WHO IS IT FOR? ────────────────────────────── • Developers and engineers using AI APIs and chat interfaces • Content creators working with long AI-generated documents • Researchers and students using Claude or Gemini for analysis • Anyone who has ever seen "context limit reached" and lost work • Power users who push AI assistants to their full capacity 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 ABOUT THE AUTHOR ────────────────────────────── Created by Joaquín Ruiz, Computer Engineer and AI Expert from Zaragoza, Spain. 📺 YouTube channel on Artificial Intelligence: youtube.com/@jokioki 📚 AI Books: jokiruiz.com/libros - El motor de la Inteligencia Artificial: https://amzn.eu/d/083CTN3U - Programar con Inteligencia Artificial: https://amzn.eu/d/eK4f73N - Explora la Inteligencia Artificial: https://amzn.eu/d/dSwYhue 🌐 Website: jokiruiz.com PRIVACY ────────────────────────────── AI Token COunter reads conversation text only to count tokens locally in your browser.
