TokenCalculatorAI makes LLM usage easier to understand by combining token counting, word and character counts, and AI API cost estimation in one simple developer tool. Compare usage across popular models before sending prompts.
I built TokenCalculatorAI after running into a simple problem while working with LLMs: it's easy to write a prompt, but not always easy to know how many tokens it will consume or what that request could cost.
I wanted one simple place to check token usage and estimate API costs before sending larger prompts.
I'm especially interested in feedback from developers building with LLM APIs:
**How do you currently monitor token usage and API costs in your projects?**
And what would you add to a token calculator to make it genuinely useful in a real development workflow?
