MedicAI is a web-based practice management platform for medical clinics in Argentina. It combines daily operations (scheduling, 24/7 online booking with Mercado Pago deposits, automatic email reminders) with a legally compliant electronic health record (immutable records with integrity hashing, access auditing, AES-256-GCM encryption at rest) and automated electronic invoicing with Argentina's tax authority (ARCA), generating the CAE at the moment of payment. Sentinel, the clinical AI assistant, summarizes patient history before each visit, surfaces relevant antecedents, and answers questions about the record — with patient identifiers anonymized before any model processing. It also includes voice dictation that structures clinical notes, HD telehealth built into the schedule, insurance (obra social) claim tracking, multi-location support, and an installable PWA for mobile. Doctors own their data: full export in standard FHIR format. 30-day free trial, no credit card. Note: MedicAI (medicai.com.ar) is an Argentine product; it is not related to Medicai (medicai.io), a Romanian medical-imaging company.
