✦ Quick answer
What is the AskSia Mac app?
AskSia for Mac is a free, native AI study agent for macOS. 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 and runs exam-faithful, full-screen mocks for standardized tests like the SAT, ACT, GRE, GMAT, TOEFL and IELTS. She lives in your Dock, posts native macOS notifications, runs on Apple silicon and Intel, and keeps your plan on your machine.
Native on macOS
A real Mac app — not a browser tab pretending to be one.
AskSia installs from a .dmg and behaves like a first-class Mac citizen.
Lives in your Dock
Open Sia like any Mac app — one click from the Dock or Spotlight, a full window with native traffic-light controls, ready the moment you sit down.
Native notifications
macOS notifications nudge you when a plan day unlocks or a mock is scored — so your prep keeps moving without you living in the app.
Apple-silicon fast, Intel too
A native build for Apple silicon (M-series) and Intel Macs, code-signed and notarized. Review your plan and saved aids offline after first launch.
What Sia does
A study agent that builds — not a chatbot you have to drive.
Drop a PDF, record a lecture, or just ask. Sia studies with you and turns it into something you can study from.
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 Mac 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 Mac. 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.

Common questions
Before you download
Is the AskSia Mac app free?
Yes. The AskSia Mac app is free to download for macOS, 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 Macs does it run on?
AskSia for Mac runs on macOS 12 or later and is a native app for both Apple silicon (M-series) and Intel Macs. It lives in your Dock, supports native macOS notifications, and the download is code-signed and notarized by Apple so macOS verifies it before it runs.
What can Sia do on the Mac 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 Mac app or a web wrapper?
It's a Mac app you install from a .dmg: it lives in your Dock, posts native macOS 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 Mac build is code-signed and notarized by Apple, so macOS verifies the app before it runs. AskSia is used by more than 2 million students worldwide. You can uninstall it at any time by dragging it to the Trash.
Is there a Windows version?
Yes. AskSia also has a native Windows app for Windows 10 and 11 with the same study features — see the AskSia for Windows page.
