Why optimize prompt tokens?

Claude API pricing is based on input and output tokens. Shorter prompts mean lower costs, faster responses, and more room in the context window for the actual conversation. Common filler phrases like "please", "could you", and "in order to" add tokens without improving Claude's understanding.

How token estimation works

This tool estimates tokens at approximately 4 characters per token, which is a good approximation for English text. Actual token counts may vary slightly — use the Claude Token Counter for a more precise estimate.
