Write better AI prompts. Local-first prompt analysis and coaching for ChatGPT, Claude, and more. PromptCoach is the in-browser coach that helps you write better prompts for every AI tool you use — ChatGPT, Claude, Gemini, Perplexity, and beyond. It reads what you're typing, scores it across the things that actually matter (clarity, context, constraints, role, examples, output format), and offers one-click rewrites that make any model do its best work. — WHY PROMPTCOACH — • Coach your prompts BEFORE you hit send. No more chat threads wasted on clarifying questions. • Works everywhere. Native integrations for chatgpt.com, claude.ai, and a panel that follows you around the web. • Local-first by default. Your prompts are analyzed in your browser. We never see them unless you opt in to cloud features. • Built for power users. Keyboard-driven. No bloat. No nags. — WHAT YOU GET — ✓ Real-time prompt scoring across 6 dimensions ✓ One-click rewrites in your tone ✓ Reusable prompt templates and snippets ✓ Side-by-side comparison of before/after ✓ Library of coach-curated patterns (chain-of-thought, role-play, few-shot, output schemas, and more) ✓ Multi-language support ✓ Dark mode — PRIVACY — PromptCoach runs in your browser. By default, every analysis is done locally and nothing leaves your machine. Optional cloud features (e.g. stronger rewrites via a hosted model) are off by default, clearly marked, and rate-limited so you stay in control. — WHO IT'S FOR — → Engineers who use AI in their daily flow and want repeatable results → Writers, marketers, and researchers who live inside LLM chat tools → Anyone tired of "good enough" answers from "good enough" prompts — PERMISSIONS, EXPLAINED — • storage: save your settings and templates • tabs: detect which AI tool you're using • host permissions (chatgpt.com, claude.ai): inject the coaching panel into the chat composer • alarms: schedule the daily quota refresh • offscreen: run the local analyzer without blocking the page PromptCoach does NOT collect your prompts, browsing history, or any personally identifying information. See our privacy policy for the full breakdown. — GET STARTED — 1. Install PromptCoach 2. Open ChatGPT, Claude, or any AI chat tool 3. Start typing — the coach panel appears as you write 4.
