I built a free English-interview trainer for Koreans — answers come with Korean pronunciation under every sentence

Korean job seekers often know English but freeze in interviews: the answer exists in your head, your mouth won't start.

So I built Interview Copilot. The flow:

• An AI interviewer asks questions by voice (TTS)
• An answer is generated from YOUR resume (not generic templates)
• Every English sentence gets Korean pronunciation right under it — "As a solo builder" → "애즈 어 솔로 빌더"
• Answer timer + 10-second countdown + coach feedback in Korean when you finish

If the answer doesn't come to you, you just read it out loud. After a few rounds it sticks.

Privacy design I care about: it's BYO-key. You paste your own Claude/OpenAI API key and the browser calls the LLM directly — your resume and the whole conversation never touch my server. The key lives in localStorage only.

Honest downsides: getting an API key is a 5-minute chore if you've never done it, and the free-tier host is slow on cold start.
