This tool gives you universal token analysis across major LLM providers. OpenAI counts run locally, Gemini counts can be verified with Google's countTokens API, and Claude exact counts are available when Anthropic credentials are configured.

The comparison table still updates instantly for every model so prompt sizing and cost planning stay fast while provider-backed exact counts load for the selected model.

Why token count matters

Token count controls prompt cost, response headroom, and whether a request fits inside the model's context window.

Universal token analysis

Use one tool to inspect current OpenAI, Claude, and Gemini families instead of maintaining separate token calculators for each provider.

Prompt optimization

Dense code, JSON, XML, and multilingual text usually consume more tokens than plain English prose. Trim boilerplate first.

Frequently Asked Questions

Everything you need to know about using this tool effectively and securely.

Q.É exato para o OpenAI?

É uma aproximação muito próxima (regra prática: ~4 caracteres por token). Para precisão de byte exata, a tokenização oficial pode variar ligeiramente.
