AI-powered clinical workflow platform for Indian hospitals.
Voxa replaces paper-based ward documentation with a unified digital system across all hospital roles — consultants, residents, interns, nurses, pharmacy, and lab — with real-time sync, AI-assisted form filling, and agentic department dispatch.
Built by NeuraData.
A doctor speaks or writes during a consultation. Voxa transcribes and extracts structured clinical data, auto-fills the relevant forms (consent, discharge, pharmacy prescription, investigation orders), and dispatches requests to the appropriate departments — all in one workflow. Every role in the hospital sees their relevant updates in real time.
- OPD & IPD workflows — dynamic forms per patient type and specialty
- Voice-to-form — Sarvam AI transcribes Indian-language speech, Gemini structures it into form fields
- AI-assisted forms — auto-fills consent, discharge, pharmacy, and nursing documentation
- Nurse integration — treatment chart, medication administration record (MAR), vitals charting with threshold alerts
- Agentic dispatch — approved orders fan out concurrently to pharmacy, lab, and nursing APIs
- Real-time sync — SSE for real-time updates across web portals and mobile applications; all roles see updates within 2 seconds
- ABHA integration — fetches or creates Ayushman Bharat Health Accounts; falls back to internal UUID on API timeout
- Offline-first mobile — SQLite store-and-forward for ward connectivity drops
- Multi-tenant — per-hospital tenancy with RBAC across consultant, resident, intern, nurse, pharmacy, and lab roles

AI pipeline (per consultation):
Audio (Opus) → OVH Object Storage
↓
[TranscriptionJob] → Sarvam AI (primary) / faster-whisper (fallback)
↓
[FormExtractionJob] → Gemini 2.5 Flash (structured JSON output)
↓
Doctor reviews pre-filled form → Approves
↓
[AgentDispatchJob] → concurrent department API calls (errgroup)
↓
SSE → department dashboards update in real time

Domain-first layout — all code for a clinical domain lives together, not split across layers.

Each domain package contains: entity.go, repository.go (interface), service.go (interface), handler.go, worker.go, and a postgres/ subdirectory with the pgx implementation. No domain imports another domain directly.
