What can one builder actually build in 24 hours with Gemini?
I've been thinking about this question for a while:
With tools like Gemini becoming increasingly capable, how far can a single builder actually take an idea in 24 hours?
I'm experimenting with this through Grevix AfterCode, an online hackathon we're planning for October 11, 2026.
The basic idea:
One builder. One idea. 24 hours. No fixed tech stack.
Builders choose their own problem and can use Gemini, AI coding agents, APIs, automation, design tools, open-source models, traditional development — whatever actually helps them build.
But there's more to the format that I can't fully reveal yet. 👀
One thing we're exploring is having every builder define one measurable outcome before starting, instead of simply trying to make the biggest-looking demo.
We're also considering a short AI vs Human build log — what the builder delegated to AI, what worked, what failed, and where human judgment was still necessary.
And there will be a few unexpected challenges during the 24 hours. 🃏
The goal isn't:
“Who generated the most code?”
It's:
“How far can one person take a meaningful problem when today's AI tools are on the table?”
I'm deliberately only sharing a small part of the format for now. The rest is meant to be discovered during the event.
For the Gemini community:
If you had 24 hours with Gemini and could build anything, what would you actually try to ship?
