I purchased this tool the first time it came to appsumo. Its nice for saving information like notes, documents, links and more. It has a nice mobile app too. It has A.I. integrated into it and you can use your knowledge base with it in chat. It also provides AI summaries of all your stuff which is great. It would be nice if you could change the view when looking at things to list view like a file folder in windows explorer or like Google drive instead of only the option where it looks like sticky notes. I also would like to see the ability to create collections inside of collections. Also whenever I click collections on mobile it doesnt let me add anything, i have to go to the main menu and click the plus sign to add stuff to the collection. There should be a plus sign inside of collections to add stuff. It would be nice if they created a local app for desktop files. I hope to see even more innovation to the tool in the future and more expansion + integration with ai so that its truly cutting edge. Also increase in pdf size and I haven't tested epub but that as well
