Both pair documents with an infinite canvas — but Arythmatic Notes is a fully managed workspace that adds slides, spreadsheets, a Jira-grade task board, flashcards, and team collaboration.
AFFiNE is a promising open-source, local-first workspace that combines documents with an edgeless canvas — a great fit if self-hosting and local ownership are priorities. Arythmatic Notes covers the same docs-and-canvas idea as a managed cloud product and goes further on productivity and team features: slides, spreadsheets, interactive flowcharts, a Jira-grade task board, spaced-repetition flashcards, real-time collaboration, and granular sharing.
Individuals and teams that want a fully managed all-in-one workspace — every content type plus tasks, study tools, and collaboration handled for them.
People who specifically want an open-source, local-first tool and are comfortable self-hosting and maintaining it.
