Liner is perfect for anyone who needs to find, organize, and analyze information more efficiently across the web and various file formats. With its AI-powered search capabilities and smart highlighting tools, it saves countless hours of research time while delivering more relevant results than traditional search engines.
Liner is commonly used across educational institutions, research organizations, content creation teams, and corporate environments where information management is essential.
Liner offers an AI search engine with potential, but users report mixed experiences. While the tool boasts over 10 million users and claims to deliver accurate research answers, it struggles with performance and reliability. Some users find the search and PDF summary features helpful, though they note the app can be slow and occasionally provide inaccurate information.
The platform's user interface receives criticism for being confusing and cluttered, which can detract from the overall experience. Potential users should also be aware of reported challenges with subscription cancellations and refund processes. Despite these drawbacks, Liner continues to attract researchers and professionals seeking an AI-powered search solution.
Liner uses AI models from several top companies including OpenAI, Google, and Meta. You can pick from up to eight different AI models depending on what kind of research you're doing. This lets you choose the best AI for your specific question or topic, which helps you get better, more accurate results. The variety of models means Liner works well for simple questions and complex research alike.
Can I use Liner across different devices?Yes! Liner works on most devices and browsers. You can use it as a browser extension for Chrome, Firefox and others, or download the mobile app for iOS and Android. All your highlights, notes, and saved research sync across your devices, so you can start research on your laptop and continue on your phone without missing anything. This makes it really handy when you're studying or working from different places.
What's the difference between the free and paid versions?The free version gives you basic search functions and limited highlighting features to get you started. The paid version unlocks much more, including Expert Mode for deeper research, more highlighting colors, full file analysis for PDFs and documents, image processing, and access to all the AI models. You'll also get better organization tools and can handle more complex research projects. Most serious students and professionals find the upgrade worth it if they do lots of research or writing.
How does the highlighting feature work?The highlighting tool lets you mark important parts of web pages, YouTube videos, and even images. You can use different colors to organize information by topic or importance. After highlighting, you can add notes or comments to remind yourself why that information matters. All your highlights get saved to your account where you can search through them later, organize them with tags, or share them with friends or classmates. It's like having a digital highlighter that saves everything you mark in one place.
Can Liner help with writing assignments or papers?Liner is really helpful for writing projects. It helps you find reliable sources and information faster than regular search engines. You can highlight and save important quotes or facts as you research, which makes it easier to organize your thoughts. The AI can also help summarize articles or explain complex topics in simpler terms. Some users even use it to help draft emails or outline papers. Just remember that while Liner can find and organize information for you, you'll still need to put everything together in your own words for assignments.
