CoChat

CoChat is a research assistant that helps students and researchers search, organize, and verify academic sources. It searches across more than 200 million papers pulled from major academic databases, including ArXiv, PubMed, OpenAlex, Semantic Scholar, Crossref, Europe PMC, and CORE, and flags citations that appear fabricated or misquoted. Beyond search, it offers a collaborative workspace where teams can organize literature, compare answers from different AI models such as Claude, GPT, and Gemini, and export findings into documents. The tool targets students and researchers at universities, with the product page citing users at institutions including Columbia, Cambridge, and Michigan, as well as teams collaborating on literature reviews. Access starts with a free, no-card-required signup, though the site does not list detailed paid pricing tiers. CoChat is built on the open-source Open WebUI project and connects to more than 200 third-party tools, including GitHub, Notion, Figma, Google Drive, Zapier, HubSpot, Atlassian, and Supabase. The company behind it, CoChat Inc, is a small team of one to ten people, according to its own site, with a stated founding date of December 2025 — worth noting for anyone expecting an established, battle-tested citation-checking system rather than a recently formed one.
