Outstanding personal knowledge management application. I've been using this app for years and deeply appreciate how easy it is to use. It integrates my laptop, phone, and e-readers (Kobo, Boox, Kindle, etc ) seamlessly, and collects RSS feeds I have selected. I can construct themed collections and share them as I desire. The program allows for verbose custom tagging, annotation, search, and for those who like that sort of thing, LLM ( AI ) integrations. I highly recommend this app.
