“Aap akeli nahin hain.” — You are not alone.

A voice-based AI health companion for South Asian women navigating perimenopause — built in Telugu, Urdu, and English, because health information should exist in the languages women actually speak.

Live at Mythri — AAsum Nari Voice Companion


The Problem

Perimenopause affects every woman. But for millions of South Asian women, it happens in silence.

AAsum Nari exists to close that gap.


Meet Mythri

Mythri (మైత్రి) means friendship. She is the voice companion inside AAsum Nari.

A woman taps the flower, speaks in her language, and Mythri responds — warm, spoken, culturally informed, and free of judgment. Like a knowledgeable friend who happens to know a lot about women’s health.

Mythri follows the Actionable Empathy framework in every response:

  1. Empathy — validate the feeling warmly
  2. Environment — one practical environment tip
  3. Nutrition — one South Asian-grounded nutrition tip
  4. Movement/Breath — one gentle movement or breathing tip
  5. The Science — one warm sentence explaining the biology behind the symptom

What It Does


Mythri’s Brain — Symptom-to-Pillar Matrix

Mythri uses a server-side keyword detection engine to identify which symptom cluster the user is describing before calling Gemini. Each cluster maps to specific, hard-coded tips — eliminating generic responses and hallucination risk.

Cluster Symptoms Detected Example Tips
Vasomotor Hot flashes, night sweats, flushing, heat Cooling breath (Sitali), cotton layers, avoid spicy masalas
Metabolic Fatigue, brain fog, weight, memory, focus Lentils & chickpeas, resistance training, healthy snacks
Skeletal Joint pain, bone ache, stiffness, back/knee Sesame & almonds, 1200mg calcium, quadriceps exercises
Emotional Mood, anxiety, sleep, insomnia, stress Box breathing (4-4-4-4), omega-3 seeds, sleep hygiene
Urogenital Irregular periods, bleeding, vaginal dryness Iron-rich foods, pelvic tilts, safety kit

Keyword detection works across English, Telugu script, and Urdu script. The why field in each cluster gives Mythri the biological explanation (e.g. “Estrogen affects the brain’s thermostat”) to explain in simple, warm language.


Who It’s For

South Asian women aged 35–55, primarily in India and the diaspora, who are experiencing perimenopause symptoms and have nowhere to turn for information in their own language.

Architecture

Web Speech API (browser VAD — 3s silence threshold)
    ↓
Vercel proxy (api/chat.js) — immediate "received" log to Axiom

Transcript normalization — strips Android STT duplicates

Axiom finally log — fires even on timeout or crash

The frontend and backend are intentionally separated — the Vercel proxy protects all API keys and handles CORS for both aasumnari.com and rekhaaasum.github.io.


Axiom Log Schema

Every conversation turn logs two entries — an immediate received log on arrival, and a success/error log in the finally block. This ensures India sessions are captured even if the function times out.

Stability & Resilience (v15)


Why I Built This

I run community health programs for South Asian women. Again and again, I saw women who had been suffering for years without knowing what was happening to their bodies. Perimenopause is not taught, not discussed, not named.

Mythri is the scalable version of what I do in person — reaching women I can’t reach through library talks or panels. One conversation at a time, in their language.


What’s Next


About the Builder

Built by Rekha — a South Asian woman, community health advocate, and AI product builder with 18+ years of enterprise technology experience across fintech, insurance, and healthcare IT. This project sits at the intersection of two things that matter: closing health equity gaps for South Asian women, and building AI tools that solve real problems for real people.

This is not a portfolio piece. It’s a mission that needed a product.
