Use looot to write spintax for this email: [paste the email]. 1. Set up https://looot.ai/skill.md. 2. Add {a|b|c} choices to the greeting, the first line and the call to action, with 2 or 3 options each that keep the meaning. 3. Check every brace is closed. 4. Return the spintax and 5 sample variants.

## What it needs

Text with {option|option} blocks and how many variants you want

## What comes back

- the unique variants
- how many distinct texts the spintax can make
- the position of any syntax error

## Endpoints and providers

None. The tool on the web page runs in the browser and calls no endpoint.

## What it costs

Nothing. The tool on the web page runs in the visitor's browser: no account, no API call and no limit per hour. The prompt above runs the same job from your own looot account with current data, billed per call.

## Vary cold emails

Send a slightly different text to each lead from one template.

## Test wording

See every combination of a subject line before you pick one.

## Catch broken spintax

Find an unclosed brace before your sending tool prints it as is.

## Export variants

Download the variants as a text file, one per block.

## What is spintax?

A way to write several versions of a text at once. {Hi|Hello|Hey} means pick one of the three. A tool then builds the variants by picking one option from each block.

## How do I use this spintax generator?

Paste your text with {option|option} blocks, set how many variants you want and they appear at once. Copy them all or download them as a text file.

## Does it support nested spintax?

Yes. A block can hold other blocks, such as {Hi {there|team}|Hello}. Every level is spun.

## How many variants can it make?

Up to 500 per run. It also shows how many distinct texts your spintax can make in total, so you know if you asked for more than exist.

## How are duplicates removed?

Two different picks can give the same text, for example when two options are the same. Every variant is compared and only unique ones are kept.

## How do I write a literal brace or pipe?

Put a backslash before it: \{, \} or \|. The backslash is removed in the output.

## Is this spintax generator free?

Yes. It runs in your browser with no account and no limit. Nothing you type is sent anywhere.
