RxBulb

RxBulb is a medical AI chat platform that answers clinical and drug questions with clickable citations to peer-reviewed literature and FDA data, validates references, and flags when sources fall short. Built for clinicians, trainees and patients.

RxBulb is a medical AI platform that answers clinical and medication questions with citations attached to each factual claim. Instead of relying on model memory, it builds responses from peer-reviewed literature, FDA drug data and clinical guidance, then links every statement to the paper, label or guideline behind it. When the available sources do not adequately cover a question, the platform says so explicitly rather than filling the gap with a guess. The audience is broad. Physicians, pharmacists, researchers and medical students are the primary users, and the site also positions itself for patients and caregivers who want to understand their own care. Typical clinician use cases include double-checking a prescribing decision, reviewing interaction concerns before acting on them, and catching up on a guideline between patients. Trainees can use it to look up the evidence behind a recommendation before presenting on rounds and to practice appraising which claims the cited literature actually supports. In practice, a user types a clinical question into the chat interface and receives a concise summary with numbered, clickable citations. A validation step compares each reference against the real source list, and references that are nonexistent or mismatched are stripped before the answer is shown. Questions can be kept as notes and revisited later. Beyond chat, the platform builds drug safety dashboards that draw on FDA adverse event, labeling, shortage and recall data, which can be refreshed on demand. A public library of previously answered questions, covering topics such as GLP-1 drugs, hypertension guidelines and Paxlovid interactions, shows the output format before signing up. Among alternatives, RxBulb sits between general chatbots, which tend to answer in a uniform confident tone with unverifiable references, and traditional resources such as UpToDate, PubMed and drug labels, which require searching several places. It is not limited to a fixed drug list or specialty, and the site states it is an educational reference, not medical advice or a substitute for professional judgment. Access starts with free credits, after which paid monthly or annual plans with a short trial apply.
