Toolzoid Prompt Builder vs Typing Prompts Manually

What makes a good ChatGPT prompt?

A good prompt includes a Role (who the AI should be), Context (background situation), Task (exactly what you want), Format (output structure), and Examples (what good looks like). This RCTFE structure consistently produces better results.

How do I get better results from Claude or Gemini?

Specify a role, provide context about your audience and situation, give explicit format instructions (length, structure, tone), and include one example of the output style you want.
