How these alternatives were chosen
Tools Obsidian names as alternatives that this directory also publishes, followed by others in Productivity. The order is not a ranking, and "—" means we have not checked that field — not that the answer is no.
Obsidian also lists Roam Research, Logseq, Evernote, Bear, Dendron as alternatives. Those are not in this directory yet, so there is nothing to compare — and nothing to link to.
