FAQ

Is the widget really free?

Yes. Use it on personal or commercial sites at no cost. We just ask that you keep the small attribution link below the iframe — it's how we keep the tool free for everyone.

Does the widget collect data on my readers?

No. All character counting runs locally in your reader's browser. We don't set tracking cookies on the embed.

Will it slow my page down?

Negligible. The iframe lazy-loads, and the page inside is a few KB of static markup with no analytics or third-party trackers in the embed itself.

Can I customize it further?

The query parameters above cover the common cases (theme, size, focused platform). For deeper customization, link to a specific tool page like /twitter-character-counter and embed that instead.

What about WordPress / Ghost / Substack?

Use a Custom HTML or Embed block, then paste the snippet. Some hosted Substack/Medium plans block iframes — link to the tool directly in those cases.
