  description

  스승 (Seuseung) is the Korean word for a revered life mentor — deeper than teacher, closer to master. That's what this extension is.
  
  Unlike every other prompt tool, 스승 doesn't just rewrite your prompt. It teaches you WHY the improved version works — so you get better over time.
  
  ─── WHERE IT LIVES ───────────────────────────────────
  스승 is injected directly inside Claude, ChatGPT, and Gemini.
  No copy-paste. No switching tabs. Just type your prompt,
  click the floating 🎓 button, and the lesson slides in.
  
  ─── WHAT YOU GET ─────────────────────────────────────
  ✦ Prompt score — Clarity, Context, Specificity (1–10)
  ✦ Diagnosis — exactly what's weak about your prompt
  ✦ Improved version — optimized for your chosen AI
  ✦ 스승의 가르침 (The Master's Teaching) — named explanations of each change with the cognitive reason it works better
  ✦ Transferable principles — 3 lessons you can apply to every future prompt
  
  ─── PER-AI OPTIMIZATION ──────────────────────────────
  Claude  →  XML structure tags: <context><task><format>
  ChatGPT →  Persona framing + numbered step-by-step
  Gemini  →  Clean section headers + structured format
  
  ─── MULTILINGUAL ─────────────────────────────────────
  Type in Korean, Spanish, Arabic, Japanese, Chinese, or English. 스승 detects your language and responds in kind.
  
  ─── FREE & PRO ────────────────────────────────────────
  Free:  10 lessons per day · full features
  Pro:   Unlimited · $4/month or $29/year
