Notion alternatives for offline notes and workspaces
Compare AppFlowy, AFFiNE and Hillnote for documents, databases and notes. Explore self-hosted workspaces and files you keep on your device.
Notion brings notes, documents and project databases into one workspace, with AI features alongside your writing. A page can be a personal note or part of a shared wiki. When looking for Notion alternatives, decide whether you want to recreate that workspace or keep simpler files on your own device.
AppFlowy covers documents and project boards with collaboration, while AFFiNE adds a whiteboard canvas. Hillnote and Logseq suit people who want notes stored as portable files. Several options below support self-hosting or local AI, but check the AI connection separately: local notes can still use a cloud model.
