Physiatrist (PM&R) in Hualien, Taiwan — rebuilding medicine, learning, and life with evidence + engineering.
花蓮的復健科醫師，會寫程式。用實證＋工程重構醫學、學習與生活；下面每個工具都是我每天真的在用、整理後才開源的。
I'm a rehabilitation physician who codes. My favorite problems live at the intersection of clinical medicine × evidence-based practice × AI knowledge workflows × self-hosting — and I write up how each tool is built, in public.
- 🏥 By day — physiatrist at Hualien Tzu Chi Hospital: musculoskeletal ultrasound, manual therapy, sports medicine
- 🔬 By training — evidence-based medicine: meta-analysis, critical appraisal, national health-insurance database research
- 🤖 By night — building AI-powered study & research pipelines with Claude Code, Obsidian, and a homelab
Everything here is exhaust from my real daily workflow — I build tools to use them, then open-source what survives.
| Project | What it does |
|---|---|
| 📡 paper-radar | Personal literature radar — journal/PubMed feeds → interest-scored triage site → straight into your notes. Discovery end of my paper pipeline. |
| ⬇️ paper-fetch | Publisher-aware full-text fetcher — DOI in, PDF out, via open access → publisher TDM APIs → your own institutional proxy. Download end of the pipeline. |
| 📖 paper-review-and-digest | Claude Code skills for journal-club-grade paper appraisal (deterministic GRADE + CrossRef gate) and fast content digest. Reading end of the pipeline. |
| 📚 textbook-to-note | Turn your own PDF textbooks into an AI-searchable knowledge base and structured, fully-cited notes — figures included. Local-first, token-frugal. The tool that carried me through board exam prep. |
| 🎬 lecture-to-notes | Lecture recordings → grounded notes + a synced HTML viewer: video, timestamped transcript and curated summary on one page, kept in sync both ways. Takes any mix of video, audio, PDF deck and slide photos onto one timeline. Local GPU pipeline, zero API cost until the final write. |
| 🎙️ asr-benchmark | Score speech-recognition models on your own audio with no ground-truth transcript — build a lexicon from your field's literature, then measure real terms captured vs hallucinated. |
| 🔍 ask-your-library | Ask your own library — textbooks, guidelines, lecture notes and your notes — and get answers that cite the page. Local-first search hub: MCP server for Claude Code + Obsidian plugin. |
| 📝 exam-practice | Self-hostable past-exam practice platform driven by FSRS spaced repetition, built for medical board prep. |
| 🧩 note-supplement | Merge new source material into the notes you already have — conflict detection, tier-gated writes, mandatory citations. Pairs with textbook-to-note (writes new notes) and ask-your-library (finds the targets). |
| 🩺 openevidence-tools | MCP server for OpenEvidence + an /oe-verify skill that cross-checks every citation before you trust the answer. |
| ⏱️ claude-pacer | Statusline + budget guard + pacing verdict for Claude Code usage limits — the statusline is for you, the guard is for Claude, the verdict is for your agents. |
| Project | What it does |
|---|---|
| 🧽 chart-scrub | Rule-based de-identification for Traditional Chinese (Taiwan) clinical text. Runs locally, no dependencies — try it in the browser. |
| 🌐 deja-browser | The agent browser that remembers: its own Chromium profile, and site recipes that skip the re-read. |
| 讓 AI 先訪談你、建立你自己的旅行總檔，再陪你走過每趟旅行的前中後。 | |
| ⚡ ha-taipower-estimate | 台電電費估算：Home Assistant 整合（HACS 一鍵安裝）＋ YAML package。 |
| 📈 loan-invest-sim | Is it worth borrowing at 2% to buy global ETFs? Reproducible Monte Carlo study + browser simulator. |

I write (mostly in Traditional Chinese) about rehab medicine, AI knowledge workflows, and self-hosting at drpwchen.com — how each tool above was built, what broke along the way, and what I'd do differently.
🧰 Full inventory: everything I actually use — AI assistants, ASR/OCR engines, free hosting, homelab, backup — is catalogued by purpose in my AI toolbox.
If any of these tools saved you some time, you can buy me a boba 🧋 — it keeps the homelab humming.
This tool is one piece of my personal AI workflow. If you want to learn how to use AI agents like Claude Code from zero (no programming background needed), I wrote a beginner series (in Traditional Chinese):
這個工具是我個人 AI 工作流的一部分。想從零開始學怎麼用 Claude Code 這類 AI agent（不需要程式背景），可以從我的入門系列開始：
