Paste text below to see roughly how many tokens it is, and what a request that size would cost across Claude's current models. Nothing you paste is sent anywhere - this runs entirely in your browser.
Output length defaults to roughly match your input - edit it if you expect a much shorter or longer reply. Token counts here are an estimate (~4 characters per token, per Anthropic's own rule of thumb) - actual counts vary by content and language, usually within about 10-15%.
