Anytype is a Swiss note-taking app for notes, projects and personal knowledge bases. Information is organised as objects rather than plain files, which lets you build templates and structured collections, and templates can be published to a gallery that other users draw on. Apps are available for desktop and mobile.
The project is open source and stores data locally, so you keep control over your material. A Swiss company and a public code base make it a European alternative to American note apps, and it suits people building a knowledge base they expect to keep for years.
Pricing
The free plan includes every feature of the app itself and limits only the cloud side, with 100 MB of sync and 10 shared channels. Paid plans add storage space and remove the limit on shared channels.
