About this app
PeMaster AI helps prepare for Korea's Professional Engineer (기술사) exam with Korean reading, listening and recall practice.
STUDY RIGHT AFTER INSTALLING
- Examples make all study tabs ready after installation. Four editable sample files are saved in Download/PEMaster.
PAST AND PREDICTED QUESTIONS (study_bank.json)
- Search by round, period and domain; read model answers, write drafts, keep review records and filter difficult questions.
- Predictions are practice items with sources and related past questions. Send search results to listening, flashcard or interview practice.
LISTEN AND READ: TTS MEMO NOTES
- Filter by round/period; hear recent exams first or shuffle. Reshuffle when wanted. Add, remove and reorder a listening list saved separately from favorites and bookmarks.
- Play each item once or loop the list. Individual 1/3/5/endless repeats, 0.8–1.8x speed, 5/10/20-minute commute practice and background controls are also available.
FLASHCARDS
- Recall definitions and keywords, flip to compare, then review with spaced repetition.
AI MOCK INTERVIEW (oral exam)
- Live answers become text for keywords, timing and eye contact. Dropped speech connections retry without duplicates.
- [Larger view] frames your seated body in preview.
- You can choose to record video and audio on this device. Live speech recognition cannot run while recording; supported Android 13+ devices try on-device transcription afterward, with manual answer entry available.
- Completed questions, original answers, scores and coaching save locally. In [Saved interviews], play and seek recorded video, add improvement notes and re-evaluate revised answers.
- Default mode does not store camera video or raw audio; Android speech recognition may process audio remotely. Keeping recorded media is optional, off by default, local-only and never uploaded.
- An optional on-device model adds advisory feedback; messenger traffic passes through that service.
YOUR OWN MATERIALS: GOOGLE DRIVE OR DEVICE FOLDER
- Read My Drive/PEMaster (created with samples if missing), or choose device files without Google. Verified copies work offline.
SOLVE FROM VS CODE ON YOUR PC (MCP)
- Enable MCP in Settings. VS Code or Claude Code can access questions, cards, notes and interviews, with feedback and self-grades recorded in the app. Connect over USB, Wi-Fi, VPN or your own ngrok tunnel. The phone is the server.
SLACK: WRITE ON A PC, REVIEW ON YOUR PHONE
- Write and edit long answers on a larger screen; submissions save as phone drafts and self-grades update the same review schedule.
- In a PE Master direct message, send "문제 기출 2교시" and submit with "submit " or "답안 ". Rate 1 hard (10 min) through 5 mastered (7+ days) to open the next question.
- [Next question]/next keeps the draft without grading; [Help] preserves study state and [Home] keeps saved work. Bookmarks, AI feedback, cards, interviews and notes also work from Slack.
- Mobile data, @PE Master and /pemaster work without shared Wi-Fi. Keep the phone online and the bot running; battery restrictions can interrupt it.
PRIVACY AND PERMISSIONS
- Records stay on the phone; no developer server is involved. Completed interview questions, original answers, scores and coaching save in app-private storage. Slack messages and feedback may be retained or accessed under workspace policies. Users of one bot share the same phone study records; a personal bot and direct messages are recommended.
- Tokens are encrypted on the device. Drive reads study files and writes only app-created files. Camera and microphone are used for mock interviews. Default live mode does not store video or raw audio; optional recorded media is local-only, off by default, and never uploaded. Android speech recognition may process audio remotely. No location is collected.
Past questions are based on public Q-Net material; model answers and predictions are unofficial study aids, not an official marking scheme. A banner ad is shown at the bottom of the screen.
