What is the AskSia Windows app?
AskSia for Windows is a free, local AI study agent for PC. Give Sia a goal and the agent manages the full process: reading your materials, building cheat sheets, diagrams and quizzes, writing a dated study plan, and adjusting it daily from your results. It also delivers complete test preparation, with exam-faithful, full-screen mock exams for standardized tests like the SAT, ACT, GRE, GMAT, TOEFL and IELTS. The app pins to your taskbar, posts native Windows notifications, runs on 64-bit Windows 10 and 11, and keeps your plan on your machine.
How to Study with AskSia Agent
Give Sia a goal or your materials, and the agent plans the work, builds the study aids, runs the sessions, and adjusts the plan from your results. All in a native app on your PC.

Try the plan builder
The same math Sia runs in the app. Drag or type, no signup.
This is the same builder inside the app. Set the numbers once and the agent keeps adjusting the plan from how you actually do.
Reachable with consistent prep, based on students near 1,210 with a similar window.
Forecasts are pace estimates, not promises. In the app the plan re-calibrates daily, and the diagnostic returns a banded score: a range, not a fake single number.

What is a local study agent?
A study agent is an AI that does multi-step study work for you: it reads your materials, builds study aids like cheat sheets and quizzes, plans multi-week goals, and adjusts the plan from your results. Local means it runs as a native app on your own computer, in this case a code-signed Windows app, with your plan and files kept on your machine instead of living in a browser tab.
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.
How does the SAT prep path work?
You set three numbers: current score, target score, and days until your test. Sia forecasts the gain and weekly pace, then writes a dated calendar in five phases: Diagnose, Build, Drill, Mock Calibration and Final Mock Run. Day 1 is a 20-question baseline that returns a banded score, and every day after is rebuilt from your real results.
Which tests can it mock?
The same diagnose, drill and 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 agent. See the AskSia for Mac page.
