TLDR: Ohio University Libraries have introduced Consensus, a new artificial intelligence search engine designed to streamline academic research. The tool, which became available in mid-September, reviews over 200 million peer-reviewed papers to provide summarized answers, visualize key information, and offer direct quotes from scholarly literature. Unlike general search engines, Consensus is specifically trained on high-quality research papers to ensure factual and citable results, aiming to make academic research more efficient and accessible for students and faculty.
Ohio University Libraries recently announced the integration of ‘Consensus,’ an advanced artificial intelligence search engine aimed at revolutionizing academic research for its students and faculty. The new tool, which became accessible through OU Libraries in mid-September 2025, is designed to enhance the efficiency and comprehension of scholarly investigations.
Consensus distinguishes itself by reviewing an extensive database of over 200 million peer-reviewed papers, including content from high-impact journals and the entirety of PubMed. Its core functionality involves summarizing answers to research questions, visualizing crucial information, and providing direct, verifiable quotes from academic sources. This specialized training on high-quality research papers ensures that the information provided is factual and grounded in citable research, mitigating the risk of ‘hallucinations’ or speculative content often associated with general-purpose AI chatbots.
Eric Olson, CEO and co-founder of Consensus, highlighted the tool’s superiority over traditional academic search platforms like Google Scholar. Olson stated that Google Scholar offers a ‘basic experience’ that primarily yields lists of links, whereas Consensus ‘directly answers a user’s question, organizes sources and provides summarized findings with supporting quotes from academic papers.’ He further criticized older technologies for ‘not adapting to all of the cool things we can now do in this new world with AI models.’
Hanna Schmillen, Assistant Dean for Research and Education Services at Ohio University Libraries, emphasized Consensus’s ability to recognize language associations and connect related sources. Schmillen explained, ‘The benefit with AI is that some of that language association is automatically tied into how the LLM (Large Language Model) is designed. In theory, it should help if the training data actually does know to connect Calico to kitten to Siamese cat to feline.’
Robert Ross, Dean of University Libraries, underscored the university’s significant annual investment of approximately $5.5 million in content subscriptions. He noted that while this eliminates many paywalls, some resources remain unaffordable. Ross and Olson are exploring the possibility of integrating Consensus with Interlibrary Loan services, which would enable students to request access to sources not directly held by OU Libraries from other institutions.
Consensus incorporates several safeguards to ensure responsible AI usage. It operates on a ‘search before synthesis’ principle, meaning every response begins with a literature search to guarantee real, non-hallucinated citations. The AI’s summarization capabilities are strictly limited to the retrieved papers, preventing it from ‘filling in the blanks’ with external knowledge. Furthermore, transparent sourcing and attribution are paramount, with every claim cited and every citation clickable, allowing users to easily verify and reference original content. The platform also employs AI ‘checkers’ to verify the relevance of sources before they are used in summaries.
Currently, Ohio University is in the initial stages of promoting the platform, with approximately 150 students having already signed up. Dean Ross expressed confidence in the tool, stating, ‘As a librarian, I feel good that if a student’s using this, they’re not going to get hallucinations, they’re not going to get nonsense, they’re going to get a high-quality answer, which is going to help them in their course.’
