About Find a Trial
Find a Trial is a free, AI-powered clinical trial search engine for patients and caregivers. We make ClinicalTrials.gov searchable in plain language by combining BM25 and MedCPT retrieval with GPT-assisted ranking, returning explained, patient-friendly trial matches in seconds.
What we do
Every active clinical trial in the United States and most of the world is listed on ClinicalTrials.gov, but the database is built for researchers. A patient looking for the right study has to know precise medical terminology, manually scan dozens of records, and decode dense eligibility criteria. We close that gap with an AI layer that maps patient descriptions to the trials they are most likely to qualify for.
How matching works
Our pipeline extracts medical concepts from your description, retrieves candidate trials with hybrid keyword + semantic search, ranks them with GPT for clinical relevance, then explains each result in plain English. See How it works for the full technical breakdown.
Data sources
- ClinicalTrials.gov — US registry of clinical studies, refreshed daily.
- NIH RePORTER — National Institutes of Health funded research projects.
Editorial standards
Educational content on Find a Trial — FAQs, guides, condition overviews, and trial summaries — is written and reviewed by our editorial team and grounded in the underlying study protocols and peer-reviewed literature. Plain-English trial summaries are AI-generated and labeled as such. Nothing on Find a Trial is medical advice. Treatment and trial-enrollment decisions belong to you and your clinicians.
How we are funded
Find a Trial is free for patients. We do not charge to search, do not run third-party ads on patient-facing pages, and do not sell patient data. The platform is supported by partnerships with research institutions and trial-recruitment programs that pay for matched referrals when patients opt in to be contacted.
