Love the docs-and-canvas idea of AFFiNE but want a hosted workspace with a Jira-grade task board, spaced-repetition flashcards, real-time collaboration, and team sharing handled for you? That is Arythmatic Notes.
AFFiNE is a promising open-source, local-first workspace that pairs documents with an edgeless canvas. If self-hosting and local-first ownership are your priorities, it is a great fit. If you would rather have a fully managed cloud workspace — with collaboration, sharing, AI, a real task board, and study tools all maintained for you — Arythmatic Notes covers the same docs-plus-canvas idea and goes further on team and productivity features.
