📝MythOS describes itself as a networked knowledge platform where every idea, person, project and decision lives as a linked memo in a library you own. 📝Anytype's official repository calls it a "Local‑first, peer‑to‑peer & end‑to‑end‑encrypted knowledge OS for macOS, Windows & Linux." They split on where the work begins: Anytype's documentation says "Everything you create lives on your device first, not on a corporate server," while MythOS memos can be published, shared and handed to AI agents over 📝MCP through one endpoint.
At a Glance
Storage and Privacy
Anytype's documentation names three differentiators: 📝Local-First, End-to-End Encryption and No Lock-In. Under encryption it states, "Nobody, not even the team at Anytype, can see what you're working on." The README adds "Offline‑first, local storage with optional peer‑to‑peer sync," and its collaboration guide says "Anytype’s servers can back up and sync your files, but they never hold the keys to read your content" (see 📝Sync / End-to-End Encryption). The client's code is published under the Any Source Available License 1.0, a source-available licence. In MythOS, every memo carries its own visibility: public, unlisted, hidden or private. Library Export downloads that library as 📝Markdown or as a fuller JSON export.
Structure and Linking
Anytype's documentation states, "In Anytype, everything you create is an Object." Each Object has a Type, "such as Note, Task, Project, Meeting," and Properties that hold its details. For inline links, "Type @ and the object name," and "You can use the Backlinks property in the Object Header to check which Objects link to the currently opened one." In its Graph, "Each Object is a node; each link or Property reference is an edge." In MythOS the unit is the memo. Typing @ draws a mention to another memo, and every mention becomes a 📝backlink, which is how the Graph maps a library's memos, daily entries, tags and collaborators as a 📝knowledge graph.
Sharing, Publishing and Agents
Anytype's collaboration guide states, "All spaces have multiple role levels, each with progressively higher privileges: Viewer, Editor, Admin, and Owner," and "Changes appear instantly when members are online, or on the same local network." Its Web Publishing "lets you turn any Object into a public webpage at a URL anyone can visit." Its Local API is "directly included with the desktop app, running entirely on localhost," and an official repository offers "An MCP server enabling AI assistants to interact with Anytype." MythOS exposes a library to MCP clients through mythos.one/api/mcp; 📝Claude on the web, desktop, iOS and Android signs in over OAuth, and a connected client gets 60 tools, with four identity memos (Soul, Style, Human and Memory) loaded before it writes. Memo Collaboration invites others to co-create.
Who Each Is For
Anytype's documentation calls it "a safe haven for your digital life," with Personal Spaces to "organize your diary, manage to-do lists, and store important documents" and Collaborative Spaces for "family, project teams, or entire communities." Its memberships page says "Anytype offers a Free tier plus several paid plans," which "Extend storage limits" and "Unlock unlimited shared Channels." MythOS's own overview says one library serves "private thinking, team collaboration, public writing, and the AI tools you work with." Its Plans & Tiers memo states that "writing is never the thing you pay for": its Free, Scribe, Scholar and Oracle plans sell reach, such as public publishing and agent access.
