When Mani Devi, an Accredited Social Well being Activist (ASHA) in rural Rajasthan, noticed the underweight toddler, she knew one thing was fallacious—however not how severe it is perhaps, or what recommendation to provide.
So she reached for her cellphone and opened WhatsApp: In Hindi, she typed a query to a brand new software known as ASHABot: What’s the perfect weight for a child this age?
The chatbot—skilled in Hindi, English, and a hybrid often called Hinglish—responded inside seconds: a child that age ought to weigh round 4 to five kilograms. This one weighed much less.
The bot’s reply was clear and particular. It inspired feeding the newborn eight to 10 occasions a day, and it defined counsel the mom with out inflicting alarm.
That, she stated, was one of many many encounters with ASHABot that modified the best way she does her job.
The software is a part of a quiet however important shift in public well being, one which blends cutting-edge synthetic intelligence with on-the-ground realities in a few of India’s most underserved communities.
ASHABot, launched in early 2024, is what occurs when a generative AI mannequin akin to OpenAI’s ChatGPT or GPT-4 will not be solely skilled on the broader web, however is related to a information base containing India’s public well being manuals, immunization pointers, and household planning protocols. It takes voice notes when prompted and gives solutions that assist the ASHAs serve sufferers.
Constructed by the nonprofit Khushi Child (opens in new tab) utilizing know-how developed and open sourced by Microsoft Analysis, the bot has been reworking how a few of the nation’s ASHA staff do their jobs. These ladies are the glue between India’s rural households and the well being system, chargeable for every little thing from vaccination information to childbirth counseling. However they obtain simply 23 days of primary coaching and infrequently work in settings the place medical doctors are distant, supervisors are overburdened, and even cell sign is unreliable.
“ASHAs have at all times been on the entrance traces,” stated Ruchit Nagar, co-founder and CEO of Khushi Child and a Harvard-trained doctor. “However they haven’t at all times had the instruments.”
Nagar’s relationship with ASHAs goes again practically a decade. In 2015, he launched Khushi Child with the aim of digitizing well being information in underserved communities, typically designing tech programs that have been domestically grounded. The concept of ASHABot emerged in late 2023, throughout a summit with stakeholders in Rajasthan.
On the time, Khushi Child was working with Microsoft Analysis on a separate AI undertaking—one which used eye photographs to detect anemia. However the buzz round massive language fashions, particularly ChatGPT, was rising quick. Nagar and his collaborators started to ask whether or not this know-how may assist ASHAs, who typically lacked real-time entry to high quality, comprehensible, medically sound steering.
“ASHAs have been already utilizing WhatsApp and YouTube. We noticed an inflection level, new digital customers prepared for one thing extra,” stated Nagar, now a resident on the Yale Faculty of Medication in New Haven, Conn.
So that they started constructing.
Microsoft researcher Pragnya Ramjee joined the undertaking round that point, leaving a design job at a hedge fund to give attention to know-how with social influence. With a background in human-centered design, she helped lead the qualitative analysis, interviewing ASHAs in Rajasthan alongside a skilled translator.
“It made an enormous distinction that the translator and I have been ladies,” she stated. “The ASHAs felt extra comfy being open with us, particularly about delicate points like contraception or gender-based violence.”

Ramjee and the workforce helped fine-tune the system in collaboration with medical doctors and public well being specialists. The mannequin, primarily based on GPT-4, was skilled to be extremely correct. When it receives a query, it consults a fastidiously curated database—round 40 paperwork from the Indian authorities, UNICEF, and different well being our bodies. If the bot doesn’t discover a clear reply, it doesn’t guess. As a substitute, it forwards the query to a small group of nurses, whose responses are then synthesized by the mannequin and returned to the ASHA inside hours.
The aim, Ramjee stated, is to make sure the bot at all times stays grounded in actuality and in the true coaching ASHAs obtain.
To this point, greater than 24,000 messages have been despatched by the system and 869 ASHAs have been onboarded. Some staff have used it solely a couple of times. Others ship as much as 20 messages in a single day. Matters vary from the anticipated—childhood immunization schedules, breastfeeding finest practices—to the surprising.
“They’re asking about contraception, about youngster marriage, about what to do if there’s a combat within the household,” Ramjee stated. “These aren’t simply medical questions. They’re social questions.”

One girl got here to Mani Devi saying she’d missed her interval for 2 months however wasn’t pregnant. The bot offered Devi with info that gave her the boldness to guarantee the affected person she had nothing to fret about.
The responses are available each textual content and voice be aware, the latter typically performed aloud by ASHAs for the affected person to listen to. In some circumstances, voice responses about long-acting contraception assist persuade hesitant ladies to start remedy.
There is no such thing as a query the know-how works. However the workforce is fast to emphasise that it doesn’t change human information. As a substitute, it amplifies it. ASHABot illustrates how LLM-powered chatbots may help bridge the knowledge hole for folks, notably these with restricted entry to formal coaching and know-how, stated Mohit Jain, principal researcher at Microsoft Analysis India.
“There’s a whole lot of debate about whether or not LLMs are a boon or a bane,” Jain stated. “I consider it’s as much as us to design and deploy them responsibly, in ways in which unlock their potential for actual societal profit. ASHABot is one instance of how that’s potential.”

Throughout a door-to-door go to, an ASHA employee makes use of ASHABot to information a pregnant girl by important info on materials well being and diet.
After all, the chatbot isn’t good. Some customers nonetheless choose to name folks they know, and the massive query of scaling stays. The workforce is exploring personalization choices, multimodal help like picture inputs, and parallel LLM brokers to make sure high quality assurance at scale.
Nonetheless, the imaginative and prescient is expansive. As of now, ASHABot is simply utilized in Udaipur, one of many 50 districts in Rajasthan. The long-term aim is to convey ASHABot to all a million ASHAs throughout the nation, who maintain about 800 to 900 million folks in rural India. The potential ripple impact throughout maternal well being, vaccination, and illness surveillance is immense.
Nagar, who has traveled to India twice yearly for the final 10 years to analysis the wants of ASHAs, stated there are nonetheless “many issues but to discover, and lots of massive inquiries to reply.”
For ASHAs like Mani Devi, the shift is already actual. She says she feels extra knowledgeable, extra assured. She will be able to speak about beforehand taboo topics, as a result of the bot helps her break the silence.
“General, I may give higher info to individuals who need assistance,” she stated. “I can ask it something.”
