Ratings and Reviews
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.
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.
Amazing
I started using this app for grad school and it has seriously changed how I study. I have ADHD and usually get overwhelmed trying to keep track of everything I read, especially for technical subjects. Chunk helps me slow down and actually think through what I am reading. It lets me focus on the important stuff without getting distracted or lost. It feels like it was made by someone who actually gets how hard reading can be when your brain is bouncing all over the place. I use it pretty much every day now. It is simple, clean, and really useful. If you do a lot of reading or research and struggle to stay organized or focused, this is worth trying.
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.
Developer Response ,
Thank you for trying out Chunk. We'd love to help you with your issue. There could be a few reasons you maybe having issues get answers returned about your stored notes or documents. Making sure your query contains keywords/phrases in the documents you're referring to. Adding tags to documents would help narrow down the search if you've uploaded large amounts of documents. Please refer to our tutorial videos at https://www.chunkapp.com/tutorials or email us at info@chunkapp.com and our support team will help you directly. Thank you again for your honest review and hopefully we can get you using Chunk as you seem to like the premise. Cheers!
