Are the widgets free to use?

Yes. They are free for blogs, classrooms, documentation and personal sites, with no account or key. Keep the link back to the full tool.

Do the widgets track my visitors?

The widgets set no cookies of their own and nothing typed into them is sent anywhere. The typing test, like the main site, reports an anonymous count of finished scores.

Can I change what a widget looks like?

You can change its width and height in the snippet. The design inside the frame is fixed, and it follows the visitor's light or dark setting.

Will search engines index the widget pages?

No. Widget pages are marked noindex so only the full tool pages appear in search results. The visible text link on your page points to the full tool.

Embeddable widgets

Add a working clevr.tools widget to your blog, classroom page, wiki or documentation. Each one is a single copy-paste snippet: no account, no script to install, no cost. Teachers can drop the typing test into a class page; bloggers can give readers a converter right where they need it.

How it works

Pick a widget below and press “Copy embed code”.
Paste the snippet into your page's HTML (most editors have a “custom HTML” block).
Keep the small text link under the widget. It points readers to the full tool and is how we keep these widgets free.

Widgets resize to the width of their container and follow the visitor's light or dark preference. They don't set cookies of their own and nothing typed into a widget is sent anywhere.

Tips for using a widget

Width and height. The snippet uses width 100%, so a widget fills its column. If its content is cut off on a narrow page, raise the height value; the widget scrolls inside the frame rather than overflowing your layout.
Where to paste it. Any editor that accepts raw HTML works: a custom HTML block in WordPress, an embed or code block in Squarespace, Wix or Ghost, or a plain HTML page. Editors that strip iframes can't host a widget.
Light and dark. Widgets follow the visitor's system theme, so they match readers who prefer dark mode.
Keep the link. The text line under each snippet and the “Powered by clevr.tools” link inside the widget are how readers find the full tool.
