Ready to Paste

Choose a layout

Each snippet is a single <iframe>. Copy it, paste it into your page, and the calculator loads on demand. The loading="lazy" attribute keeps it from slowing down your initial page load.

Full graphing calculator

The complete tool — function plotting, tables, step-by-step working and the keypad. Best for a dedicated calculator page.

Embedding questions

Is it really free to embed?

Yes. There is no API key, no account and no usage limit. The only thing we ask is that the attribution link stays in place — that is what keeps the tool free.

Do I need to credit you?

The iframe carries the attribution by default. If you want to add a text link as well, a line such as “Free graphing calculator” linking back is appreciated but not required.

Will it slow my page down?

No. The iframe uses loading="lazy" so it does not fetch anything until it scrolls into view. Your initial page load is unaffected.

Does it work inside a CMS?

Yes — anywhere you can paste an iframe or an HTML block. That covers WordPress, Ghost, Notion exports, Google Sites and most textbook platforms.

Can I use it in a paid course?

Yes. Free for commercial and educational use, including paid courses and membership sites, provided the attribution link remains.

Does it collect data about my readers?

No. The calculator runs entirely in the reader's browser. Nothing is sent to a server and no cookies are set by the embed.
