AI Approach

We build AI that runs operations.
Not AI that chats.

Most AI implementations ask a model to have a conversation. We ask our models to run operations. The AI Admin in LifeChiAI reads a message, classifies intent, queries live databases, applies business rules, executes actions, and closes the loop — in under 90 seconds, without human intervention.

Layer 01

Intent Classification

Claude Haiku 3.5

Fast, cost-efficient. Classifies every incoming WhatsApp message into one of three skill categories in under 3 seconds. This is the triage layer — it decides which agent skill activates.

Layer 02

Execution Engine

Claude Sonnet 4.5

High-quality reasoning with full tool access to live data. Handles complex, context-dependent decisions: which healer to assign, how to interpret an ambiguous request, when to escalate to human.

Layer 03

Safety & Boundaries

Confidence Threshold · 80%

Every agent action carries a confidence score. Below 80%: the AI escalates to a human with full context. It never acts on uncertain input. It never goes silent on an unresolved case.

Architecture Principles

Decisions that compound over time.

01

Multi-Tenant from Day One

Every database document carries a tenantId. Every query filters by tenantId. No tenant can ever access another tenant's data. This is not bolted on — it is the foundation. Built in Phase 1 before any other feature.

02

Privacy as Infrastructure

Patient phone numbers are never shared with practitioners. All communications go through the platform as intermediary. DPDPA 2023 compliance is a design requirement, not a compliance checkbox.

03

Global from Architecture

International phone number normalisation (240+ countries) is built into the core. Currency, payment gateway, and language are configuration values — not code branches. A new country takes configuration, not code.

04

Configuration Over Forks

New professional verticals require a domain configuration JSON file and a knowledge base document. Not a new codebase. Not a new deployment pipeline. The platform expands without multiplication of technical debt.
