One month free — licensed clinicians in the United States and Canada

This beta is for licensed clinicians who practice in the United States or Canada. Opened August 25, 2026. Use Caydra as an assist. If a color, a pair, or the wording looks off, tell us. We review feedback and update when we can. You are not asked to certify the product or review a hidden homework list.

Who this month is for

  • Licensed clinicians practicing in the United States or Canada
  • MD / DO
  • NP
  • RN
  • PA
  • PharmD
  • Faculty who train those clinicians, at an accredited health-professional school

Patients, the general public, and clinicians practicing outside the United States and Canada are not offered this beta. We still read polite inquiries; we do not send checker access.

How access works

1. One form — Request access. About two minutes. Then go back to patients.
2. We review (that part is on us, not on you).
3. One email, one link: sign in and type the medications when you have a minute. Tell us what to change anytime.

We do not put the working checker on a public LinkedIn post. We do not use fake demo passwords.

What we are asking

Your eye on what you see — especially colors. If something looks wrong, report it. That helps us repair. We are not asking you to put your name on “Caydra is reliable,” and we are not handing you a secret exam of every lower-certainty pair on day one.

Privacy

We use what you send only to verify that you are a licensed clinician and to communicate with you about access. We do not publish your name, sell your information, or use it in advertising. Full statement: Privacy.

Caydra is assistive clinical decision support for licensed clinicians. It does not diagnose, treat, or prescribe. It is not a substitute for your professional judgment. It is not for patient self-treatment. It is not an FDA-cleared medical device and is not marketed as one. You remain responsible for clinical decisions. Caydra LLC is not your treating clinician.
