Token counts are estimates. Actual token counts depend on the model's tokenizer.
How to Use
Paste or type your text into the input area. The tool instantly counts characters, words, lines, and estimated tokens, then displays API cost estimates for 16 popular AI models including:
Anthropic: Claude Opus 4.6, Claude Sonnet 4.6/4.5/3.5, Claude Haiku 4.5
Google: Gemini 3.1 Pro, Gemini 3 Flash, Gemini 2.5 Pro
Others: DeepSeek V3
The table shows each model's standard rate (per 1M tokens) alongside the actual cost calculated from your input text. Use this tool to estimate costs before making API calls and choose the best model for your needs.
