🔢 AI Token Counter
Estimate token count and API cost for any AI model before making your call.
About AI Token Counter
Before you send a large request to an AI API like OpenAI or Anthropic, it's smart to know how many tokens it uses. Tokens directly affect both your speed and cost — most models charge per token, and each model has a hard cap on how many you can send in one request. This tool gives you an instant token estimate so you can optimize before making the call.
Just paste your prompt or text, select your target model, and get a token count and estimated API cost breakdown immediately. Handy for testing small prompts and for estimating the cost of processing large documents or long conversation histories. No API key required — the estimation runs entirely in your browser.
