FAQ

How is this different from the AI Token Calculator?

This tool gives a quick combined character/token view for fast iteration; the AI Token Calculator offers more precise, model-specific tokenization.

Is the estimate accurate?

Character-to-token ratio is a rough approximation (~4 characters per token for English); use the AI Token Calculator for exact OpenAI-style tokenization.
