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.

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.

Developer Response ,

I'm sorry about your experience. This is not typical and shouldn't have happened. It appears you were trying to upload files with thousands of pages in a single file. While Chunk can handle entire novels (hundreds of pages), documents with over 500 pages may have some performance issues. Particularly documents with thousands of pages. For better performance perhaps break the document into smaller parts and use the same tag for each while using the 'Large' Chunk size. Hopefully this fixes your issues, and sorry about any confusion or misunderstandings.

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.
