AskSia Windows 版是什麼？
AskSia Windows 版是一款免費的原生 AI 學習智慧體。Sia 會陪你學習資料，並產生速查表、圖解和分步講解等互動式學習內容。備考時，她會規劃帶日期的路線，並提供貼近考試的模擬練習。
Windows 原生體驗
真正的 Windows 應用程式，不是偽裝成應用程式的瀏覽器分頁。
AskSia installs from a signed installer and behaves like a first-class Windows app.
Pinned to your taskbar
Open Sia like any Windows app — one click from the taskbar or Start menu, a full window with native minimize, maximize and close controls, ready the moment you sit down.
Native notifications
Windows notifications and the Action Center nudge you when a plan day unlocks or a mock is scored — so your prep keeps moving without you living in the app.
Fast on Windows 10 & 11
A native 64-bit build for Windows 10 and 11, code-signed so SmartScreen shows AskSia as the verified publisher. Review your plan and saved aids offline after first launch.
Sia 能做什麼
這是會主動產生內容的學習智慧體，不是需要你反覆驅動的聊天機器人。
放入 PDF、錄製課程，或直接提問。Sia 會陪你學習，並把內容變成可複習的材料。
Builds visual study aids
Cheat sheets, diagrams and step-by-step walkthroughs for any subject — from your materials or a single prompt, kept in a library you can remix.
Studies your materials with you
Snap a photo, record a lecture, or drop a PDF. Sia reads it, explains it, and answers with citations back to the source.
Plans & mocks any test
For any standardized test — SAT, ACT, GRE, GMAT, TOEFL, IELTS — Sia writes a dated plan and runs it: a diagnostic, drills from your misses, and exam-faithful mocks.

Prepping for any standardized test? Each part is its own tool.
Diagnose, Drill, Word Lab and Mock each have their own flow — and Sia sequences them into your plan, whether it's the SAT, ACT, GRE, GMAT, TOEFL or IELTS.
✦ Drill
Targeted Drill
Learn-first: Sia teaches the method in 3 moves, shows a worked example, names your recurring trap — then drills the items you missed plus fresh variants.
"From your misses — you picked C last time"
Live accuracy + streak tracking per skill
✦ Word Lab
Vocabulary
Spaced-repetition flip-cards for high-frequency words: pronunciation audio, an example sentence, and a handwritten memory hook from Sia.
Again / Hard / Good / Easy scheduling
Saves to your Word Book; Sia resurfaces them
✦ Mock
Full Mock Exam
A complete, timed mock full-screen in test-faithful chrome, scored on each exam's real scale — for the Digital SAT, with adaptive module routing and a timed break, side-chat locked like the real thing.
"Sia's read" names your biggest leaks + pacing
Queues targeted drills for each into tomorrow
Why a Windows app
A real workspace — full-screen focus a browser tab can't give you.
Real standardized tests are locked-down desktop apps. AskSia's mocks take over the full screen in test-faithful chrome (shown here: a Digital SAT mock), and your whole study lives in one window.
Full-screen, distraction-free. No browser tabs or notifications to break a timed run. Ask Sia locks during a mock.
Lives on your PC. Your plan, study aids, streaks and word book persist locally and are there to review offline.
Built for deep sessions. Split-pane passages, an on-screen calculator and audio — sized for a real screen, not a phone.

The author's central claim is that urban green space functions less as ornament than as infrastructure. Parks moderate temperature, absorb stormwater, and measurably improve residents' health — services that, the author argues, cities have historically undervalued because their benefits are diffuse rather than billed…
7⚑ Mark for ReviewA̶B̶C̶
Which choice best states the main idea of the passage?
AParks are primarily valued for their visual appeal.
BGreen space is essential infrastructure, not decoration.
CCities have always prioritized stormwater control.
DResidents' health is unrelated to urban design.

常見問題
下載前須知
Is the AskSia Windows app free?
Yes. The AskSia Windows app is free to download for Windows 10 and 11, with no credit card needed to start. The free plan includes studying your materials, building cheat sheets and diagrams, the test-prep planner, drills, vocabulary practice, and full mock exams. Optional Pro and Super plans add higher limits and advanced features, but the core study workflow is free.
Which PCs does it run on?
AskSia for Windows runs on Windows 10 and 11 (64-bit) and is a native Windows app. It pins to your taskbar, supports native Windows notifications, and the installer is code-signed so Windows SmartScreen shows AskSia as the verified publisher before it runs.
What can Sia do on the Windows app?
Sia studies your materials with you and builds interactive study aids — cheat sheets, diagrams and step-by-step walkthroughs — for any subject. For test prep she plans a dated roadmap, runs exam-faithful mocks, and drills the skills you miss. You can drop a PDF, record a lecture, or just ask, and she answers with citations.
Which tests can it mock?
The same diagnose-drill-mock workflow works for any standardized test — the SAT, ACT, GRE, GMAT, TOEFL and IELTS. The Digital SAT is the most fully built example today, with full-screen, exam-faithful mocks scored on the real 400–1600 scale, and more exams are being added.
Can it make cheat sheets, diagrams and quizzes for any subject?
Yes. Type a topic or drop your materials and Sia builds a dense single-page cheat sheet, a visual diagram or timeline, a step-by-step walkthrough, or a graded quiz — for any course or exam — and keeps them in a library you can remix.
Is it a native Windows app or a web wrapper?
It's a Windows app you install from a signed installer: it pins to your taskbar, posts native Windows notifications, supports full-screen distraction-free mocks, and keeps your plan and materials on your machine. After first launch you can review your plan and saved study aids offline, while building new aids and asking Sia need a connection.
Is my data private? Is it used to train AI?
Your study materials and progress are processed for your own queries and are never used to train AI models. Files you bring in stay private to your account, your plan and word book are kept on your machine, and you can delete your data at any time.
Is the download safe?
The Windows installer is code-signed, so Windows SmartScreen shows AskSia as the verified publisher before it runs. AskSia is used by more than 2 million students worldwide. You can uninstall it at any time from Settings, under Apps.
Is there a Mac version?
Yes. AskSia also has a native Mac app for macOS 12 or later, on Apple silicon and Intel, with the same study features — see the AskSia for Mac page.
