Subul AI: a clinic's AI receptionist on WhatsApp
Subul AI answers every patient on WhatsApp in under 4 seconds, around the clock, and acts directly in the clinic's hospital information system (HIS): it books, reschedules, cancels, and registers patients. I have led engineering as CTO since May 2026, from the first architecture decisions to the first live clinics.
01The problem
Clinics in the region run on WhatsApp. Patients message to book, move, or cancel appointments, and a receptionist answers between phone calls and the front desk. Messages get missed, replies come hours later, and every booking is retyped by hand into the HIS. Generic chatbots do not fix this because they can only talk; they cannot act in the clinic's own system.
02What I built
The core is an AI agent that understands Arabic and English, in the dialect the clinic chooses, and executes real actions in the HIS through an integration layer that works with whatever system the clinic runs. Around it sits the WhatsApp Business Platform integration on the Meta Cloud API, with coexistence so the clinic keeps the WhatsApp app on the same number. I took Subul AI through Meta's review to secure official Meta Tech Provider status. HIS events flow back the other way as confirmations, reminders, cancellations, and arrival alerts. The team signs into one workspace: a shared inbox where humans can take over any chat with full context, plus tickets, campaigns, customer profiles, a knowledge base, and analytics. Each message is routed to the most efficient model for the job to keep AI cost low, and the platform ships with encrypted messaging, role based access, and full audit logs. I also designed and built the bilingual subul.ai landing page, including the live recreation of the workspace that visitors can try.
03Where it stands
Subul AI is live with its first clinics, from physiotherapy practices to robotic rehabilitation centers, replying in under 4 seconds with zero missed messages. Setup for a new clinic takes days: we handle WhatsApp onboarding and the HIS connection with the clinic's team. The platform is aligned with HIPAA and GDPR.
