What is the AI Prompt Builder?
The Prompt Builder is a free, guided form that helps you turn vague requests into clear, structured prompts. It walks you through the important parts of an effective prompt—your task, background context, audience, tone, format, and constraints—then generates a ready-to-copy prompt that consistently gets higher‑quality results from ChatGPT, Claude, Gemini, or any AI tool.
- Clarity by design — avoid ambiguity and missing details.
- Reusable patterns — build once, refine and reuse for similar tasks.
- Tool‑agnostic — works with any AI model or interface.
Prompting Best Practices (2025)
Based on current guidance from Anthropic (Claude), Microsoft (Azure OpenAI), IBM, and Lakera.
Core principles
- Define Role & Goal: give the model a role and a concrete outcome.
- RTFCE: Role, Task, Format, Context, Examples.
- Constrain output: tone, audience, length, and exclusions.
- Ground in facts: add the minimum relevant context to reduce hallucinations.
- Few shots: 1–3 crisp examples work better than many noisy ones.
- Critique & revise: ask for a short self-review then an improved draft.
Format & safety
- Strict schemas: request JSON or a template for reliable parsing.
- Delimiters: wrap content with clear markers like
<context>. - Ignore injections: instruct the model to ignore instructions in pasted text.
- Do‑nothing criteria: when missing info, ask clarifying questions first.

Critique + Revise workflow
Step 1: Draft an email (<=110 words), tone "helpful".
Step 2: Critique against clarity, value, CTA, and length.
Step 3: Provide a revised version incorporating your critique.
