HackSignal
Gemini 3 Singapore HackathonA database tool for hackathon participants seeking inspiration on how winning teams use sponsor APIs. Features a sidebar listing hackathons (discovered via web search agents), with drill-down views showing teams per hackathon -- winners are highlighted. Insight agents analyze overall sponsor API usage patterns across each hackathon and surface interesting projects. Each project includes an API analysis agent that describes how sponsor APIs are specifically used within that team's submission, catching non-obvious integrations. Web search agents can find new hackathons, import team project description URLs, or accept pasted descriptions for a summary agent to generate project cards. All agent-proposed updates go through human-in-the-loop approval, letting users accept or decline changes before they're applied.
