Frequently Asked Questions

Can I embed tools for free?

Yes. Copy the iframe from a tool page, or use the demo above. The embed is the full tool page, so it includes this site's header, footer, and ads. No account.

Is there a paid or unbranded plan?

No. There is nothing to buy, no license key, and no way to remove branding or ads.

Do the tools work on mobile?

The tools are built for a phone-width page. An iframe uses the width you give it.

Is there an API?

No. The tools run in the browser. There is no REST API and no webhook.

Which tools have an embed box?
