Embed a free AI token counter
Drop the token counter into any blog, docs site, or knowledge base. Free, no signup, no key. Pick a model, theme, and size; copy the snippet.
Why embed an AI token counter?
If you write about LLM cost or tokenization, your readers usually leave your page to check a counter. The embed keeps them where they are, while crediting the tool back to howmanytokens.io. No tracking, no ads in the widget, no signup required.
Prefer to link out instead? Point readers at the full AI token counter and cost calculator, the cheapest AI model ranking, or a specific model page like GPT-5 or Claude Opus.
Attribution
The widget shows a small Powered by howmanytokens.io link in the bottom-right. Please keep it — it's the only ask in exchange for free hosting. If you have a specific use case where the link causes a problem (e.g., a printed PDF), get in touch.
