Estimate uses both the character/4 rule and the word/0.75 rule, averaged. For exact counts, use a real tokenizer (tiktoken for OpenAI, Anthropic's count-tokens API for Claude). This estimate is usually within 5-10% for English text and gets less accurate for code, JSON, or non-Latin languages.

About

Paste any text. Get an estimated token count using both the character/4 and word/0.75 heuristics, plus the cost as input tokens across major LLM providers. For exact counts use the provider's tokenizer.

How to use

  1. Paste text.
  2. Read estimated token count.

FAQ

How accurate is this?+

Within 5-10% for English text. Less accurate for code (more tokens per char), JSON (variable), non-Latin scripts (sometimes 2-3x more). For exact counts, use the official tokenizer.
