How does the Word Combiner work?

It computes the Cartesian product (cross-multiplication) of your word lists. Every item in List A is combined with every item in List B, and optionally List C, using your selected separators.

Can I use this for domain name ideas or SEO keyword mapping?

Yes, absolutely. By combining prefixes, keywords, and suffixes with no space or hyphens, you can generate thousands of domain ideas or search keyword variations instantly.

Is my text data private?

Yes. The list merge computations execute locally inside your browser memory context. No words are ever sent to a server.

Frequently Asked Questions

What is the Cartesian Product list merge? +

The Cartesian product combines every line of List A with every line of List B, and then with every line of List C. If lists contain 10 lines each, it yields 1,000 combinations (10 x 10 x 10).

How does custom separator logic work? +

Selecting "Custom separator..." displays an input box where you can specify any string (e.g., dots, symbols, slashes) to join the terms.

Is there a limit on combinations? +

Since computations execute in local browser memory context, generating up to 50,000 combinations is handled smoothly. We cap computations to avoid browser freezes.
