A second brain for your prompts

Last updated: 20 June 2026

Prompt Doctor diagnoses the thinking flaws behind weak prompts, rewrites them at a higher level, and coaches you to reason like a strategist.

Diagnose flaws

Find missing context, vague verbs, weak constraints and untested assumptions in any prompt.

Rewrite higher

Get a tightened, structured prompt with roles, constraints, output format and success criteria.

Learn the thinking

Each analysis ends with a short lesson so you internalise the pattern, not just the result.

Reason like a strategist

Move from search-engine queries to structured briefs that frame the problem clearly.

Works across models

Use rewrites with ChatGPT, Claude, Gemini, Grok, Deepseek and other LLMs.

One-click improvements

Apply suggested fixes instantly, no copy-pasting tweaks back and forth.

Save what works

Keep a personal library of high-performing prompts you can reuse and refine.

Coaching, not autocomplete

Feedback is opinionated and concrete, designed to make you better, not just your prompt.
