The results are in! We are thrilled to announce the winners of the Built with Google Gemini: Writing Challenge presented by Major League Hacking (MLH).

Choosing our five winners was no easy task. The submissions we received were candid, thoughtful, and packed with genuine insight. From passion-projects to side-hustles, wild-ideas and thoughtful-tools, we were struck by how openly participants shared both the highlights and the friction points of working with Google Gemini. That kind of honesty is what makes a great reflection post, and you all community delivered.

To everyone who submitted: thank you for taking the time to write it all down. We hope putting it into words was as valuable as the building itself.

Without further delay, here are the winners.

Congratulations To…

@jowi00000 built Plante, an automated greenhouse monitor that leverages the Google Gemini API to power two core features: Context-Aware AI Chat and Weekly Pulse Insights. We loved learning about the hardware components and how the team gamified the frontend experience for users.

@astrodeeptej fused NASA data with Gemini to build "CosmoDex", an interactive dashboard for tracking Near Earth Objects. Google Gemini was utilized to generate dynamic, gamified threat assessments and sci-fi lore, a stellar example of making data engaging and accessible!
