Nutrition advocate Revant Himatsingka, popularly known as Food Pharmer, has partnered with OpenAI to launch the “Build Karega India Challenge,” inviting participants to build health and wellness app prototypes using ChatGPT Work or Codex.

The challenge calls for simple, responsible app ideas that can help people make better health or wellness decisions. In a video announcing the initiative, Food Pharmer floated possible use cases – an app that scans a photo of a hotel menu and flags the healthier choice, or a platform that helps hospitals connect with neighbourhood blood donors. “We can improve health a lot by using AI,” he said while introducing the challenge.

The challenge’s build guide walks participants from an identified problem to a working prototype or demo that judges can review. It asks entrants to use the ChatGPT desktop app and select Work, then use Codex to publish their app and generate a link for submission. Entries will be assessed on responsible design, safety, and potential social impact.

Selected eligible entries may be featured on Food Pharmer’s channel and receive six months of ChatGPT Pro, with eligible participants also in the running for a prize from OpenAI, subject to official terms and judging criteria.

Submissions close August 27, 2026, at 11:59 PM, with selected entries to be announced later. “If your app can help even one person make a healthier choice, it is worth building,” the announcement said – under the tagline “Let’s Make India Healthy Again.”
