스승 · Seuseung

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
