버그 없는 퀄리티 높은 변형 문제를 만들어요.
학교별 출제경향과 난이도를 반영해요. 같은 지문이라도 학교마다 다른 문제가 나와요.

빈칸추론, 순서배열, 어법, 요약문 등 다양한 유형을 지원해요.

어떤 지문이든 변형 문제로 만들 수 있어요. 범위만 고르면 돼요.

방금 친 시험 지문도 그날 안에 변형 문제로 만들 수 있어요.

하나의 지문으로 11가지 학습자료를 만들어요.
Dear members, thank you for your interest in the 1upcoming/upcome reopening. 2Unexpected/Unexpectedly electrical issues 3were/was discovered, 4caused/causing the work to take longer.
It 1were/was the first carnival for Cassie. She 2had only heard/has heard about it. The 3twinkled/twinkling lights made her 4jump/to jump with joy.
There 1is/are no better way to 2influence/to influence an audience than by 3opening/opened up with a personal story, a tried way of 4bonding/bond with strangers.
The emphasis on learning from the ingroup takes 1little/few account of individuals. While we may 2dislike/disliking people, we still copy them, 3distinguished/distinguishing groups by color.
Despite learned behaviors 1forming/formed in childhood, preferences can 2change/be changed. There is 3less/more flexibility than most think — for those 4eager/eagerly to break habits.
The emphasis on ingroup learning takes 1little/much account of individuals. We 2ignore/copy people we dislike, distinguishing groups by 3simple/complex color coding.
Taste preferences can 1change/persist throughout life. There is 2less/more flexibility than most think — good news for those 3eager/reluctant to break bad habits.
Teen conformity is studied by putting teens in situations where they go 1against/along the group. Willingness 2peaks/declines at 14, then it 3decreases/increases sharply.
Plastic came to 1symbolize/disprove convenience and the American dream. After rapid adoption, 2concerns/cheers emerged. The industry was 3slow/quick to deflect these worries.
As Kuhn proposed, our propositions about the world are 1embedded/excluded in paradigms. Even exact measurements are only 2sensible/dubious from within. Major progress is a 3horizontal/vertical shift.
Thank you for your 1interested in the reopening. Issues were 2discovered, 3caused the work to 4be delaying.
Cassie 1has only heard about it. The 2twinkled lights made her 3to jump. She 4had been imaging balloons for long.
There is no better way to influence an audience than 1by opened up with a story. It's a tried way of 2bond with 3strangers.
Behaviors 1formed in childhood can 2be changed. There is more flexibility than people 3thinks.
We need to understand the 1hidden history of plastics. After rapid adoption, plastic 2symbolized convenience and 3poverty of the dream. The industry was quick to 4support concerns.
Our 1objections are 2embedded in paradigms. Exact measurements are only 3sensible within. Progress is not a move to a more 4flawed paradigm.
Teens go 1against the group readily. The willingness 2reaches a peak around 14, then it 3increases with age.
The emphasis on ingroup learning takes 1much account of individuals. We may dislike some yet still 2ignore them, 3unified by color codes.
Dear members, thank you for your 1i in the 2r. 3U electrical issues were 4d.
It was the first 1c for Cassie. She had been imaging 2c balloons and 3d candies.
There is no better way to 1i an audience than by 2o up with a 3p story.
The emphasis on ingroup learning takes 1l account of individuals. Groups are 2d by simple color 3c.
Taste preferences can 1c throughout life. There is more 2f than most think — good news for those 3e to break habits.
Welcome to a new season of High School Magazine. To start off the new school year on the right foot, we asked some of our recent graduates to give us tips on how to succeed in the coming year and beyond.

서울대 · KAIST 출신의 기획자, 네이버 · 카카오 · Flex 출신의 AI 개발자가 함께 만들었어요.
학원 강사를 위한 도구는 많지만, 실제 빅테크 AI 개발자가 만든 서비스는 없었어요. 당근 · 카카오 · Flex · 네이버에서 수백만 사용자를 경험한 팀이, 선생님들이 진짜 쓸 수 있는 도구를 만들기 위해 뚝딱을 시작했어요.
"솔직히 처음엔 AI가 만든 자료를 잘 안 믿었어요. 시중 사이트도 한두 번씩은 다 써봤고요. 버그가 너무 많고, 퀄리티도 별로였어요. 근데 뚝딱은 진짜 바로 써도 되는 문제들이 많더라구요. 제가 5년 넘게 노트에 정리해놓은 거랑 꽤 비슷하게 나와요. 요즘은 학원 자료 대부분 여기서 만들어요. 뚝딱팀에서 학교 출제 경향에 맞는 문제 만들기를 오픈 전 베타로 테스트해달라는 연락을 받아서 봤었는데 이건 진짜 대박이에요. 이건 오픈되면 이것만 쓸 것 같아요."
"서술형 문제 만드는 게 진짜 일이거든요. 시중 사이트들 보면 서술형 자체가 없는 곳도 많고, 있어도 유형이 한두 가지뿐이에요. 그런데 뚝딱은 한 줄 영작, 어순배열, 빈칸 쓰기 같은 다양한 유형이 다 돼요. 퀄리티도 그대로 시험에 내도 될 만큼 잘 나와서, 내신 준비할 때 손이 많이 가던 부분이 진짜 줄었어요."
"대치동에서 오래 가르치다 보면 좋은 문제가 뭔지 감이 오는데, 변형 문제 사이트들 거의 다 결제해서 써봤지만 퀄리티가 많이 떨어지거든요. 그런데 뚝딱은 좀 결이 다르더라고요. 어법이나 어휘 변형에서 시험이 짚을 만한 포인트를 잘 잡아요. 학교가 6~7개씩 되니까 자료 정리가 늘 일이었는데, 학교별 폴더가 분리되는 것도 도움이 많이 돼요. 이번에 나온 워크북도 제가 원래 쓰던 양식은 아닌데, 바로 교재로 써도 될 만큼 디테일이 살아있어서 좀 놀랐어요."
