How it works

1. Build your profile

Enter the patient's age, medical history, and what matters to you — distance limits, which procedures are dealbreakers, placebo tolerance, and more.

2. We search ClinicalTrials.gov

Every actively recruiting interventional trial for your condition is fetched in real time from ClinicalTrials.gov. No stale spreadsheets. Trials added today appear today.

3. Get a ranked list

Trials are scored on eligibility, treatment odds, and your preferences. Dealbreakers are flagged but kept visible — so you can change your mind.

Everything you need — nothing you don't

AI-powered matching

Gemini AI normalizes condition spelling, understands synonyms and abbreviations, semantically detects conflicts with your comorbidities and medications, and generates plain-English summaries for every trial.

Smart eligibility matching

Age, sex, comorbidities, and current medications are checked against exclusion criteria automatically.

Distance-sorted trial sites

Every site is ranked by drive distance from your ZIP. Contacts shown right there — one click to call or email.

Flexible dealbreakers

Mark delivery methods, procedures, or free-form conditions as dealbreakers. Excluded trials stay visible — so you can reconsider.

Private and transparent

Your profile is saved only in your browser — no tracking, no emails, nothing stored on our servers. When you search, anonymized health data (no names) is sent to Google Gemini AI to improve matching. Clifton is fully open source so you can verify exactly what it does.

Share with family & doctors

Star your top trials, then export a formatted action plan as a PDF, copy it to share via text or email, or download as a text file.

New trial alerts

Clifton remembers the last search results. Run it again any time — new trials that appeared since your last check are highlighted automatically.
