WHY DOES TOKEN COUNT MATTER?
──────────────────────────────
Every AI model has a context window — the maximum number of tokens (words + punctuation) it can process in a single conversation. When you exceed that limit, the model starts forgetting the beginning of the conversation, leading to inconsistent or incorrect responses.

Knowing how many tokens you've used helps you:
→ Avoid unexpected context resets mid-task
→ Plan long multi-step workflows with AI
→ Understand when to start a new conversation
→ Get more predictable, accurate AI responses
