SAT AI tutor
Stuck on a quadratic or a tricky transition question? SAT AI walks you through the reasoning one step at a time, offers a hint before the answer, writes similar questions for practice and helps you plan your weeks, whenever you study.
01 /What it does
SAT AI is built for one job: helping you understand Digital SAT questions well enough to solve the next one on your own. These are the four things students use it for most.
Paste a question and get the reasoning broken into small steps (the algebra, the grammar rule or the evidence in the passage), not just the letter of the right answer.
“Explain why the answer is C”
Ask for a nudge instead of the solution. SAT AI points you to the next move so you still do the thinking, which is what makes the skill stick.
“Just give me a hint”
Got one right by luck? Ask for a fresh question that tests the same skill at the same difficulty, then check your answer in the same chat.
“Write a similar question”
Tell it your test date, your current score and your target. SAT AI suggests a weekly routine and which course modules and Power-ups to focus on first.
“Plan my next 6 weeks”
02 /Example conversations
Real questions students ask, answered the way SAT AI answers them: short steps, a check of your understanding and an offer to practice more. Switch between a Math word problem, a Reading and Writing transition question and a study-plan request to see how the tutor adapts.

A gym charges a $40 sign-up fee plus $25 per month. Mia has paid $215 in total. How many months has she been a member?
SAT AI
Let's turn the words into an equation. The total cost is the fee plus 25 for every month m: 40 + 25m = 215. Subtract 40 from both sides to get 25m = 175, then divide by 25. Mia has been a member for 7 months.
You
I wrote 25 + 40m. Why is that wrong?
SAT AI
Good question. That swaps the fixed and the variable parts. The $40 is paid once, so it stays a constant. The $25 repeats every month, so it is the one multiplied by m. A quick check: plug m = 7 into the correct equation, 40 + 25 × 7 = 215 ✓. Want a similar question to practice?

Which transition fits: "The study was small. ___, its results were later confirmed by a much larger trial." Options: Therefore, Nevertheless, Similarly, For instance.
SAT AI
Look at the relationship between the two sentences. The first one points out a weakness (a small study). The second one says the results held up anyway. That is a contrast, so you need a word meaning "despite that": Nevertheless.
You
Why not "Therefore"?
SAT AI
"Therefore" introduces a consequence, but being small does not cause results to be confirmed. A quick test for transition questions: say the two sentences with "because" or "but" between them. If "but" sounds right, choose a contrast word.
You
My SAT is in 8 weeks. On my last practice test I got 1180: 620 in Reading and Writing and 560 in Math. I want 1350. What should I do?
SAT AI
A 170-point jump in 8 weeks is ambitious but realistic with steady work. Math at 560 is where the fastest gains usually are. Weeks 1–3: finish the Algebra and Advanced Math modules and do flashcards for 15 minutes every day. Weeks 4–6: alternate lessons with 30-minute custom exams on your weakest topics. Weeks 7–8: one full-length practice test per week and review every mistake.
You
How many hours per week is that?
SAT AI
Around 6 to 8 hours: five 60-minute sessions on weekdays plus a longer practice test or review block on the weekend. Consistency matters more than marathon days. Would you like me to turn this into a day-by-day schedule?
03 /Knowledge base
Before answering, SAT AI matches your question to the SAT Sphere lessons that cover the topic and uses them to guide the explanation. That keeps answers aligned with what the Digital SAT actually tests and with the methods you learn in the course.
Type or paste any SAT question, a concept you are unsure about or a planning question.
SAT AI finds the course lessons that cover your topic and uses them as its reference.
A clear explanation with steps you can follow, a check of the key idea and an offer to practice more.

04 /Use it well
SAT AI is most useful when you treat it like a patient tutor: give it context, ask it to explain and then try the next question yourself. It is a study tool with clear boundaries, so it also helps to know when an answer deserves a second look.
Like any AI, SAT AI can make mistakes, especially in long calculations. Check its steps against the lesson or the answer key.
It is a study tool. Outside help of any kind, including AI, is not allowed during the real SAT.
Your chats are saved to your account so you can come back to them. Avoid sharing personal details you would not write in a study notebook.

What students and parents ask before they start studying with an AI tutor: how accurate it is, whether using it counts as cheating and which plan includes it. Questions about the rest of SAT Sphere are answered in the main FAQ.
SAT AI is the AI tutor built into SAT Sphere. It explains Digital SAT Math and Reading and Writing questions step by step, gives hints, writes similar practice questions and helps you plan your study time. It uses the SAT Sphere lesson library as its reference material.
No AI is perfect. SAT AI is grounded in our course lessons, which makes its explanations more reliable for SAT topics, but it can still make mistakes, especially in long calculations. Always follow the steps yourself and compare them with the lesson or the official answer.
Yes. SAT AI can usually reply in the language you write in, which helps when a concept clicks faster in your first language. SAT Sphere lessons and practice questions are in English, the language of the test, so key terms and quoted passages stay in English.
Using an AI tutor to learn is no different from asking a teacher for help. What matters is how you use it: ask for explanations and hints, then solve questions yourself. During the real SAT, no outside help of any kind, including AI, is permitted.
The full SAT AI tutor is part of Premium Plus, together with every flashcard deck and custom practice exams. Free and Premium include a small daily allowance of messages so you can try it. You can compare all plans on the pricing page.
