I've really liked using onenote, but would like a FOSS alternative if there is one that replicates the experience. I don't need any syncing abilities, since I prefer to store locally.
And if there is a migration tool from onenote to the alternative that would be even better.
@NightOwl As already said, not foss, but obsidian is a really good option. I moved away from Onenot and Notion, and all my files are local in markdown.
