easy to use and i love to work with the plugin and claude code.
The AI is integrated well and works well and easily. The whole workflow is good, and it seems to be supported well by bug reports etc.
This is the parfect thing i have wanted for a while. this is very useful and works fine for me
Tool works great, has its bugs but you can easily report it in their discord & they will work with you as well as give you detailed updates!
Fantastic tool if you're spending a lot of time inside Unreal. The AI integration feels natural, and being able to generate environments, Blueprints, and C++ without leaving the editor is a real productivity boost. The developers also seem to be updating it frequently, which is always a good sign.
I own this nwiro pro with a humble bundle. Does Good job! I am Happy!
I've tried several AI tools for Unreal, and this is one of the most promising ones so far. The world-building features are especially impressive, and the workflow keeps getting better with each update. Looking forward to seeing where the roadmap goes.
A great and pleasant assistant when working with Unreal Engine 5 :-)
Landscape tool is unbelievable. I can not wait to see more.
Great job! Your work is truly exceptional and has been a huge help with my project. I look forward to your future updates
Very nicely done the best or one of the best ever made ! Complex, professional yet simply easy to learn and master ! You are like the Cake Boss tv show Buddy Valastro's cakes bakery and we're the fat kids enjoying all that candy yeap !
NWIRO AI Pro has become an essential tool in my Unreal Engine workflow. The World Builder feature is outstanding, it allows me to generate massive, detailed environments and complex scenes in just minutes using simple prompts. The AI Agents are surprisingly intelligent, helping with everything from blueprint logic to asset management and optimization. Integration with UE is smooth and stable, with powerful tools and plugins that actually deliver on their promises. Whether I'm building open-world projects or iterating on smaller levels, the time saved is massive. Prompt responses are high quality and creative, though there's still room for even better fine-tuning options in future updates. Overall, this is one of the best AI tools I've used for game development. Perfect for both beginners looking to speed up their learning and professionals who need to work faster. Highly recommended!
Nwiro AI Pro is an impressive addition to Unreal Engine. Having AI available directly inside the editor makes experimentation and iteration much faster. The plugin provides a solid collection of Unreal-specific tools instead of just being a generic AI chat interface, which makes it genuinely useful for daily development. I also like that it supports both cloud and local AI models, giving developers flexibility depending on their workflow. Great work by the team, and I'm excited to see how the project evolves.

Interesting to see how local hosting goes as I refuse to spend money on tokens..
First off, with the limited test credits, there is only so much you can test, and since I am not currently in production, I am not buying additional credits yet. Having said that, I have noticed that some prompts work better than others. Iterating is effective, but does cost extra credits. I would not yet trust it to make complete environments, but it does greatly help with environment work on a smaller scale. I can definitely see this as a future tool in my toolchain, and am expecting that it will only improve. (EDIT: Either they improved it, or I am getting better at using it!)
It was very good at analysis. It found errors I couldn't locate, and I solved a problem in an hour that I hadn't been able to solve for a month. It also helped with many other things. Personally, I just use it for analysis and do the coding myself. It's quite successful. It responds quickly, analyzes quickly, processes tasks fast, and does everything thoroughly. It's a fantastic plugin, and I hope it becomes even more successful in the future.
I've slowly started to add AI scripting/code into my workflows to help with manual/repetitive tasks, or even complex setups that I barely know how to do. This tool is beneficial in such scenarios!

As someone with very little knownledge of UE as hobbiest, this tool is helping me out quiet a bit ! Let's hope they keep developing and updating as time goes by
amazing plugging and hope they stay updating it!!!
At first, I was honestly a bit skeptical. Still, I decided to go straight for the PRO version of NWIRO AI without even testing the free version beforehand. Looking back now, I can confidently say: absolutely worth it. I'm genuinely impressed with the tool. Even if you don't specifically need complex environments or blueprints, you can still ask general questions and receive very helpful answers along with proper instructions on how to do things correctly. It saves a surprising amount of time. Humanity really reached the point where we pay AI to explain other tools to us. Somehow depressing, somehow beautiful. Another big plus is the support team. They respond quickly and are very helpful. As expected from Leartes Studio, the quality speaks for itself once again. If you're looking for something that can simplify your workflow and take a lot of work off your shoulders, this is definitely the right choice. I'm already excited for the upcoming features Leartes Studio will release in the future. I don't regret buying the PRO version for even a second! :)))
I have only just started development for my first game and this tool is simply amazing for beginners, it help me a lot with my world building and i have only scratched the surface of what this tool can do. I cant wait to see how they continue to develop this tool and make it even better.
Super cool btw thanks for this. also i think its cool that we can use ai for this stuff but i dont think it should replace are job.

The AI understands the prompt and builds the exact environment I have in mind. It's really great.
Found out about this through Emre Yıldırım, and it honestly feels much more polished and user-friendly than its competitors. Being able to connect our own AI tools is a fantastic feature, but their built-in AI seems quite powerful as well. If my project scales up, there's a very high chance I'll switch to using their native model.
This is a life changing tool. Very helpful to be able to plug in different API's. I can wait to see this tool at its max potential.
The plugin is fun to use. I tried it with some trial and error and was able to achieve what I want, but still you need to tweak things to your own desire to get the right result. The Discord Support is very responsive. I have reached out to them multiple times and they help me all the time with my inquiries.
hello everyone.in new to unreal engine, I've been playing a lot of games, and always wanted to make my own, but never had the nerves, to sit and learn hours of coding just to make a simple pixeld animation, and now the technology got so advanced I can make a high quality AA or AAA game with my few friends. thank you for this opportunity guys. i didn't even used it yet but if I can connect Claude agent to it it is already awesome I rate this 7🌟 out of 5🌟
Nwiro surprised me in a very positive way. I spent several hours testing it, mainly for environment and landscape generation workflows, and the tool significantly speeds up the early iteration phase while still producing visually solid results. Especially for larger worldbuilding workflows, this can save a LOT of time. I should also mention that I personally didn't spend much time testing the generative side of things like the meshy 3D generation feature, mainly because I generally prefer modeling assets myself. That said, I can still see those tools being very useful for rapid prototyping and early concept exploration for developers who enjoy that kind of workflow. Overall, I think this is a genuinely useful toolset with a lot of practical value for developers looking to speed up iteration & experimentation inside UE. Based on my experience so far, I would definitely recommend giving it a try, especially for teams or solo devs interested in faster worldbuilding and prototyping workflows.
I'm very skeptical about neural networks. But, surprisingly, the plugin is excellent and allows for significant time savings when working with the engine. Overall, I think it's definitely a must-have at this point.
One of the best AI tool with unreal engine. This is so strong, i reccomand to everyone
I'm not very advanced but can't wait to see how these systems develop
Really interesting tool and one of the more unique AI integrations I've seen for Unreal Engine recently. The workflow feels surprisingly smooth inside the editor, especially for experimenting with environments and quick iteration. I tested some world-building features and it definitely speeds up early production work. The team is also active and helpful in the community/Discord, which makes a big difference for a tool like this that's evolving quickly.
loving how easy this is to use.
Tried and delivery as promised. Well done. Must try for your project
The workflow integration is smooth, the environment generation tools are impressive, and the AI assistant features save a ton of time during development. Easy to use, actively updated, and packed with powerful features for world building and rapid prototyping.
Helpful and practical tool for Unreal Engine. It can save time with workflow questions, Blueprints, and general project setup. It is still evolving, but the idea is strong and it already feels useful for developers who want AI assistance inside their UE workflow.
Easy to use, just type in the prompt, and the job is well done and fast. Props to Leartes team for bringing Nwiro to us. Cheers
Highly recommend. Very useful for game development advanced or beginners
It's great to have AI integration into the editor. So, few companies are doing this and it's key to increasing productivity.
Great AI assistant tool for UE5. It helps speed up the workflow and makes repetitive tasks easier. Very promising plugin with a lot of potential.
Really liking the AI tool. Wish it would be able to do more. I guess people just need to leave reviews to unlock more features.
Finally can make good environments without Learning complex PCG
This is such a gamechanger, especially for indie devs. Its almost impossible to believe that it's real. Set up is incredibly easy and I love that I was able to integrate it with Codex, that's a huge plus, no need to purchase more credits or another subscription. There's a lot of AI tool kits for Unreal Engine popping up now but this one feels the most professionally crafted and has SO many capabilities, it can basically do almost anything. I've integrated this into my project and workflow now and I can't imagine going back.
Nwiro is a really solid plugin for UE5. It takes a lot of the busywork out of setting up Blueprints and other stuff. It's not going to do everything for you, and you'll definitely still need to go in and tweak the results by hand. Still, from here it can only get better.
As a brand new game developer, this tool has been invaluable with being able to iterate and learn quickly. Orders of magnitude faster than I would be moving without it. Now if only they would port something like this over to Unity 😎😎
Top notch UE AI plugin! I'm very impressed how this could speed up your workflow!
Perfect for saving time(a little lazy but helpful). 😊👍
Best software ever. Good publisher. So useful. I recommend to everyone.
Nwiro has become an essential part of my Unreal Engine workflow. The native MCP integration is incredibly smooth — I can use my own Claude or Cursor subscription directly inside the editor without any clunky Python bridges or external tools. What impresses me most: • Extremely fast world building and PCG generation • High-quality Blueprint and C++ code generation • Excellent context understanding of my project. I went from spending hours on repetitive environment work to creating rich, detailed scenes in minutes. The “Bring Your Own AI” approach is a huge advantage, no surprise token bills and I get to use the best models available. Compared to other UE AI tools I’ve tried, Nwiro feels the most native and polished. It’s not just another chat window, it’s a real co-pilot that understands Unreal Engine deeply. If you’re serious about speeding up your development, especially for environment art, level design, or rapid prototyping, Nwiro is a must-have. Highly recommended!
Keep up the interesting work, love to see where it goes!
I mainly tested Nwiro for landscape and environment workflows and was honestly surprised by how fast it speeds up worldbuilding. The generated results looked far better than expected and made iteration much quicker during testing sessions. For prototyping and concept exploration I can absolutely see the value. Definitely a very interesting toolset for developers.
So glad I made this exciting discovery (it was in a email but yeah) 😄
NWiro significantly speeds up the production workflow. It removes the need for manual scene building and intelligently scans existing assets to generate results quickly. The automatic placement and collision prevention features make scene creation clean and consistent. A strong solution for anyone who wants to work faster and more efficiently. Easily deserves 5 stars.
it great, i used it in some samples and it works very well. Keep going!!! Bravo !
I can say that creating biomes are unbelievably easy with this tool. The great thing is that I can create the biomes with my own assets! Btw guide helped me a lot. I can not wait to see upcoming features.
