Client & The Problem


Healthcare professionals often struggle to quickly identify the best treatment options tailored to a patient’s condition, especially when information is scattered across multiple drug databases and manuals. The client sought an AI-powered tool that could provide instant, reliable, and medically sound recommendations—without replacing professional judgment.

Solution


We developed a web-based AI Medical Chatbot that allows doctors, pharmacists, and even veterinarians to input free-text descriptions of patient diagnoses and clinical traits. The chatbot processes these inputs using AI (OpenAI API + LangChain) and references data from CBIP, Delphicare (APB), and the MSD Manual to recommend drug classes, specific medications, dosages, and treatment considerations. It supports follow-up queries, differentiates between free and paid tiers, and is designed with GDPR compliance.

Results


The chatbot delivered a reliable decision-support tool for medical practitioners. It improved treatment decision efficiency, received positive early feedback from professionals, and was designed with scalability in mind (e.g., language support and future system integrations). Paid users gained unlimited access and saved conversation history, increasing long-term engagement and monetization opportunities.
