Query it here
The research agent queries UniChem directly — no account, no API key — and every answer links back to the record it came from. Ask in plain language and it writes the query.
Questions
Can I search UniChem without writing code?
Yes. The research agent queries UniChem directly, with no account or API key, and cites the record behind every answer. Ask in plain language — for a gene, a protein, a compound or a study — and it builds the query for you.
Can I reuse data from UniChem?
