Best HIPAA-ready voice AI for medical offices
Tools that will sign a HIPAA business associate agreement (BAA), so the agent can handle patient health information.
| Tool | Price | HIPAA BAA | Best for | |
|---|---|---|---|---|

| Vapi | $0 to start; $0.05/min Vapi hosting, models billed pass-through at cost | HIPAA add-on, $2,000/mo (DPA + BAA) | Developers who want to choose their own LLM, transcriber, voice and telephony provider | Source |
| Lindy | $49.99/user/mo (5,000 credits) | BAA on Enterprise plan | Teams wanting an AI assistant that also handles calls | Source |
| Thoughtly | Not published (sales quote) | HIPAA/BAA on Enterprise plan | Inbound lead teams wanting voice, SMS and email in one plan | Source |
Retell and Vapi are build-your-own platforms, so you or an agency set up the agent. Popular front-desk tools are riskier for patient calls: Smith.ai says it is not HIPAA-compliant and can't handle PHI, Dialzara asks healthcare practices to contact sales for a written regulated-use setup, and My AI Front Desk's own pages disagree on whether it signs BAAs. Get any BAA in writing before patient data touches the line.
