What it does
Mortis Cloud stores Markdown notes with wikilinks, YAML frontmatter, backlinks, graph views, task queries, and offline support. The vendor says sync is end-to-end encrypted and includes 10 GB per account at no charge, with Windows, Linux, Android, and web access. The service says it is funded by donations and does not run ads or trackers.
Mortis Cloud combines a local Markdown notebook with real-time sync and collaborative shared folders. Its notes remain plain files, and the product includes graph, task, calendar, and assistant views inside the workspace. The service is free and provides 10 GB per account; the vendor describes AES-256-GCM encryption and Swiss hosting, but those security claims were not independently audited in this research. Native downloads are listed for Windows, Linux, and Android, with web access for other platforms.
