Why Count Tokens?
Understanding token counts helps you optimize API usage and control costs.
Estimate Costs
Know how much an API call will cost before you send it. Avoid unexpected bills by checking token counts upfront.
Stay Within Limits
Each model has a context window. Check if your text fits before making a request and avoid truncation errors.
Optimize Prompts
Shorter prompts cost less and leave more room for responses. Find the right balance between context and output.
Private Processing
Your text stays in your browser. Nothing is sent to any server. Count tokens for sensitive content safely.
