How is NeoStack different from AI coding assistants like Cursor or GitHub Copilot?

Code assistants stop at source files. NeoStack is an AI copilot for the Unreal Editor itself: it creates and edits Blueprints, materials, and levels as real engine objects, in the live viewport. You can even connect those same coding agents — Claude Code, Codex, Copilot — and let them work inside the editor through NeoStack.

What can the agent actually change in my project?

It works across the engine — Blueprints, materials, levels, and code — through a guarded tool pipeline rather than by pasting text at you. Every edit is journaled and reviewable.

Does my computer need to stay on?

Yes. The agent runs on your machine because that is where your project and engine are. Web and mobile reach that live session rather than moving it to a server.

What can I actually do from my phone?

Read the transcript, send an instruction, cancel a turn, approve or deny a permission request, and pause a running goal. A notification tells you when it needs a decision.

How should I read the benchmark?

As directional evidence from a controlled five-task pilot, not a statistically powered market ranking. Every arm used Unreal Engine 5.8, the same model configuration, fixed limits, raw logs, and an independent verifier.

NewNeoStack wins the UE 5.8 agent benchmark

Your Unreal Engine AI agent, everywhere you work.

An agent that lives inside the Unreal Editor and actually knows the engine — Blueprints, materials, levels. Start it at your desk, watch it from the web, approve what it asks from your phone.

It knows Unreal. Blueprints, materials, levels — real engine edits through a guarded tool pipeline, not a chat window guessing at your project.

You are never tethered. Start a session at your desk and pick it up on the web or your phone. Close the laptop; the work keeps going.

One seat, every surface. Editor plugin, desktop app, web, and mobile in one place — not four separate products.

UE 5.8 benchmark

More finished. Less back-and-forth.

Five products ran five identical Unreal tasks under the same limits. NeoStack completed the most work with the fewest requests.

NeoStack led all three measures in the July 2026 pilot.

How it works

Running in minutes

Install the plugin, describe a change, and keep an eye on it from whatever screen you happen to have.

Install. Add the plugin to your Unreal project, or open the desktop app. Sign in once and your devices find each other.

Ask. Describe the change in plain language. The agent works in the live editor and asks before anything it cannot undo.

Walk away. Follow it from the web or your phone. Approve what it needs, and it carries on without you at the desk.
