Random spins are drawn with crypto.getRandomValues and weighted by subtree size so each unique variation is equally likely. Everything runs in your browser — no template text is uploaded.
What is the Spintax Generator?
A spintax tool that parses nested {a|b|{c|d}} syntax with a recursive-descent parser, reports the exact number of unique variations as the product of branch counts, and expands the template into every variation or a set of random unique spins.
- Recursive-descent parser handling unlimited nesting
- Exact variation count — the product of branch counts, not an estimate
- Random spins weighted by subtree size and drawn from crypto.getRandomValues
- Full enumeration in a deterministic order, with a safety cap
- Reverse mode merges pasted variants back into spintax word by word
- Clear errors on unbalanced braces; copy or download the output
How to use the Spintax Generator
- 1
Paste or write your spintax template, nesting groups freely and escaping literal braces with a backslash.
- 2
Check the unique variation count and group count in the stat row — a parse error appears immediately if a brace is unbalanced.
- 3
Click Generate random spins for a set number of unique outputs, or List every variation to expand the whole template.
- 4
Copy the results or download them as a text file.
- 5
Switch to reverse mode to merge existing variants back into a template instead.
About the Spintax Generator
Spintax packs many versions of a message into one template: {Hi|Hello|Hey} there produces three sentences from one line. This tool parses that syntax properly — including nesting, so {a|b|{c|d}} works — and tells you exactly how many unique variations exist, calculated as the product of the branch counts at every level rather than estimated.
From there you can list every variation in a deterministic order, or generate a set number of random unique spins. Random selection is weighted by how many variations each branch contains, so every unique output is equally likely even in deeply nested templates, and it is drawn from crypto.getRandomValues rather than Math.random.
A reverse mode goes the other way: paste several versions of the same sentence and it compares them word by word and merges the differing positions back into a spintax template. Unbalanced braces produce a clear error rather than silent nonsense, and nothing you type is uploaded.
Frequently asked questions
What is spintax?
Spintax is a shorthand for writing many variations of a piece of text at once. Alternatives go inside curly braces separated by pipes, so {Hi|Hello} there produces two sentences. Groups can be nested inside other groups for finer control.
How many variations does my spintax produce?
Multiply the number of options in each group together, treating a nested group as the sum of its own branch counts. {Hello|Hi|Hey} {world|{there|friend}} gives 3 × 3 = 9 unique variations, which is exactly what this tool reports.
Can spintax be nested?
Yes, and this parser handles it to any depth. A nested group like {a|b|{c|d}} contributes four branches to its parent, because the inner group itself expands to two. Escaping a literal brace with a backslash keeps it as plain text.
Is spun content good for SEO?
Not as a way to mass-produce web pages — search engines treat that as spam. Spintax is genuinely useful for varying outreach templates, ad copy variants, alt text and social captions so that repeated messages do not read identically.
How do I turn my existing variations back into spintax?
Switch to reverse mode and paste your versions one per line. The tool compares them word by word and braces the positions that differ. They need the same word count, so trim them to matching length or merge them in smaller groups.
