How it works
From idea to compilable Verse in 3 steps.
Pick a template
Start from a battle-tested preset or a blank canvas — whichever fits.
Customize rules
Drag atoms into WHEN / IF / DO blocks. Live preview as you build.
Copy into UEFN
Paste the generated Verse, hit Play. Done.
See it work
One rule. One block of Verse.
Pick a scenario and watch the Verse get generated. The exact same flow happens in the builder — only with more atoms and more rules.

SoundDevice.Play(Agent)Why Verse Builder
Everything you need. Nothing you don't.
Built by creators, for creators — not as a generic code generator.
100% deterministic output
No LLM guesses. Every line is built from typed atoms, validated against the official UEFN device digest. Same rules in, same Verse out — every time.
WHEN / IF / DO visual flow
Build with colored blocks. No syntax to learn, no indentation traps.
UEFN 41.00 pinned
Generated code always matches the current shipping version.
Battle-tested templates
Open a teleporter, shop, kill race, tycoon or HUD preset in one click.
Copy-paste into UEFN
Hit copy, paste into UEFN, press Play. No package, no setup.

Built different
ChatGPT hallucinates Verse. We don't.
LLMs guess API signatures. Verse Builder emits code from verified device definitions — every line is checked against the official UEFN digest.
- Invents events & methods
- Mixes up devices
- Looks fine until it won’t compile
# ChatGPT output (broken) trigger_device.AgentEntersEvent.Subscribe(OnEnter) # trigger_device has no AgentEntersEvent # wrong device — should be volume_device Teleporter.Teleport(Agent) # Teleport() teleports TO the device # should use Activate(Agent) ItemGranter.RevokeItem(Agent) # function doesn't exist
- Atoms tied to real device APIs
- Version-pinned to UEFN 41.00
- Compiles on the first paste
# Verse Builder output (compiles) VolumeDevice.AgentEntersEvent.Subscribe(OnEnter) # correct device and event Teleporter.Activate(Agent) # sends the agent to the target ItemRemover.Remove(Agent) # correct method on the right device
Copilot
An AI copilot that can't hallucinate.
Describe what you want in plain English. The copilot doesn't write Verse — it picks the right verified atoms and drops them into your canvas. You stay in control, the output still compiles on the first paste.
You ask
Copilot picks atoms
Each atom is tied to a real UEFN device. Nothing is invented.
It never writes raw Verse
The copilot only assembles the same typed atoms you would pick by hand — so it cannot invent an event, method or device that does not exist.
Every suggestion is editable
It builds the rule into the canvas, then hands you the controls. Tweak any atom, swap a device, or undo — nothing is locked.
Same deterministic output
Whether you build by hand or with the copilot, the generated Verse is identical and version-pinned. The AI changes the speed, not the guarantee.

FAQ
Frequently asked questions.
No. Verse Builder is designed for UEFN creators who don't write code. You drag visual atoms into WHEN / IF / DO blocks, and we emit clean Verse for you.
Yes — it's 100% free during the beta. We want to find out if you actually need this and whether the interface feels right. No login required, no credit card.
Generated code targets UEFN 41.00 (++Fortnite+Release-41.00-CL-54872343). Every device, event and method comes from the official digest for that version. When Epic ships a new UEFN release, we re-validate every atom against the new digest and re-pin within days — so the generator never silently drifts out of date.
That's the whole point. The generator is deterministic — no LLM guessing — and every atom is checked against the live UEFN digest. If it generates, it compiles.
ChatGPT writes Verse from its training data, which makes up device names, events, and methods that don't exist. Verse Builder only ever emits code from typed atoms tied to real UEFN APIs.
Epic's assistant is great for learning Verse and getting snippets to study. Verse Builder solves a different problem: it generates complete, working systems — shops, quests, tycoon loops — guaranteed to compile, without you reading or debugging a line of code. Many creators use both.
Yes. Everything you build is yours — the rules, the generated Verse, the project. We never claim ownership over your code or your island.
