Reskin Claude, ChatGPT, and Gemini into an enchanted handwritten diary — you write in ink, the page replies. 把 Claude、ChatGPT、Gemini 三大 AI 偽裝成一本會回話的手寫魔法日記 —— 你落筆，紙頁回字。
Local-only · No tracking · Fully open source ｜ 純本機 · 不追蹤 · 完全開源
A Chrome extension that overlays a parchment "magic diary" on top of Claude, ChatGPT, and Gemini. You write on the page, it relays your words to your already‑logged‑in AI, and the reply surfaces as ink — letter by letter, like an enchanted grimoire writing back. One experience, three AI platforms.
一個在 Claude、ChatGPT、Gemini 三大 AI 對話平台上蓋一層羊皮紙「魔法日記」的 Chrome 擴充。你在紙頁上寫字，它把內容轉交給你已登入的 AI，回應再以墨水浮現 —— 字字滲入紙面，宛如一本會回話的魔法古籍。一個擴充，三大平台，同款沉浸體驗。
| 平台 | 網域 | 狀態 |
|---|---|---|
| Claude | claude.ai | 支援（selectors 已驗證） |
| ChatGPT | chatgpt.com、chat.openai.com | 支援（selectors 待 live 驗證，見 T4-E） |
| Gemini | gemini.google.com | 支援（selectors 待 live 驗證，見 T4-E） |
This project is built to be verifiable, not just "trust me." Both Taiwanese and international users should be able to confirm it is safe.
- No servers of ours. The extension talks to nothing we operate. There is no backend, no analytics, no telemetry, no data collection.
- No network calls in the code.
content.js(~1000 lines — runwc -l content.jsfor the current figure) contains zerofetch,XMLHttpRequest,WebSocket, orsendBeacon. Verify it yourself:grep -nE "fetch\(|XMLHttpRequest|WebSocket|sendBeacon" content.js # → nothing
- Your conversation data never leaves your browser. The extension reads/writes the page DOM in your tab (on Claude, ChatGPT, or Gemini). It never touches your password, session cookies, or any API key, and never copies your conversations anywhere.
- Zero external requests — not even fonts. Both typefaces — Tangerine (English) and Chenyuluoyan (Chinese) — are bundled locally in
fonts/and loaded overchrome-extension://. The extension contacts no outside host whatsoever. - Minimal permissions (see table below) — no
tabs, no<all_urls>, no remote code execution. - Open source, MIT-licensed. Every line is in this repo. Fonts ship with their original OSS licenses in
licenses/. - Codebase is in Traditional Chinese (zh‑Hant). UI strings, comments, and docs use 繁體中文.

So the page can load the locally bundled Traditional Chinese font over chrome-extension://. |

That is the complete list. There is no tabs, cookies, webRequest, <all_urls>, or background service worker.

chrome://extensions - Turn on Developer mode (top right)
- Click Load unpacked and select this
riddle-diaryfolder - Go to
https://claude.ai,https://chatgpt.com, orhttps://gemini.google.com, open a conversation — the diary appears
- Open the book — tap the closed cover to flip it open.
- Write — type at the bottom of the page;
Enterto send,Shift+Enterfor a new line. (IME composition is respected — your first Enter just confirms candidates.) - Bookmark / history — click the red ribbon on the left edge to slide out your past conversations; click one to switch, or "✚ open a new page" to start fresh.
- Peek — press and hold "窺視" (top‑right) to briefly see the real AI interface underneath.
- Close — "闔上" (top‑right) removes the disguise; a small floating book button appears at the bottom‑right to reopen it directly (or use the toolbar icon).
- A content script overlays a full‑screen parchment book on Claude, ChatGPT, or Gemini — whichever tab you have open.
- On send, it writes your text into the AI's real input box and clicks send.
- It polls for the latest assistant message, cleans it (drops accessibility labels / buttons / thinking blocks), and renders the reply as ink once the AI finishes.
Each platform has its own selector configuration file: platforms/claude.js, platforms/chatgpt.js, platforms/gemini.js. When a platform changes its markup, you usually only need to update that platform's selectors object.

這個專案的設計原則是「可以自己驗證，而不是叫你相信我」。台灣使用者與外國使用者都應該能自行確認它是安全的。
- 沒有我們的伺服器。 擴充不會跟任何我們經營的服務通訊。沒有後端、沒有分析、沒有遙測、不蒐集任何資料。
- 程式碼裡沒有任何對外連線。
content.js（約 1000 行——實際行數以wc -l content.js為準）裡 完全沒有fetch、XMLHttpRequest、WebSocket、sendBeacon。你可以自己驗：grep -nE "fetch\(|XMLHttpRequest|WebSocket|sendBeacon" content.js # → 什麼都沒有
- 你的對話資料不會離開瀏覽器。 擴充只在你的分頁裡讀寫 AI 平台（Claude、ChatGPT、Gemini）的頁面 DOM，從不碰你的密碼、session cookie 或任何 API key，也不會把你的對話複製到任何地方。
- 零對外請求 —— 連字型都不連網。 兩款字型 Tangerine（英文）與辰宇落雁體（中文）都打包在本地
fonts/，以chrome-extension://載入。擴充不向任何外部主機發出請求。 - 最小權限（見下表）—— 沒有
tabs、沒有<all_urls>、不執行任何遠端程式碼。 - 開源、採 MIT 授權。 每一行都在這個 repo 裡。字型也附上原始開源授權於
licenses/。 - 程式碼以繁體中文（zh‑Hant）撰寫。 介面字串、註解、文件都用繁體中文。
