Token Counter
AI models don't count words — they count tokens, and their memory (the context window) is a fixed number of them. Paste anything below to see how big it really is to an AI, and how much of each model's memory it would use.

That's about 0 pages of text.
How much of a context window is that?
The context window is the model's working memory — everything it can “see” at once.
Small / older free models · 8k tokens

Mid-size models · 32k tokens

Flagship models (Claude / GPT class) · 200k tokens

Long-context models (Gemini class) · 1M tokens

Estimates only — every model splits text into tokens slightly differently (≈4 characters or ¾ of a word each in English). Why this matters: What Is AI, Actually?
