TL;DR

Everyone wants to build AI agents. But doing it right is still way too hard.

You can build a website with natural language in tools like Lovable. But if you want to build AI agents, you're stuck dragging blocks or writing code.

Nuvi is the AI agent builder for Software 3.0: Write specs in plain English. Get testable, verifiable behavior — out of the box.

❌ The Problem

Building AI agents still means building behavior manually — whether you’re writing code, dragging blocks, or tweaking prompts.

• Tools like n8n let you create agents without code, but you’re still wiring up logic step by step.
• Tools like Cursor help you code faster, but you still need to know what code to write.

At the same time, tools like Lovable have shown what’s possible with natural language — you can build and launch a polished UI in minutes.

Karpathy called it years ago: “English is the hottest new programming language.” But while we’ve embraced it for websites and weekend projects, there’s still no reliable Lovable for building AI agents.

Intelligent software still lacks a way to go from natural language to tested, trusted behavior.

We need a system where intent becomes implementation — with structure, simulation, and shared understanding built in.

🎯 The Solution: Nuvi

Nuvi lets anyone define, build, and deploy intelligent agents using natural language — with the structure and guarantees of real software development.

What makes us different:

🧠 All in Natural Language

If you can explain what you want, Nuvi helps you build it. No coding, no frameworks, no LLM know-how required.

🤝 Built for Collaboration

Specifications are readable, editable, and versioned — so people across different teams stay aligned.

🧪 Fully Tested by Default

User stories become behavioral tests. You can simulate how your agent behaves before launch — and continuously validate after. Using only language.

⚙️ One-Click Deployment

Click to deploy. Built-in access control and integrations mean you go from idea to agent in minutes.

✅ Nuvi Agents at Work

Agents built with Nuvi are already transforming how real work gets done — here are a few examples:

• A legal SaaS company built a custom BDR agent that scans hundreds of court filings daily, flags high-complexity cases, and drafts tailored outreach directly in HubSpot.
• A mortgage brokerage built a fulfillment agent that processes messy loan documents, checks them against underwriting rules, and saves hours of manual review on every application.
• An international nonprofit built an AI coach that interviews underserved small business owners, generates detailed financial forecasts, and dramatically scales personalized support.

💡Our Secret sauce: Specification-as-Source

In his recent AI Startup School keynote, Andrej Karpathy revamped the idea of Software 3.0 — where we write software using English instead of code.

But English alone isn’t a programming language. If it were, we wouldn’t have invented C or Python. For English to work as code, it needs structure (but we can now relax how much structure we need). That’s what Nuvi provides.

🧠 1. AI Specification Assistant

Describe the agent in plain English. Nuvi helps you clarify goals, cover edge cases, and remove ambiguity — like a linter for intent.

🧾 2. Specification-as-Source

The spec is the agent’s source code. It’s structured, complete, and readable by both humans and machines.

⚙️ 3. One-Click Agent Compilation

We compile your spec into a live agent. Just like devs once implemented PRDs — but this time, the AI does it.

🧪 4. Simulation & Continuous Testing

User stories become test cases. You can simulate the agent’s behavior before launch — and verify it keeps working after.

Nuvi is the behavioral compiler for Software 3.0. Not another prompt wrapper. Not another no-code toy. Real behavior. From real specs. Written in plain English.
