CoChat is an AI research assistant that verifies every citation against its original paper to prevent researchers from citing misquoted or fabricated sources.
Built on the open-source Open WebUI platform (which has 130k+ GitHub stars and 230M+ downloads), the tool searches across 200M+ real academic papers and flags claims that don't match their sources—addressing a problem where one in four citations in published research misrepresents what the paper actually says.
What happened
CoChat, an AI research assistant built on Open WebUI, launched with features to search across 200M+ academic papers, verify citations against original sources, and flag misrepresented claims before they enter a researcher's bibliography.
Why it matters
One in four citations in published research misrepresents its source, according to the product. By filtering fabricated and misquoted sources, CoChat aims to prevent researchers from building on false claims and passing them forward to others who cite their work.
What to watch
The tool includes side-by-side comparison of answers from Claude, GPT, and Gemini; shared workspaces for advisors and co-authors; and automation agents that monitor new publications and deliver weekly reading summaries. It integrates with 200+ tools including arXiv, PubMed, and Semantic Scholar.

CoChat addresses a well-documented problem in academic publishing: citation misrepresentation. The product cites a statistic that one in four citations in published research misrepresents its source, and frames this as a cascading problem—researchers build on those flawed references, and then others cite them in turn, spreading the error forward. The tool's core innovation is real-time verification, filtering out claims that don't match the actual content of the papers they cite.
The product is built on Open WebUI, an established open-source AI interface with substantial adoption (130k+ GitHub stars, 230M+ downloads, 700+ contributors). CoChat extends this foundation by adding team collaboration features—shared workspaces, live editing, and agent-based automation—positioning itself not as a standalone tool but as a research platform teams can run on. The inclusion of cross-model comparison (Claude, GPT, Gemini side-by-side) suggests the creators view hallucination detection as a multi-AI problem, requiring verification across different models rather than trust in any single AI.
