Token Counter Showdown
Chop your own sentence into tokens, the tiny word parts AI reads.

How AI Actually Reads You
AI does not read the way you do. It does not see words. It sees tokens, which are bite-size chunks of words. Sometimes a whole word is one token. Sometimes a long word gets chopped in half.
- cat is usually 1 token
- unhappiness might be 3 tokens: un + happy + ness
- a space counts too
- emojis often eat 2 or 3 tokens each

Token counter
Try this sentence. See how it gets chopped into tokens.
How the AI sees it:
14 tokens · 44 characters
Rule of thumb: about 4 characters per English token. AI models charge and think in tokens — not words.

Key terms in this lesson
The big idea: your words become little Lego chunks called tokens before the AI ever thinks about them. Smaller piles, faster answers.

Computers only understand numbers. So how do they read your messages? They turn every word into a secret number code. So when you type a message to an AI, something sneaky happens.
