AFFiNE

AFFiNE is an open-source, local-first workspace that merges documents, databases and an infinite whiteboard canvas into a single tool. In plain terms, it is like having Notion-style docs and a Miro-style whiteboard fused together, where the same content can live as a structured document and on an "edgeless" canvas. This lets you write clean, structured pages and also think visually in space — sketching ideas on a canvas, then organizing them into a document — without copying between separate apps.

Its appeal is the fusion of two modes that are usually separate, plus open-source, local-first ownership. Most tools force you to choose between structured writing and free-form visual thinking; AFFiNE lets you move fluidly between them with connected content, which is genuinely novel for planning, brainstorming and connecting ideas. Because it is local-first, your data lives on your device and works offline, and because it is open source, you can trust it, self-host it and avoid lock-in. For people who think both in words and in space, that combination is refreshingly different.

AFFiNE is a great fit for visual thinkers and planners who want structured docs and a whiteboard in one place, and for those who value open source, local-first design and data ownership. It is younger and less polished than established tools, so it suits the curious more than those needing maximum refinement and seamless collaboration today. It sits alongside Notion and Anytype in the workspace space, distinguished by its docs-and-canvas idea. If that vision resonates, AFFiNE is well worth discovering and watching as it matures.
