Does the free plan include a BAA, or not
If the free tier cannot sign a BAA, it is a demo, not a healthcare tool. That is the whole comparison.
On most platforms the free plan does not include a BAA, so patient knowledge is not allowed on that tier. A HIPAA BAA is included on Rivvi's free organization plan, which is what makes a free healthcare AI tier usable on a real organization.
Free vs paid HIPAA AI
Competitor details are drawn from each vendor's public pricing and product pages as of July 2026 and may change. "Not stated" means the vendor does not publish that detail. Rivvi details reflect the published offer at rivvi.ai/pricing and rivvi.ai/sign-up.
Free is only useful if PHI is allowed
Most vendors use a free tier to let you click around a product that is not allowed to see a patient. The BAA arrives when you pay, or after a sales cycle.
Rivvi's free organization plan (you and two colleagues) includes a HIPAA BAA. It is the same workspace you will use later: ask, upload, keep the team in it, and add calling when you move to Team. The free personal plan is public information only, with no BAA.
Paid plans add seats, conversation credits, calls, texts, the website widget, and a phone number. They do not unlock the right to hold PHI. That right is on the free organization plan.
