AI assistants like Claude, ChatGPT and Gemini can save hours, but results depend on how you use them. Good prompts, the right tool and an eye on costs make the difference.
What's changing: AI is moving from chat answers to agents that complete multi-step tasks, and new tools launch every week, so knowing what to use and how to prompt it is a valuable skill.
Frequently asked questions
How accurate is it?
About ±10–20% for English. Each model uses its own tokenizer, so use your provider's token counter for exact numbers.
Why do Arabic and other scripts use more tokens?
Tokenizers are often trained mostly on English, so non-Latin text splits into more pieces.
