AI Token Counter & Cost Estimator

Large Language Models (LLMs) are priced by tokens, not by words or characters—yet most users still estimate costs manually or rely on guesswork. A prompt that looks short can exceed context limits or generate unexpected API charges when scaled. This uncertainty makes budgeting AI projects difficult for developers, product teams, and businesses. The LLM Token Counter & API Cost Calculator solves this problem by instantly counting tokens and estimating API costs across major AI providers. This advanced llm token counter helps you understand context limits, control spending, and plan AI usage with confidence.

How to Use This AI Token Counter

Using the tool is fast and intuitive:

• Paste your prompt, response, or full conversation into the input field

• Select the AI provider and model (OpenAI, Anthropic, Google, etc.)

• Instantly view the token count for input and output

• See the estimated API cost based on current pricing

• Review context window usage and remaining tokens

• Adjust your prompt length to stay within limits or budget

• Copy results for documentation or cost tracking

No calculations required—the tool handles everything automatically.

Frequently Asked Questions (FAQ)

1. What is a token in LLM pricing?
A token is a chunk of text used by AI models to process language.

2. Are token counts the same across all models?
No. Different models tokenize text differently.

3. Does this tool use real pricing data?
Yes. It estimates costs based on current public pricing.

4. Is my prompt data stored?
No. All calculations run locally in your browser.
