💡 Prompt Writing Tips

✅Be specific — vague prompts produce vague answers.
✅Assign a role to the AI to anchor its perspective and expertise.
✅Specify the output format (list, JSON, table) to get structured results.
✅Use "Think step by step" for complex reasoning tasks.
✅Provide examples (few-shot) when you need a specific style or pattern.
✅Iterate — refine your prompt based on the model's output.
✅Keep image prompts under 400 tokens for best Midjourney/DALL·E results.

❓ Frequently Asked Questions

What is prompt engineering? ▼

Prompt engineering is the practice of crafting inputs to AI language models in a way that reliably produces high-quality, accurate, and useful outputs. It involves structuring your request with clear roles, context, constraints, and output format instructions so the model understands exactly what you need.

Does this tool send my prompts to a server? ▼

No. All formatting and analysis happens entirely in your browser using JavaScript. Your prompt text never leaves your device and is never transmitted to any server, stored in a database, or logged in any way.

What is a token and why does it matter? ▼

A token is roughly 3–4 characters or ¾ of a word. AI models have a context window limit measured in tokens — for example, GPT-4o supports up to 128,000 tokens. Keeping your prompt concise ensures you leave enough room in the context window for the model's response, and helps reduce API costs if you're using a paid API.

What is Chain of Thought prompting? ▼

Chain of Thought (CoT) prompting instructs the model to reason through a problem step by step before giving a final answer. Adding phrases like "Think step by step" or "Let's reason through this" significantly improves accuracy on math, logic, and multi-step reasoning tasks.

What is Few-Shot prompting? ▼

Few-shot prompting means providing the model with 2–5 examples of the input/output pattern you want before asking your actual question. This is especially effective when you need the model to follow a very specific format, style, or classification scheme that is hard to describe in words alone.
