§ Private Profile · New York City, NY, USA
AI search engine for academic research, providing cited summaries from over 200 million papers for academic and industry scientists.
Based in New York, New York, Epsilon is an artificial intelligence search engine designed specifically to assist academic and industry research scientists with comprehensive literature discovery and analysis. The software platform scans an extensive database of over 200 million academic papers to generate cited summaries and directly answer complex research questions. It automatically groups relevant publications and patents into distinct categories, such as latest research and key texts, while validating specific scientific claims by extracting direct evidence from the underlying literature. To synthesize complex information for meta-analyses, citation tracking, and brainstorming sessions, the system utilizes advanced GPT-4 technology from OpenAI, powered by comprehensive data sourced directly from Semantic Scholar. Currently operating with a dedicated team of two full-time employees, the enterprise software company Epsilon was officially founded in 2022 by co-founders Viraj Rai and Eshan Agarwal.

Key people at Epsilon.
Epsilon is an AI-powered search engine designed specifically for academic and scientific research. It enables researchers to ask complex research questions and instantly receive synthesized, citation-backed answers by scanning over 200 million academic papers from sources like Semantic Scholar, PubMed, arXiv, and more. The platform streamlines the research process by summarizing relevant passages, organizing papers into libraries, and allowing users to search across their saved documents, thus saving time and improving research efficiency. Epsilon primarily serves research scientists in academia and industry who need quick, trustworthy access to evidence-based information to support their work[1][3][4].
Epsilon was founded to address the limitations of general-purpose large language models (LLMs) and traditional academic search engines like Google Scholar, which often leave researchers with hours of reading to find specific insights. The founders, with backgrounds in AI and scientific research, developed Epsilon to combine AI-driven summarization with direct citation to academic literature, enhancing the precision and trustworthiness of research queries. The platform evolved by integrating datasets from Semantic Scholar and refining its AI to generate research-backed answers, focusing on simplifying repetitive workflows for scientists to enable them to concentrate on groundbreaking research[1][4][6].
Epsilon rides the growing trend of AI augmentation in academic research, addressing the increasing volume and complexity of scientific literature that overwhelms traditional search methods. The timing is critical as researchers demand faster, more reliable tools to synthesize vast datasets and generate evidence-based insights. Market forces such as the expansion of open-access academic databases and advances in natural language processing favor Epsilon’s approach. By improving research efficiency and accuracy, Epsilon influences the broader ecosystem by accelerating scientific discovery, enabling better-informed decision-making, and fostering innovation across disciplines[1][2][4].
Looking ahead, Epsilon is poised to deepen its integration with academic workflows, potentially expanding features like collaborative research libraries, enhanced AI-driven paper analysis, and domain-specific customization. Trends shaping its journey include the rise of AI in knowledge management, increasing demand for reproducible research, and the push for open science. As Epsilon evolves, its influence may grow beyond academia into industry R&D, policy analysis, and education, becoming an indispensable tool for evidence-based inquiry. This aligns with its mission to simplify research workflows and empower scientists to focus on innovation rather than information retrieval[1][6].
