PromptCoach

Write better AI prompts. Local-first prompt analysis and coaching for ChatGPT, Claude, and more.

Other tools rewrite your prompt. PromptCoach teaches you how to improve it. Open PromptCoach while writing in most of the well-known AI platforms. It evaluates five dimensions: goal clarity, context, response format, constraints, and examples. Goal clarity is always scored. When an optional dimension would not improve the current task, PromptCoach marks it “Not needed” instead of encouraging extra prompt length. Use the coaching panel to understand the score, review focused suggestions, create and apply an improved draft, and revisit recent checks in history. Scores are practical guidance for the task, not guarantees of response quality. Local mode analyzes prompts in the browser. Signed-in users may opt into cloud scoring and receive up to 10 cloud prompt checks per day; the allowance resets the following day. A free PromptCoach account also keeps cloud history, Academy training, progress, and synchronization together. No credit card is required. PromptCoach is for learners, students, educators, writers, researchers, marketers, and developers who want to understand prompt-writing decisions rather than blindly accept a rewrite.
