Notion's flexibility is real and, for teams, close to unmatched. Wikis, roadmaps, databases with relations and views: if a group of people needs a shared structure, Notion can hold it, in a browser everyone already has. Nobody outgrows Notion because it lacks power. The people who drift away from it for personal notes usually drift for the opposite reason.
At personal scale, the workspace becomes the work. You design the dashboard, define the databases, pick the properties, and then maintain all of it, because a structure nobody tends slides into an inbox page with two hundred unsorted entries. Saving one interesting link means choosing where it goes first. For a team, that overhead is shared and worth it. For one person, it is a quiet tax on every thought.
Mindly is what personal notes look like with the overhead removed. ⌘M captures notes, links, PDFs, files, screenshots, and voice, and AI tags, summarizes, and connects every save on its own; there is no workspace to design and nothing to maintain. The library lives in a folder on your Mac rather than in a browser tab, and semantic search finds things by meaning, not by which database you filed them in.
