Who is this for?

Bloggers and content creators can add a live character counter directly to their write-up page so readers can check platform limits without switching tabs.

Educators and course authors can embed the counter inside a lesson, letting students practise writing to length constraints as part of the exercise.

Developers can drop the widget into any CMS, documentation page, or internal tool with a single <iframe> — no API key, no account, no build step required.
