Your feedback about the ads has been shared with our team for review. If you have any questions, please feel free to reach out to our support team. — Liner Team ### 5/5 — Stock peer groups, analysis *2026-07-29, version 26.30.0* For this task, I thought the response was outstanding. Thorough & comprehensive ### 5/5 — Absolutely amazing AI, not-so-amazing app or pricing *2026-07-15, version 26.29.0* I use a mac. Do not download the Liner AI app off the App store, just download it off the web. This app store one is based off the ipad and is super buggy, slow, and uncustomizable on macbook. However, if u do get the web download app version, this AI is amazing, with a twist. It is absolutely wonderful to use for research. Is the app very CPU-load heavy? Sure. But there is not a single AI that can beat this in terms of low hallucinations and accurate research. The second catch other than to not dowload the app from the app store is that this AI is expensive. 1000 credits a month for 15$ a month (paid yearly btw) equates to make 5-6 questions on the really advanced research stuff with Liner Scholar or Liner Write. The good thing tho is that Liner sometimes reimburses u credits (500 usually) if the ai agent doesn’t do something correctly or if u test some new features. ### 1/5 — 리뷰작성 안하는데 진짜 최악이라 남깁니다 *2026-03-22* 프리미엄 요금제 가입되어있는데 계속 무료체험하라고 띄우는거 부터 불편하고 ux는 신경도 안쓴듯하네요. 답변이 생성되어서 복사하려면 전체 복사해야 그나마 복사가 잘 되고 일부분 내용만 복사가 잘 안됩니다. 또 질문이 좀 쌓였을때 아래로 스크롤하다보면 갑자기 대화의 가장 위로 이동하는 버그도 있고 모바일은 그나마 나은편인데 특히 pc에서 이 현상이 진짜 불편하게 느껴집니다. 지금 ui/ux에 관해 불만이 있다고 얘기했지만 사실 모델 선택할때 라이너를 선택하고 질문한 답변에 대한 신뢰성이 검색기반이라 높다고 홍보를 하는데 답변 나온거 보고 있으면 매끄럽지 않고 출처 표시해주는거 외에 장점이라곤 느껴지는게 없습니다. 앱 평가는 이 앱을 처음으로 해보는데 진짜 여러모로 불편한 점이 많습니다. 개발하고 내부에서 사용을 해보고 출시한게 맞나 싶네요. 애니메이션이나 ui 자체는 기존 llm 서비스들과 비슷해서 익숙한건 좋은데 디테일에 더 심경써주시면 좋을거 같습니다 **Developer response:** 안녕하세요, 라이너팀입니다. 사용에 있어 기대에 미치지 못한 점으로 불편을 드려 진심으로 죄송합니다. 말씀해주신 소중한 피드백은 관련 팀에 전달하여 더 나은 서비스로 개선될 수 있도록 하겠습니다. 앞으로도 더욱 편리하게 이용하실 수 있도록 노력하겠습니다. 감사합니다. ### 4/5 — 앱도 기능개선좀 *2026-03-08, version 26.9.0* pc기능들 앱에서 쓸수있게 해주세요 ### 5/5 — 라이너 앱이 유료 결제 되었어요 *2026-01-19, version 26.3.1* 라이너 앱 대화창에 1년 무료 구독 배너가 뜨길래 느르고 구독신청 했는게 5천원 결제가 됐네요. 제 의사와 다르게 결제가 되어서 환불 요청하고 싶은데 어떻게 하나요? 오늘 구독신청 직후 바로 취소했습니다 ### 5/5 — Status *2025-12-31, version 25.52.0* Awesome ! ### 5/5 — A solid AI for coding and others *2025-12-14, version 25.50.0* I really use Liner for a lot and as my general AI, and even tho I wish it had more support for image and video generation, it’s a solid overall platform ### 1/5 — Disgusting and biased . *2025-12-14, version 25.50.0* I cannot understand how me making a simple request to fix my grammar on Please correct my grammar and spelling don’t change the words “ that statement is so hurtful . Women and girls around the globe suffer just for the fact they they are women . Womanhood is not a costume , it is not transphobia it’s the fact. We are not cis women we are simply women . Woman are persecuted under Sharia law , women and little girls are mutilated for having female body parts . Women endure so much and there is nothing in this world more beautiful than the God given power to build life . We must protect our girls , period pains and disorders that come from it aren’t something that is “Gatekept “ it’s a grooling process . Women’s health care is overlooked , companies poison our tampons , women’s necessity’s are filled with chemicals that hurt our reproductive organs . Women’s menopausal healthcare is not taken seriously.” Cannot be done because it is deemed as hateful . I have written many opposing essays claiming the opposing argument and have never had an issue . This app is political and promotes propaganda. I am utterly disgusted as I am simply unable to understand where that essay was disrespectful. I love everyone . The AI has me links to me saying I am “gaslighting them “ and I find that unpleasant. I will submit a screen recording if you can provide a email to do so .I PAYED 200$ FOR THIS ### 5/5 — Research Focused AI Search *2025-12-03, version 25.47.1* Their’s only one better research based AI that I know of in the game that’s better! ## Frequently asked questions about Liner ### What does Liner AI do?
