LINER is an AI-powered browser extension developed by LINER Global that acts as a web and PDF highlighter and AI assistant. Its core feature allows users to highlight text on any webpage or PDF, then use AI to summarize, explain, or generate related content directly within the browser, powered by ChatGPT. This tool is primarily built for students, researchers, and professionals who consume a lot of information online and need to quickly grasp key concepts or extract relevant details. It fits into a workflow whenever a user encounters a lengthy article or document and needs to understand its essence, generate questions, or get quick definitions without leaving the page. LINER works across most websites and local PDFs, offering integrations with tools like Notion and Evernote for saving highlights.
Why It’s Useful
LINER replaces or complements traditional highlighting tools by adding a layer of AI intelligence, allowing for instant summarization and content generation, which is far more efficient than manual note-taking. For the student preparing for an exam, they can highlight key concepts in an online textbook and instantly get AI-generated explanations or flashcards. For the business analyst researching market trends, LINER allows them to quickly summarize long reports and extract specific data points without opening multiple tabs. The free tier offers basic highlighting and AI queries, while paid plans unlock unlimited AI usage and advanced features like full-text summarization. A lesser-known feature is its ability to automatically recommend related articles based on your highlights, expanding your research scope. It's not more popular due to the crowded market of AI tools and the general hesitancy some users have towards AI integration into their browsing. LINER has a regularly updated blog and responsive support, indicating active development.
