What is Liner.ai?
Liner is a specialized AI search engine designed to meet the rigorous standards of academic and professional research. By connecting you to a database of over 460 million scholarly papers, it eliminates the guesswork and hallucinations common in general-purpose AI, providing you with a reliable foundation for your work.
Whether you are a PhD candidate or an industry professional, Liner streamlines the transition from initial hypothesis to final citation. It transforms the often-tedious process of literature review and source verification into a structured, high-speed workflow that prioritizes accuracy and transparency.
Key Features
- 🔍 AI Research Agents: Deploy specialized agents to automate complex tasks like generating testable hypotheses, conducting literature reviews, and simulating surveys. These agents scan millions of papers to provide citable insights, allowing you to focus on high-level analysis rather than manual data gathering.
- 📑 Line-by-Line Precision: Every statement generated by Liner is backed by a specific, verifiable source. By providing direct links to original papers for every sentence, the platform ensures you can fact-check claims instantly and maintain the highest level of academic integrity.
- 🧠 Deep Research Reasoning: Complex queries are broken down into logical, transparent steps. Liner shows you the underlying reasoning behind every conclusion, providing a structured report that explains how the AI arrived at its answer through specific evidence.
- 🎓 Scholar Mode & Automated Citations: Instantly format your findings into clean, academic-ready citations. You can filter results by journal ranking, year, or citation count, then copy and paste the references in your required format to save hours of manual entry.
- 📊 Visual Insight Tools: Synthesize information using automatically generated mind maps, flowcharts, and graphs. These visual aids help you identify connections between different research papers and domains that might be missed in traditional text-based searches.
Use Cases
- Accelerating Literature Reviews: An industry researcher tasked with a project on a tight deadline can use the Research Tracer and Literature Review agents to summarize the current state of a field in hours rather than weeks, saving an estimated 10-15 hours per paper.
- Developing Research Hypotheses: Graduate students struggling to narrow down a thesis topic can use the Hypothesis Generator to turn vague ideas into clear, verifiable research questions based on existing gaps in the literature.
- Verifying Technical Documents: Professionals can upload large PDFs or datasets to Liner. The AI extracts key insights and links every summary point back to the original source text, making it easy to verify data points in long-form academic files.
