PromptCoach

About

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.
