Nexus-3 reasoning engine is live

The Autonomous Engineering Agent.

NexusAI reads your entire repository, plans the architecture, writes production code, generates its own test suite and opens the pull request. You review. It ships.

Immersion Sequence

Every layer of your stack, understood.

Scroll to peel back the surface. NexusAI moves from global reasoning infrastructure, through the humans who build it, down to the machines that ship it — one continuous layer at a time.

Built for engineers who think in systems.

NexusAI is not a browser tab. It's a persistent reasoning agent that lives inside your IDE, terminal and CI pipeline — simulating every change across your dependency graph at machine speed.

Capabilities

Everything an engineer does — executed autonomously.

NexusAI isn't autocomplete. It's a reasoning agent with full-repository awareness, a persistent memory of your conventions, and the authority to open pull requests.

Source code

Autonomous code generation

Describe the outcome in plain English. NexusAI plans the architecture, writes the implementation, wires it into your existing patterns and leaves zero boilerplate behind.

TypeScript Python Go Rust

Repo-wide context

A 2M-token semantic index of your entire monorepo, rebuilt on every commit. NexusAI never guesses your conventions — it reads them.

Loved by engineers who ship for a living.

"We replaced two full sprints of migration work with a single NexusAI prompt. It opened 47 PRs, all of them merged without a single review comment."

FAQ

Questions, answered.

Does NexusAI send my source code to a third party?

No. NexusAI runs on isolated, single-tenant inference clusters and retains zero prompt or completion data by default. Enterprise customers can deploy the entire agent runtime inside their own VPC, so code never leaves your network perimeter.

How large a repository can it index?

The Pro plan comfortably indexes monorepos up to 5 million lines of code with incremental rebuilds on every commit. Beyond that, Enterprise clusters shard the semantic graph across nodes with no practical upper bound.

Can I review changes before they're merged?

Always. NexusAI's default mode opens a pull request with a full rationale, a diff summary and the test results attached. Auto-merge is opt-in and can be scoped to specific paths, labels or authors.

Which languages and frameworks are supported?

First-class support for TypeScript, JavaScript, Python, Go, Rust, Java, Kotlin, Swift, Ruby, PHP, C# and SQL — plus 100+ additional languages through tree-sitter grammars. Framework awareness covers Next.js, React, Vue, Svelte, Django, Rails, Spring and Laravel.

Your next release is already written.

Install NexusAI in under two minutes. Ship your first autonomous pull request before your coffee gets cold.
