Working with LLMs
The AI Prompt Generator turns a task into a structured prompt — role, context, constraints and output format — from templates for techniques such as chain-of-thought and few-shot prompting. The Prompt Formatter cleans and inspects a prompt you already have.
The LLM Token Counter estimates how many tokens a text uses, which is what model context limits and API pricing are measured in. A token is roughly four characters of English text, so a 2,000-word document is around 2,700 tokens.
Learn the techniques
The AI Prompt Engineering hub explains each technique with examples: when to use chain-of-thought, how many examples few-shot prompting needs, and how to ask for structured JSON output a program can parse.
