Use tool ↗About Liner
Liner is an AI search engine aimed at students, researchers and professionals who need answers they can verify. Answers come with sentence-level citations that open the source in one click, Liner Scholar finds and compares academic papers for literature reviews, and Liner Write drafts documents next to the search results. Paid plans open a large menu of third-party models for chat and image generation. Liner started as a browser highlighter and still ships a Chrome extension. It is made by Liner, Inc., a Seoul-headquartered company founded in 2015 by Luke Jinu Kim and Chanmin Woo; the product moved to its current shorter domain in 2024.

Pros & cons of Liner
Liner is a good fit for students and researchers who want cited answers and a paper finder in one subscription, and who will actually click through the sources. Casual users happy with a general chatbot, or anyone who dislikes ads and tight credit limits on the free plan, will find less value.
Pros
- Sentence-level citations make answers checkable
- Scholar mode focuses search on academic papers
- Paid plans include many third-party chat and image models
- Annual billing brings Pro under $15 a month
Cons
- Free credits run out after a few tasks and answers show ads
- No refunds on subscriptions
- Product spans search, scholar and writing, which can blur what each plan unlocks
Best for
- Graduate students building literature reviews
- Professionals fact-checking claims before publishing
- Students who want citations attached to every answer
Not for
- Users who need generous free usage without ads
- Teams needing an API or self-hosted deployment
Watch out: Subscriptions renew automatically and Liner does not refund them, so cancel before a free trial or billing period ends. The old getliner.com domain no longer serves the product.
