I uploaded a copy of the US constitution and the app said it’s a document about AI lol ### 3/5 — My phone model can’t run the app but they let me buy it… *2024-02-19* Hopefully they’ll refund my $2 😒 ### 2/5 — Used to work, now broken and needs an update *2024-02-17* This app was fine until the new downloadable models were introduced. Then it cut the baseline model down to something really small and the larger models refuse to download. ### 4/5 — Neat *2024-01-31* Cool ### 3/5 — Cool idea super slow *2024-01-08* I have an iPhone 14 Pro and it runs so slow it is not usable. Love the idea and the work that has gone into the app but it is not yet ready for prime time. ## Most critical reviews (10 lowest-rated) ### 1/5 — No support *2024-09-29* The models can’t be downloaded and the link for the site are broken. Would love contact from the developer. ### 1/5 — No longer updated *2024-07-26* Development has stopped progress. It was getting twice a month updates and is now a defunct app. ### 1/5 — The app is broken and dev site is down *2024-06-08* Do not buy this app. It’s a rug pull. ### 1/5 — Horrible first impression *2024-01-09* Super slow, crashes and I don’t think it should cost any money. Still very raw to use. Refund please **Developer response:** Now we have a new, lighter weight model that is fast and will not crash on older devices. ### 1/5 — Not working *2024-01-09* The app is not working on my iPhone 13 Pro Max **Developer response:** Now we have a new, lighter weight model that works on iPhone 13s. ### 1/5 — RAM Error on iphone 12 Mini *2024-01-09* Hello, after purchasing the app, I'm unable to open it on my iPhone 12 mini. It displays 'Sorry, your device doesn't have enough RAM. Running the model requires 3814.7MB.' Why was I able to download it from the App Store? How can I request a refund? :) **Developer response:** Now we have a new, lighter weight model that works on your iPhone 12 mini. ### 1/5 — Don’t spend MONEY! *2024-01-09* Keeps telling me I can’t have what I want! I thought I can ask and do whatever.. Terrible service and product! **Developer response:** What question did you ask? Can you provide an example? This language model here is censored. ### 1/5 — No chat history, overheating *2024-01-09* Please fix it **Developer response:** Now there is chat history. And we have a new, lighter weight model that would not over-tax your phone. ### 2/5 — Stop trying to outsmart AI *2024-05-09* Oh where to start with the AI hype cycle here. RAG integration is great in theory but seems poorly implemented. The big problem with this and other LLM middleware is inserting system instructions that are not documented and can’t be edited: “I'm here to help answer questions and provide information to the best of my ability. My system instructions are to always assist with care, respect, and truth. I will respond with utmost utility while ensuring that the information provided is secure and accurate. I will avoid harmful, unethical, prejudiced, or negative content and instead promote fairness and positivity in all of my responses.” Positivity? Truth? The truth is that’s short-sighted censorship and a fail in my book. ### 2/5 — Disappointed. *2024-04-24* Although this is a good app and you guys did your thing, I only realized afterwards that this isn’t what I was looking for, it’s missing many features I was hoping for but that’s my fault. Do keep up the good work, I’m sure there are many updates to come but as of now I can’t make any use for this app. ## Most praised reviews (10 highest-rated) ### 5/5 — Astonishingly great! *2024-04-06* Excellent AI. Almost as good as Google Gemini. For offline use, this is amazingly fantastic! Wish the info was updated past 2021, though. Well worth the price. Thank you Developer! High Five! ### 5/5 — Ai dev review *2024-03-19* As a local app hosted on a mobile device this app presents outstanding performance. The results are very impressive and useful for summarizing and explaining large amounts of data and code. Good job 🤘🏻 ### 5/5 — Really Impressed *2024-03-12* I’m researching for a solution to a service we need and this is checking a lot of boxes for what I wanted to see in a locally installed model on my phone. ### 5/5 — Brilliant app - runs smooth *2024-02-04* Brilliant app. 🧠This is an incredible tool that will allow for use without concerns of privacy leaks. I use it for my small business with less concern of GPT eventually selling or leaking company details. Highly recommend offline chat. 🔥🔥🔥 ### 5/5 — Works well on the iPhone 15 Pro *2024-01-15* I recently upgraded from an iPhone X to the 15 Pro and this is one amazing app. It compares favorably with ChatGPT, based on about 30 prompts. I wish it could save my prompts and their answers - but it’s not a big deal. To have something this powerful in my pocket is amazing. I can’t find a developer support email, but it’s probably hiding in plain sight. Definitely worth getting if you have an iPhone 15 Pro. ### 5/5 — Works as advertised *2024-01-14* Great initial effort. Looking forward to future updates. ### 5/5 — Works great! *2024-01-08* So cool to run an LLM on your iPhone with no internet connection. I flipped on airplane mode and used it on iPhone 15 pro max. It’s fast for something running local. Device gets a bit warm, but otherwise great ### 5/5 — Keep up the great job *2023-12-25* I see a lot of potential with this app. It’s not perfect, but I am confident the developer will continue making this a great tool to allow offline chat abilities. I have tried getting local install with some of the AI Chat options, like gpt4all, serge, llama. It is so slow on my older laptop. It is amazing what the developer has done to have this functionality on my ipad. Keep up the great work ### 4/5 — Almost there *2024-03-16* Really clean interface. Running Mistral 7B on device is awesome. Though, I’d love to see an option to customize the system prompt, at least. ### 4/5 — Downloading other models not working *2024-02-12* Tried to contact the dev but the support link on the app page leads to a site that doesn’t work. Have tried multiple times to download the small (Mistral 7B) model which when opening the app I was notified my phone (iPhone 13 Pro) can support and should have more parameters and give more complex answers. The download completes but as soon as I close the model settings page, the download is deleted and the Small model is still greyed out. I have a 1TB model with 700 GB free space available. Assume this is just a bug so just making the dev aware. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
