In the information-overloaded society, getting through the noise is becoming increasingly difficult. LINER was made to tackle this problem, helping you/us navigate the deluge of online information more efficiently.

Working as a web-based tool, it aims to streamline your internet browsing experience, allowing you to quickly locate and learn valuable information.

LINER relies on ChatGPT to suggest what you might want to search for next. The idea here is to improve your search experience and tailor it to your specific needs.

In addition, LINER offers a universal highlighter feature across the web. You can use it on articles, images, PDF files, and even YouTube videos. It’s like having a highlighter pen for the internet, allowing you to mark up important points or interesting facts as you come across them.

It uses multi-agent AI systems to break down queries, cross-reference over 200 million academic sources, and provide line-by-line citations for every claim. Recent benchmarks like SimpleQA show it scoring 95.3% accuracy, outperforming tools like ChatGPT and Perplexity in fact-checking, though it might still hallucinate on niche topics.
What are the main features of Liner AI?
Key ones include Deep Research for in-depth reports, Scholar Mode for academic formatting, AI agents for tasks like hypothesis generation, file uploads for PDFs and images, and browser extensions for highlighting web content. You get unlimited simple searches on all plans, plus voice input and cross-device sync.
How much does Liner AI cost?
It starts free with basic access, then Pro at about $96/year for more searches, Max at $180/year for heavy use, and Team plans for collaboration. Prices can vary, so check the site, but the free tier covers light needs without ads after upgrade.
Is there a free version or trial of Liner AI?
Yes, the Free plan gives 3 advanced searches daily and 3 Deep Research monthly, with no credit card needed. It's perpetual, not time-limited, and includes beta features, making it a solid way to test before upgrading, though quotas might limit intensive work.

It uses encryption and keeps your data private, with Team plans excluding uploads from AI training. No major breaches reported in 2025, but always review their policy, as some users worry about cloud storage for confidential work.
What do users say about Liner AI's ease of use?
Many praise the intuitive interface for quick highlights and reports, calling it a workflow changer, but some find the free quotas frustrating or the app occasionally glitchy on mobile. Overall, recent Reddit and G2 feedback rates it 4.2/5 for beginners, with a learning curve for advanced agents.
