Saath (साथ, "together"): your parents' bills and care, handled together.

THE PROBLEM
By 2030, 1 in 6 people in the world will be over 60, and many of their children live in another city or another country. Ageing parents are left handling electricity bills, insurance renewals, bank letters, pension paperwork, doctor visits and medicines on their own. In India, where we're starting, 3 in 10 people over 60 live with none of their children, almost half find tasks like paying bills difficult, and fewer than 4 in 10 can read. Deadlines get missed, penalties get paid, and siblings argue about who was supposed to handle what.

WHAT SAATH DOES
Parents keep using the app they already know: WhatsApp. They send a voice note in Marathi or Hindi, or a photo of a bill. Saath turns it into a task on a shared board for their children, wherever they live, and for the guardian who lives with or near the parent.

- Meta Muse Voice Transcribe turns voice notes into text; Meta Muse Spark reads bill photos and extracts the payee, amount and due date.
- Every extracted field must quote the exact words it came from, and plain code, not the model, checks those quotes against the source.
- If anything doesn't match, the LangGraph agent pauses and asks the family to confirm on WhatsApp instead of guessing.
- The same bill sent twice, even in different languages, becomes one task.
- Siblings and the guardian claim tasks with one tap. Unclaimed tasks near their deadline are escalated, and when a task is done, the parent gets a message in their own language.
- Medicine reminders with one-tap confirmation; if a dose isn't confirmed within two hours, the family is told.
- Health readings by voice, or live heart rate from any Bluetooth watch or strap using the standard heart-rate profile, compared only against limits the family sets.
- Each person chooses English, Marathi or Hindi, and every agent step is written to an audit log.

WHAT SAATH WILL NEVER DO
Move money, interpret lab reports or prescriptions, or act on an unclear document without asking the family.

HOW WE BUILT IT
FastAPI and a LangGraph agent with human-in-the-loop interrupts; Meta Muse Spark and Muse Voice Transcribe through the Meta Model API; the WhatsApp Cloud API with interactive buttons and approved Marathi and English templates; a Telegram bot; a Next.js board with Web Bluetooth; SQLite.

RESULTS
On a held-out set of bills from providers that appear nowhere in our code, Muse Spark extracted the right fields 89.6% of the time, versus 62.5% for keyword rules, and refused every lab report in the test. Model responses are cached in the repository, so the results can be reproduced without an API key.

WHAT'S NEXT
More Indian languages, and more of the paperwork ageing parents face, like pensions and insurance claims.
