📝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. 📝Tana's documentation describes Tana Outliner as "a knowledge management tool built on an infinite outliner with supertags, views, and AI features for personal and team use." Tana Outliner's documentation says the company now also ships "a separate, newer flagship product called Tana," and tana.inc describes that product as "the agentic meeting platform for teams."
At a Glance
Structure and Daily Capture
Tana Outliner organizes notes in an 📝outliner, and its documentation says "Supertags turn a node into a typed object with a template of fields." It adds that "Each day in Tana Outliner has its own page called a day node, giving you a fresh place to capture notes and tasks," Tana Outliner's form of the 📝daily note. Its docs also say "You can create additional workspaces and invite members to collaborate." 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 the library's 📝knowledge graph. Each day gets a 📝Daily Memo with a Tasks checklist and a Timeline, and Memo Collaboration invites others to co-create.
AI and Agent Access
Tana Outliner's documentation says it "runs a local MCP server inside the desktop app so AI tools like Claude Code and Cursor can search, read, and modify your workspace, and a hosted MCP server for connecting remote clients over the internet." Its Input API "is write-only and requires an API token per workspace," and each plan "includes a monthly quota of AI credits." MythOS exposes a library to any 📝MCP client through one endpoint, mythos.one/api/mcp. 📝Claude on the web, desktop, iOS and Android signs in over OAuth, and 📝Cursor connects by OAuth or an API key, which comes with Scholar and above. A connected client gets 60 tools for search, memo writes, templates, tasks and the daily journal, with four identity memos (Soul, Style, Human and Memory) loaded before it writes. Chat inside MythOS runs on six model providers, on a MythOS-funded balance or the user's own key; its Plans & Tiers memo says no plan includes AI credits.
Who Each Is For
Tana Outliner's documentation presents it "for personal and team use." 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.
