Anthropic Token Counter
Count Anthropic tokens online and see what your text costs across all 14 models, including Claude Fable 5.1, Claude Fable 5 and Claude Opus 5.5. Everything runs in your browser and nothing you paste leaves the page. Counts are estimates made with the cl100k_base encoding, since Anthropic has not released a browser-ready tokenizer. Estimated counts are marked with a tilde (~).
