푸리 - AI 풀이과정 분석 수학 노트

Do you understand the explanation, but get stuck again when you try to solve it on your own?

Puri is an AI math tutor that reads your written solution, not just the correct answer.

If you solve past exam questions or your own workbooks just like you would in a note app, the entire process—from grading to solution correction—is handled in one go.

Here are App Store reviews from students who have already tried it.

"It is helpful because it points out everything from calculation errors to valuable insights."

"I like that it analyzes my solution."

"It recognizes my solution well, and the analysis is neat, so I think it is good."

■ Look at the Solution, Not the Answer

If you only check the answer, you move on without knowing where you went wrong. Puri reads the equations and solution flow you wrote on paper and points out where the direction diverged.

It acknowledges the parts you went right first and suggests just the next step you can try.

Example) "The equation for finding the intersection point was correct. This time, shall we set the slope of the tangent to P to 2t?" Since the answer key isn't displayed in its entirety, you can finish the remaining problem-solving on your own.

■ Double-check your answers

Problems solved by intuition are easy to get wrong again in the actual exam. Even for correct answers, a question is posed to verify your understanding of the concept.

e.g., "If the velocity is 0, does the direction of motion necessarily change?"

■ Import your workbooks as is, as PDFs

Bring in anything that is a PDF—from academy textbooks and commercial workbooks to school handouts—and solve them with a pen.

Simply select from the Files app, share a PDF received via messenger, or drag and drop using AirDrop.

You can even upload thick compilation textbooks. The imported workbooks stack in your workbook shelf along with their covers, allowing you to continue solving from where you left off. ■ Includes 56 sets of past KICE exams and academic achievement tests

Open them immediately without needing to download the CSAT, 17 sets of June and September mock exams (2022–2027 academic years), 21 sets of Grade 1 Achievement Tests, and 18 sets of Grade 2 Achievement Tests separately.

Select by grade chip and find the materials in the shelves organized by grade. Solve problems by writing and erasing directly on the test paper without printing.

■ Grading is complete upon submission

Scores are automatically generated once you write down your answers and submit. You don't need to flip through answer keys to check numbers; you can view correct and incorrect answers at a glance and skip directly to the analysis for any questions you have.

■ Review the process in the order you solved it

With the solution replay feature, you can review your entire process from the beginning. Recall what you were thinking when setting up the equations based on the points highlighted by the analysis.

■ Incorrect answers are collected in the error notebook

Problems are categorized and organized into incorrect answers, analyzed questions, and corrected questions. If you solve the problems again after grading, they are added as a new set, so your initial solution and the re-solved solution do not get mixed up.

Problems you got wrong on your test paper are also uploaded to your error notebook along with past exam questions.

■ Handwriting as comfortable as paper

It is equipped with fountain pens, ballpoint pens, highlighters, erasers, and lasso tools. You can choose thicknesses from 1 to 100 and select the eraser size you prefer.

If you zoom in with two fingers, you can write neatly in small letters even in narrow margins.

Recommended for these students:

• High school seniors and repeaters preparing for the CSAT Math exam using an iPad and Apple Pencil

• Students preparing for mock exams using the High School Achievement Test for 1st and 2nd year students

• Students who have academy textbooks or workbooks in PDF format

• Students who understand the explanations but don't know where they get stuck when solving problems on their own

• Students who want to review their solutions and solve problems again rather than just grading and stopping

There are no ads in the app. Focus solely on your studies.
