Pilot Testing of Poshan Didi Chatbot, Madhya Pradesh, India

Pilot Phase	Users, No.	Sample Bias	Engagement
1	10	Users are manually chosen	Medium: WhatsApp. The intervention interaction is manual (users engage with Poshan Didi, but a researcher reads and responds manually to user questions). Evaluation is purely qualitative.
2	100	Users are not representative of the larger population	Medium: Telegram. Intervention is increasingly automated. Results are increasingly quantitative, though not necessarily widely generalized.
