In the crowded field of medical AI, most chatbots project confidence regardless of the evidence. RxBulb takes the opposite stance: it will tell you when it doesn't know. This refusal to guess, backed by a citation validation pipeline, is what makes RxBulb more than another ChatGPT wrapper. It's a clinical reference tool designed for a world where a hallucinated drug interaction could be lethal. RxBulb, built by Rudrasoft LLC in Pittsburgh, positions itself as "Medical AI for Doctors. Medical AI for Patients." The platform answers clinical questions with concise summaries, each claim linked to a clickable citation from peer reviewed literature, FDA drug labels, and clinical guidelines. The site's counter shows over 7,000 clinical questions answered, with more than 6,000 backed by real citations. But the numbers matter less than the mechanism: every citation is validated before the user sees it.
