Spintax generator

Spintax (spin syntax) is a template format that describes many variations of a text in one string. Options are written inside curly braces separated by pipes, and each generated version picks one option from every group. It is useful for creating message variants for A/B tests, sample data for UI testing, chatbot replies and varied notification texts.

How to use it

1. Write a template with option groups, for example {Hi|Hello|Hey} {there|friend}!
2. Generate one or many variations.
3. Copy the results.

Syntax

• {a|b|c} picks one of a, b or c.
• Groups can be nested: {Good {morning|evening}|Hello} produces Good morning, Good evening or Hello.
• Text outside braces stays the same in every variation.

How many variations?

Multiply the number of options in each independent group. {Hi|Hello|Hey} {there|friend}, {thanks|thank you} for {joining|signing up}! has 3 × 2 × 2 × 2 = 24 possible variations.

Good uses

• A/B testing subject lines and calls to action to see which wording performs better.
• Test data: generating varied names, sentences or labels to check layouts with different text lengths.
• Conversational interfaces: making bot replies feel less repetitive.

What to avoid

Spinning articles to mass-produce near-duplicate pages for search engines is considered spam by Google's policies and can get a site penalised. Similarly, using spintax to evade spam filters in bulk unsolicited email is against anti-spam laws and provider policies. Use variations to test genuine messages, not to disguise duplicate content.
