Free prompt optimizer
Improve an AI prompt without changing what you meant
Use Promptify as a prompt optimizer: clarify the task, fill missing context, add useful constraints, and preserve your intent before you paste it into an AI model.
Add your details, then open the full builder to shape a structured brief.
No signup required. Review the brief before using it.
Build my briefA prompt optimizer should preserve your intent while making the task, context, constraints, and expected output easier for an AI model to follow.
What changes
A useful brief makes the missing decisions visible.
- Preserves original intent
- Separates missing facts from assumptions
- Adds a checkable answer format
Example output
Optimized prompt
Task: create a practical 30-day launch plan for my app. Before making recommendations, ask only the questions that would materially change the plan. If information is missing, state the assumption instead of inventing a fact. Return: 1. the highest-leverage launch activities in order 2. a week-by-week plan 3. the audience, channel, budget, and effort assumed for each activity 4. one low-cost validation step 5. risks and signals that would cause the plan to change Keep the plan specific to an early-stage product and avoid generic advice.
Practical guide
What makes this brief useful
Prompt optimization should reduce ambiguity, not add impressive-sounding filler. The strongest changes make the task easier to execute and the result easier to evaluate while leaving the user's actual goal intact.
Good fit for
- Improving an existing ChatGPT or Claude request
- Making research prompts more evidence-based
- Tightening coding, writing, or analysis instructions
Before you run it
- Keep the original outcome visible.
- Do not invent missing context.
- Convert vague preferences into observable requirements.
- Ask for uncertainty and next steps when the task is open-ended.
