Nexa

An autonomous AI research and build platform that runs smart agents, streams results in real time, scores confidence, and helps users turn ideas into working solutions faster.

Inspiration

As developers and students, we often spend a lot of time switching between tools to research ideas, generate code, validate solutions, and track progress. This process is slow, fragmented, and inefficient.

We were inspired to build Nexa to create a single intelligent workspace where autonomous AI agents can research, build, and analyze projects in real time. Our goal was to help innovators turn ideas into working solutions faster and with more confidence.

The Gemini 3 Hackathon gave us the perfect opportunity to explore how advanced AI models can be orchestrated into a collaborative, self-improving system.

What It Does

Nexa is an autonomous research and build platform powered by multi-agent AI.

Users can create projects, define goals, and let intelligent agents handle tasks such as:

  • Researching topics and gathering insights
  • Generating and refining code
  • Producing structured reports
  • Streaming results live to the user
  • Scoring confidence and providing self-reflection
  • Tracking analytics and project performance

All outputs are delivered in real time through a responsive web interface.

How We Built It

Nexa was built using a modern full-stack architecture:

  • The frontend is developed with Next.js and Tailwind CSS for fast, responsive user experience.
  • The backend uses Node.js with an agent orchestration system.
  • MongoDB Atlas stores user data, projects, and analytics.
  • Server-Sent Events (SSE) enable real-time streaming of agent outputs.
  • Google Gemini APIs power research, reasoning, code generation, and multimodal capabilities.

Each AI agent is assigned a specialized role and model, enabling parallel execution and efficient collaboration.

Challenges We Faced

One major challenge was designing a reliable multi-agent orchestration system that could manage parallel tasks while maintaining consistency.

Streaming real-time outputs without performance issues also required careful handling of connections and database updates.

Another challenge was designing meaningful confidence scoring and self-reflection mechanisms that help users trust and evaluate AI outputs.

We overcame these challenges through modular architecture, structured JSON contracts, and continuous testing.

What We Learned

Through this project, we learned:

  • How to design scalable agent-based systems
  • How to integrate Gemini models effectively
  • How to manage real-time data streaming
  • How to optimize full-stack performance
  • How to build user-centered AI platforms

We also gained deeper insight into building transparent and trustworthy AI systems.

Impact

Nexa empowers developers, researchers, and innovators to work faster and smarter.

By automating research and development workflows, Nexa reduces repetitive work and allows users to focus on creativity and problem-solving.

We believe Nexa can improve productivity in education, startups, research, and software development.

Future Plans

In the future, we plan to:

  • Add collaborative team workspaces
  • Integrate voice and video agents
  • Expand analytics and benchmarking
  • Enable plugin-based agent extensions
  • Support enterprise-scale deployments

Our vision is to make Nexa a universal autonomous workspace for intelligent creation.
