AI Assistant
Unreal Engine 5

Nwiro lives right inside your editor and knows exactly what you're working on. Build worlds, write code, and move faster just by chatting. The plugin is completely free to install, so you only buy credits when you actually need them.

Free to Download

Plugin is free on Fab. Buy credits or subscribe as you grow — pay only for the AI usage you need.

Whatever you're building, there's a tool for it

Wire up a Blueprint. Author a material graph. Retarget an animation. Lay out a level, paint foliage, drive Sequencer, generate with PCG, debug a broken node graph, and then hit Play to let the AI inspect the running game.
