I installed the app by misunderstand, and it required me to enter unnecessarily detailed personal information. I also touched the "Unsubscribe" button, but it didn't work. Other buttons worked fine.

안녕하세요, 서예빈님. 앱 설치 과정에서 개인 정보 입력 요구와 구독 취소 문제로 큰 불편을 겪으셨군요. 우선 뤼튼 서비스 내에는 구독 취소라는 명칭의 버튼이 별도로 존재하지 않습니다. 혹시 어떤 경로에서 해당 버튼을 보셨는지 조금 더 자세히 설명해 주시면 문제 원인을 파악하는 데 큰 도움이 됩니다. 이와 관련하여 도움이 필요하시거나 계정 및 결제 문의가 있으신 경우, 아래의 뤼튼 공식 고객센터 사이트를 통해 문의를 접수해 주시기 바랍니다. 뤼튼 고객센터 : https://help.wrtn.ai/ 불편을 드려 다시 한번 사과드리며, 신속한 처리를 위해 최선을 다하겠습니다. 감사합니다. 뤼튼 드림.

GPT-4 & Turbo. Free and forreal. It's in Korean, but don't be fooled. My only issue is that as of recent they've implemented a FILTER, but it is good for general use.
