Pronto is an AI-powered IDE for prompt engineering. Chat naturally, refine on a live canvas, grade your work, and publish to a community library.
Chat on the left, edit on the right. Real-time prompt building.
Automated scoring on structure, clarity, and best practices.
Publish, share, and monetize your best prompts.
Master these fundamentals and your first prompt will score 85+.
Start with 'You are a [role] with [years] of experience in [domain].' This anchors the model's behavior.
Use XML tags like <instructions> and <context> to prevent the model from confusing what to do with what to know.
Include 2-3 input/output examples. Few-shot examples beat long descriptions every time.
Specify format (JSON, markdown, bullet list), length ('respond in under 200 words'), and tone explicitly.
'Do NOT include greetings, disclaimers, or filler text.' Telling the model what to avoid is as important as what to include.
Add 'Think step by step before answering.' This dramatically improves accuracy on reasoning tasks.
Tell the model what to do when input is missing, ambiguous, or invalid. 'If the user provides no budget, assume $500.'
Small changes can cause big regressions. Pronto's snapshot system tracks every edit so you can always revert.
Try empty strings, very long inputs, off-topic requests. A production prompt should handle all of them gracefully.
Don't guess what's missing. The 12-dimension score tells you exactly which areas need improvement.
