複製貼上會切斷思路Copy and paste breaks your train of thought
開另一個 AI、貼上內容、補充背景，再回頭找剛才讀到哪裡——真正想理解的事，反而被操作步驟淹沒。Opening another AI, pasting context, and finding your place again adds friction exactly when you are trying to understand.

看不懂，
不必離開原本的工作。When it does not make sense,
stay in your flow.
在 Mac 選取文字，或從 iPhone 分享文字與截圖，立刻得到核心答案、白話拆解與例子，並自動收進只存在裝置上的理解帳本。Select text on Mac, or share text and screenshots from iPhone, to get a core answer, a plain-language breakdown, and an example—saved only to your device.

這什麼意思？
你選取了You selected404 Not Found
核心答案Core answer
這個網址指向的頁面找不到。它可能不存在、已搬走，或網址打錯了。The page at this address cannot be found. It may not exist, may have moved, or the address may contain a typo.
就像照地址找店，到了卻看不到店面。It is like following an address but finding no shop there.
先檢查網址，再試著回上一頁或回首頁。Check the address, then try going back or returning to the home page.
為什麼需要它Why it matters
你不是不會問，
只是不該為了追問而被打斷。You know how to ask.
Asking should not break your flow.
「這什麼意思？」只在你主動選取或分享時工作，讓解釋成為原本流程的一部分。What Does This Mean? works only when you select or share something, making explanation part of the flow you already have.
問題散落在長對話裡Questions disappear into long chats
學習、工作與除錯問題混在一起。過幾天想回頭找，通常只記得「我好像問過」。Learning, work, and debugging questions get mixed together. Days later, you only remember that you asked something.
便利不該交換隱私Convenience should not cost privacy
少按幾次，不代表 App 就該監控剪貼簿、讀取整個照片圖庫，或代替官方客戶端保存登入憑證。Fewer taps should not require clipboard monitoring, full photo-library access, or copied sign-in credentials.
實際功能Product features
一次叫出，照你的理解習慣回答。Invoke it once. Get an answer shaped around how you understand.
三層答案Three-layer answers
紅色抓核心、黃色做白話拆解、藍色補例子。顏色負責導航，正文維持高對比黑底白字。Red highlights the core, yellow explains it plainly, and blue adds an example. Color guides; high-contrast text explains.
說出卡點Name the blocker
第一次看到、名詞太專業、邏輯跳太快、和前文接不上，或想看一個例子。Say whether it is new, too technical, too fast, disconnected from context, or simply needs an example.
同題持續追問Keep asking in context
原因按鈕、自訂追問與建議問題都留在同一個 session，不會每問一次就散落一張卡片。Reason buttons, custom follow-ups, and suggested questions stay in one traceable session.
本機理解帳本A local understanding ledger
依主題與時間保存；卡片預設收合，點擊後展開完整問題、回答與每輪時間。Save by topic and time. Cards stay collapsed until you choose to review the full exchange.
依情境選 AIChoose AI by context
Apple 裝置端模型零設定優先；也能使用 Mac 官方訂閱客戶端，或在 iPhone 自願設定官方 API。Apple on-device intelligence is the zero-setup default, with optional official clients or APIs when you choose.
截圖理解 BetaScreenshot understanding beta
截圖先在 iPhone 做 OCR 與影像特徵辨識。證據不足時停止推測，不硬湊答案。iPhone runs OCR and visual checks first. If evidence is weak, the app stops instead of inventing an answer.
操作流程How it works
少一步，
就更接近不中斷。One less step.
One less interruption.
正常流程不要求再次按送出、挑模型，或反覆登入。The normal flow does not ask you to submit again, choose a model, or repeatedly sign in.

展示案例Interactive example
先試著理解一個常見問題。Try understanding one common problem.
這是本機互動示意。按鈕只切換頁面內容，不會把文字送出瀏覽器。This demo is local. Its buttons only change the page and never send text out of your browser.
你選取了You selected404 Not Found
可能想問的原因What might be blocking you
核心答案Core answer
這個網址指向的頁面找不到。頁面可能不存在、已搬走，或網址打錯了。The page at this address cannot be found. It may not exist, may have moved, or the address may contain a typo.
白話拆解Plain-language breakdown
就像照著地址去找一間店，到了卻找不到店面：它可能搬走、關門，或地址寫錯。It is like following an address but finding no shop there: it may have moved, closed, or the address may be wrong.
依你的卡點補充Based on your blocker
404 是網站的回覆，表示它找不到這個網址對應的頁面。404 is the website's reply saying it cannot find a page for this address.
圖片理解 BetaImage understanding beta
能讀截圖，也知道什麼時候不該猜。Read screenshots—and know when not to guess.
iPhone 會先在裝置端辨識圖片中的文字與少量影像特徵。原始圖片不交給文字模型，也不寫入理解帳本。iPhone first identifies text and limited visual signals on-device. The original image never goes to the language model or the ledger.
發布前品質閘門Pre-release quality gates
- 狀態列與純數字不能被當成正文Status bars and isolated numbers cannot become the main text
- 資訊不足時不呼叫模型、不保存假答案Weak evidence means no model call and no fabricated answer
- 人物、作品與事件必須能追溯到圖片證據People, works, and events must trace back to image evidence
- 正常圖片仍維持分享後自動回答Valid images still receive an automatic answer after sharing
目前狀態：社群、影片與聊天截圖仍在發布前驗收；正式版會在證據不足時明確停止，不產生沒有來源的具體故事。Current status: social, video, and chat screenshots are still in pre-release validation. The release build will stop when evidence is insufficient rather than inventing a story.
使用場景Use cases
在卡住的那一刻，直接接住你。Meet the moment you get stuck.
Terminal 除錯Terminal debugging

論文與課程Papers and courses
替第一次出現的概念補上定義、因果與具體例子。Add definitions, causes, and concrete examples to a new concept.
社群與新聞截圖Social and news screenshots
從圖片證據開始；資訊不足時保留 OCR，不自行補故事。Start from image evidence; retain OCR and stop when the evidence is insufficient.
跨語言閱讀Cross-language reading
保留原文重點，再用你熟悉的語言拆解意思。Keep the source meaning, then explain it in a language you know.
安全與隱私Security and privacy
低摩擦，
不代表降低安全標準。Low friction
does not lower the security bar.
App 採 local-first 設計；供應商、裝置端與本機帳本之間都有明確邊界。The app is local-first, with explicit boundaries between providers, on-device processing, and the local ledger.
01只處理你當次主動選取的文字或分享的單張圖片Process only the text or single image you actively select or share
02不監控剪貼簿、Terminal history、螢幕或照片圖庫Never monitor the clipboard, Terminal history, screen, or Photo Library
03常見 API Key、token、密碼與個資先在本機遮罩Mask common API keys, tokens, passwords, and personal data locally first
