## Chunk Reviews in United States

### **--- "Not finding information within your own documents"
I’m not sure what to truly think about this app. It’s a great concept, allowing you to store your notes and documents within the app. The idea is that you will be able to find specific information by chatting with the built-in AI. In concept, the app is designed to give you information specific to your notes per your request or query while also supplementing it with any relevant information based on its online search. So in concept, you would be able to cheery your notes well being supported by additional online information. But this is where it fails. Anytime I’ve asked for specific information which is very clearly found within the documents I uploaded to the app, it returns a response, stating nothing is found within my notes or documents that matches my query.
-- abeautifulnewworld, 2024-08-06

### ***** "Good support"
Edit 2/22: The developer has been very responsive in trying to resolve the issues. I've also discovered that some of the issues I experienced were related to an ongoing ChatGPT issue with referencing uploaded documents, as I've seen similar errors when interfacing ChatGPT directly.

Original:
I was very drawn in by the description of this app, but I've found that in use it doesn't seem to do what it has promised. It does not pull from any of the documents I've added, and continuously gives me responses telling me that it, in fact, cannot reference uploaded documents. Considering that this seems to be the point of the app, this is super disappointing. Tags are super buggy, and I can only add them using my iPhone, not the Mac or the Vision Pro apps. Not that they seem to do anything. Chats are not persistent if you hit reload, so you just lose everything that's been generated.
-- Panifex, 2024-02-22

### ***** "So helpful!"
I’ve been using the app to organize my class notes and it’s been so helpful! I use the chat feature to give it some basic instructions on what I want and it’s able to take my mess of notes and create outlines that are helping me understand the concepts better. It’s really like having your own assistant! I’m sure I haven’t even realized all the other ways I can use it.
