Powerful app

This app is seriously slept on. It can handle documents and images. It allows the use of custom .GGUF models and supports MCP tools. It has web search, current time, weather, and location built in and you can add your own MCP servers with an API key or Oauth 2.x. If you have an API key for a cloud model such as Claude or ChatGPT you can import that and use it as well. While it’s not LM Studio it contains nearly everything you could need in a mobile context. You can customize hyperparameters, use KV Cache quantization, and support context lengths to whatever your device capabilities are. You can even adjust the amount of tokens used for image analysis which is super useful. I have been able to run Qwen 3.5 4B (Q5_K_M) with VL projector disabled at 80k context length with Q5_1 KV Cache quantization… on an iPhone 17 Pro. The app only crashes on me if I try to do something insane such as run Qwen 3.5 9B at 48k context. The app works great on Mac as well and it’s intuitive enough that my mom is able to use it. If the app is crashing on you choose a smaller model or upgrade your iPhone 11; it literally came out last decade.

Wow, thank you so much for taking the time to write such a detailed review! It really means a lot, especially because you clearly explored many of the advanced features. My goal from day one has been to make powerful local AI accessible on mobile without sacrificing flexibility, whether that’s running custom GGUF models, connecting MCP servers, or using cloud providers when needed. I also had a good laugh at the iPhone 11 comment 😄. More seriously, you’re absolutely right that model size and context length need to match the device’s available memory. The app tries to expose those settings so advanced users can push their hardware, while still remaining approachable enough for everyone else. Thank you again for your support and for helping others understand what the app can do. Reviews like yours genuinely help independent apps like this one grow.

iOS local performance is unbelievably fast

This thing is sick. As far as I’m aware this is the only local ai sandbox that allows your local model on your phone to access the web through iPhones. Developer please explain agentic shortcuts with better copy. Users that are looking for something like this have no idea its already available because there’s no sales copy explaing

One of the best

BonzAI is one of the best local AI apps I have tested on iPhone so far. For a free app, its local model experience, tool support, and overall direction are genuinely impressive.

Response from developer

Thank you so much for your kind words! I’m really glad to hear you’re enjoying BonzAI and that it stands out among the local AI apps you’ve tried. My goal is to make powerful, private AI accessible to everyone, and it’s incredibly rewarding to hear that the app is heading in the right direction. Thank you for your support, and I hope you’ll continue enjoying the upcoming updates!

Great app for running local AI

I don’t use ai too often but I’m trying to utilize it more on device and this app helps me do that in a quick, accurate and efficient way. The user interface is phenomenal. Very, very underrated app!

Response from developer

Thank you so much. Really happy to hear the app makes on-device AI simple and useful for you. And thanks a lot for the kind words about the UI

The Best.

I have tried countless apps in the app store to find one that lets me use Prism ML’s Bonzai with full web access. Im not sure what sort of dark magic this app is using, but the quality of the web searches and the flawless integration of my beloved Bonzai 8B has currently replaced my entire habit of going to Google for web searches. This has replaced the need for Google web search, GPT for random questions, and sometimes even shopping. The weather and clock features are excellent too. Simply asking my model about my location’s weather gives highly accurate pulls every time (with the right settings and setup of course). As far as integration goes, I have yet to find an app that is compatible with Bonsai (fully) AND uses the correct settings its makers recommended + full web search and much more.

Thank you so much. This means a lot to hear, especially from someone using Bonzai 8B heavily. Really happy the web search integration and built-in tools are working as you expect. More improvements coming soon…

Decent LLM Client

Works fine sometimes, but quite often takes up 100% of the CPU and then I have to kill the session. Please fix this!

iOS app works

I got the iOS version of this app first, and it worked fine with my “custom” endpoint. I use the same endpoint with the macOS version and it doesn’t work. Doesn’t show the models. Doesn’t show any error message. It just… doesn’t… work.

Response from developer

Thanks for your feedback, and sorry for the confusion you experienced. There was indeed an issue affecting the macOS version, and the fix itself was unfortunately delayed due to Apple’s review process. This has now been resolved, and the fix is included in the latest version of the app. Please make sure to update BonzAI on macOS : your custom endpoint and models should work as expected again. If you still run into any issues, feel free to reach out, I’ll be happy to help.

Impressive UX and features

I really like the look and feel of this app. Good selection of models, has conversation history, *shows you which models will run great, good, and just alright on your device*. UX design is very good (a lot of devs miss the importance of this). An option to connect to locally hosted inference servers is all this needs - initially 4 stars on this point, but moved to 5 for the UX.

Response from developer

Thanks so much for your awesome feedback Just a quick heads-up: you can now update the app to enjoy the feature you mentioned 😉 I’ve added support for connecting to locally hosted inference servers. Really appreciate you taking the time to share your thoughts and for bumping the rating to 5 stars for the UX

Censorship

It’s too scared to talk or do pretty much anything that has to do with anything in the news it’s way too controlled and throttle

Response from developer

Thank you for your feedback. The app uses publicly available open-weight models and does not apply additional restrictions or content filtering on top of them. If you experienced limitations around news-related topics, this is likely due to the behavior of the specific model being used rather than intentional throttling within the app itself. Different models can vary significantly in how they handle sensitive or current events topics. You may want to try a different available model to see if it better matches your expectations. If you’d like, feel free to reach out with more details about what you tried. I’m always open to improving the experience.

Stunning work

(My last review was deleted after being commented on for some unknown reason and I use this app daily so I thought I’d just update) after trying this app out for awhile I can safely say it is the most recommended on device ai assistant I’ve found yet gives ACTUAL ACCURATE information with web searches dosent take up too my system power completely on device so no worry about the global impact or data collection 10/10 app only thang id really like too see is a text too speach feature OR voice chat the llms here are so accurate it would work out rather decently
