Using Clin2.

Plain terms for using the service, and an important note about what Clin2 is — and isn’t.

Last updated October 1, 2026

Medical disclaimer

Clin2 helps you find and understand clinical trials. It is not a medical provider and does not provide medical advice, diagnosis, or treatment. Information here — including human-readable summaries and pre-screen results — is for general understanding only and is not a substitute for professional medical judgment. Always consult a qualified healthcare professional about your care, and never disregard or delay medical advice because of something you read on Clin2.

What Clin2 does

We provide a search engine and clear summaries for clinical trials sourced from ClinicalTrials.gov. We don’t run trials, enroll you in them, or guarantee that you qualify for any study. Eligibility and enrollment decisions are made solely by each study’s team.

Accuracy of information

We work to keep our copy of the registry current and our translations faithful, but trial details can change and our plain-English layer is a summary. The official ClinicalTrials.gov record, linked on every trial page, is the authoritative source. Verify important details with the study team before acting on them.

Clin2 in ChatGPT and other assistants

When you use Clin2 through an assistant such as ChatGPT, Clin2 supplies study information and a preliminary comparison of the facts you shared against a study’s published requirements. That comparison is not an eligibility decision — only the study team can decide whether you can take part — and it can be incomplete, because many criteria (lab values, timing, medical history) can only be checked by the study team. The assistant writes its own replies; Clin2 is responsible for the study data it provides, not for how the assistant words or interprets it. Nothing Clin2 provides through an assistant is medical advice. Talk with your doctor before making decisions about your care.

Acceptable use

Use Clin2 for your own personal, non-commercial purpose of finding and understanding trials. Don’t scrape, disrupt, or misuse the service, and don’t rely on it as a medical or emergency resource. If you have a medical emergency, call your local emergency number.

Your account and data

If you create an account, you’re responsible for keeping it secure. Our handling of your information, including how you can export or delete it, is described in our Privacy page.
