What is Liner?

Liner is a professional AI agent platform that helps users complete search, research, and writing tasks with accurate, source-based results. The platform offers three core products: Liner for everyday search, Liner Scholar for academic work, and Liner Write for professional drafts. Liner Search is designed for users who need reliable answers grounded in real facts, with citations that can be checked in one click. It also supports follow-up questions and mind maps to help users deepen their understanding of complex topics. Liner Scholar is built for academic research workflows, helping users find papers, compare studies, strengthen writing with citations, and generate literature reviews. It is designed for students, PhD candidates, professors, research scientists, and academic users who need paper-based research support. Liner Write helps users search, write, edit, verify, and polish content in one window. It supports professional writing outputs such as emails, newsletters, reports, business proposals, internal updates, and client-facing documents. Liner’s broader agent tools include hypothesis generation, hypothesis evaluation, citation recommendations, literature reviews, research tracing, survey generation, survey simulation, and peer review support. Users can access Liner, Liner Scholar, and Liner Write through one subscription rather than subscribing to each product separately. By combining accurate AI search, cited answers, academic research workflows, literature review tools, professional drafting, editing, verification, and research agents, Liner helps users turn reliable information into high-quality work.

    How to get refund for yearly subscription!

    Date: Apr 22 2025
    Summary

    Glad I got a refund as the yearly amount was almost the same as 3 weeks of my rent. $$$ And their website says they are strict and don't give refunds.

    Positive

    Hey!
    If you, like me, forgot to cancel your free trial and got charged a huge amount, then do this!

    Contact Liner through their "Contact Us" section on their website and write something saying that you live in the EU and are therefore eligible for a refund within 14 days of starting the paid subscription.

    That's what their terms and conditions say. If you don't say this, I don't think they accept any other reason to refund the amount.

    I hope this helps someone! x

    Negative

    how easy it is to forget to cancel the free trial.

    LINER AI review

    Date: Jun 10 2024
    Summary

    You'd be better off using other copilots like sider, or monica. This is absolute garbage. Its a waste of your money, and they charge you without authorization.

    Positive

    No pros, it's absolute garbage. It makes me want to jump off a building. I wouldn't recommend this to anyone.

    Negative

    The UI sucks.
    Glitchy.
    Hard to use.
    Overpriced.
    Garbage.

    Fraud, Cheat, Horrible Company-STAY AWAY

    Date: Nov 24 2024
    Summary

    Fraud, Cheat, Horrible Company-STAY AWAY.

    Positive

    No Pros. Every thing is bad there. As IT people, they don't have simple common sense. The user query is displayed on the screen in bold and big fonts. What???? the person sitting in neighbor to you can read it easily. Are you mad? Why it is so slow even after paid version? Explain me, how you are better than ChatGPT?. I used both and realized ChatGPT is worth to pay $20 per month. Liner is a JUNK. They don't refund money. They want free money.

    Negative

    If you upgrade, yearly they charged mere more $200, within a month I decided not to use since it was very slow all the time, crashing again and again, so many :something wen wrong" errors. THEY DO NOT REFUND MONEY.
    THIS IS A CHEAT FRAUD COMANY. As AI company, they don't have simple common sense to hyperlink email to support@getliner.com. if click this email (blue link), it keeps going to getliner.com and not to email.

    Encourages cheating

    Date: Aug 28 2024
    Summary

    Well, if your goal in college is to get a degree rather than and education, this might be one way of skating through.

    It doesn't matter how easy it is to use, what support and design it has, and if it's free. If the product doesn't do what it's supposed to do, those things are irrelevant.

    Positive

    Since this ad encourages cheating, it's hard for me to say anything positive. Well, at least it presumably gives an explanation along with the answer (see below).

    Negative

    I just saw an ad for Liner on Youtube. It said that if you are short on time answering questions, just C&P the question into Liner to get the answer along with an explanation.

    I also asked, using the scholar version, about published research in a particular field by a given researcher but not from an English-speaking country. It claimed there was none. A search using an Internet search engine gave results..

    LINER AI HONEST REVIEW.

    Date: Nov 16 2023
    Summary

    So far my experience has been good especially on the search reviews and PDF summaries.The experience on YouTube is also quite nice.
    I would recommend improving on the time it takes to fetch information from sources, and also make the responses more personal to enhance the human like experience.

    Positive

    Information is up to date.
    Search and pdf summaries are by far the best features.
    Offers references on the spot.
    Nice interactivity because it provides for follow up questions.
    The free trial is also reasonable because of the high number of questions it allows per day.

    Negative

    It takes quite some time to fetch information from sources and even sometimes fails to find the answers.
    Customization and personalization of responses is not that good.Sometimes it will just combine the answers from its sources directly without adjusting them.
