About This Tool
This application uses Anthropic's official token counting API for accurate token estimates.
A tokenizer breaks text into smaller units (tokens) that language models process. Accurate token counting is crucial.
Here's how this tool helps:

- ✅ Predictable API Costs
- ✅ Stay Within Rate Limits
- ✅ Optimize Prompts
- ✅ Save Money
