Cited Proof vs. AI in Clinical Research
Over the last 20 years in clinical research, I have learned to be careful about answers that sound right. In this field, there is a real difference between a response that feels plausible and something you would be comfortable relying on during study conduct, monitoring, or an audit. That distinction is a big part of why I pay close attention to AI. I think tools like ChatGPT, Claude, Gemini, and Copilot are impressive. I use them myself, and I think anyone in this industry who ignores them is making a mistake.
Where I part company with some of the current AI hype is document review. Clinical research documents are not just content to be summarized. A protocol, an amendment, an informed consent form, an investigator brochure, a pharmacy manual, or sponsor guidance can drive real decisions. Sometimes the issue comes down to one sentence. Sometimes it is a qualifier, a visit window, or whether a later amendment changed what the base protocol said. In that setting, a polished answer is not enough. You need to know what the document says, where it says it, and whether something else in the study file says it differently.
General AI tools were not really built for that. Their strength is flexibility. They are good at summarizing, brainstorming, translating dense text into plain English, and helping you get started. But that same flexibility can become a weakness when the work depends on exact language. AI is very good at producing a response that reads clearly and confidently even when the underlying support is incomplete, blended, or a little too loosely paraphrased. In a casual setting, that may not matter. In clinical research, it can matter a great deal.
Privacy belongs in the conversation too, and it is not a trivial point. Many sponsors, CROs, and sites are still cautious, and rightly so, about what can be uploaded into general-purpose AI systems. Sometimes the rules are clear. Sometimes they are not. Either way, it is one more reason I do not think general AI should be the default tool for routine review of study documents.
The bigger operational issue, in my view, is that study questions rarely live inside one clean piece of text. A simple question may touch the protocol, a later amendment, the ICF, and a site-facing document. Those sources may line up, or they may not. When they do not, I do not want a system that smooths that over and gives me a tidy blended answer. I want to see the tension. I want the relevant passages in front of me so I can judge them myself.
DocCite takes a narrower approach, on purpose. It is not trying to be an all-purpose assistant. It is built for a specific job: reviewing your own clinical research documents locally, searching across them, and showing the cited passages behind the result. That may sound less ambitious than what people now expect from AI, but for this kind of work, I think it is a better fit. When I am reviewing study documents, I do not need a tool to sound smart. I need it to stay close to the source, keep document versions distinct, and make verification easy.
I do think AI has an important place in clinical research. It can help with drafting, training, summarization, and early-stage thinking. Used well, it can save time and improve clarity. But I draw a clear line between using AI to help me think and using a tool to help me review source documents. Those are different tasks. When I need help thinking, AI can be excellent. When I need to review clinical research documents and stand behind what I found, I want exact passages, clear citations, local privacy, and a system that does not hide uncertainty when the documents do not fully agree. That is what DocCite is built to do, and it is why I think it is the better tool for this job.
