About Ask DrugCentral
Ask DrugCentral helps you explore drug properties, biological targets, and indications using natural language. Sample questions offer starting points, and linked drug cards let you check the underlying records.
General architecture
- Ask a questionThe browser sends your question to the same-origin Django chat API.
- Retrieve and generateThe API forwards the question to the configured DrugCentral retrieval-augmented generation (RAG) service, which returns an AI-generated answer.
- Explore the answerThe app resolves cited drug-card names and displays the answer with links to drug records.
Using the assistant
Each request is independent; previous questions are not sent as conversation history. You can edit a sample before submitting, retry a failed request, or switch back to normal search. Drug links open in a new tab so your question and answer stay available.
Answers may contain mistakes or omit information. Verify details against DrugCentral records and original sources.
AI can make mistakes. Verify answers against the original sources before relying on them.
