Claude cuts you off mid-task. You were halfway through formatting a quarterly sales report, and now you've hit your daily limit. It comes back tomorrow. Your deadline doesn't.
That limit isn't measured in messages. It's measured in tokens — small chunks of text, each one roughly three-quarters of a word. Every prompt you type, every file you paste in, every reply Claude sends back gets counted against today's allowance.
Here's the catch: there's no visible counter while you work. You only find out you've run out when the wall shows up, usually in the middle of something that mattered.
A 10-page supplier contract, a full email thread, or the brief for a board presentation can each burn through thousands of tokens before you've asked a single question.
Rule: assume every upload and every reply counts against today's limit — because it does.
