📝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. 📝Reflect's site calls it "An open-source note-taking app with daily notes, backlinks, and local Markdown files." They split on where notes live: Reflect keeps them as files in a folder the user chooses, while MythOS memos can be published, shared and handed to AI agents over 📝MCP.
At a Glance
Files, Sync and Status
Reflect's repository says its 📝Markdown "files are the source of truth," kept in a folder the user chooses, the pattern described in 📝Local-First Software, and that "Git sync stores the Markdown graph in a repository you control." The MIT-licensed repository calls the project an "Open-source Reflect rewrite" and states that "Reflect is in beta and used daily." Reflect's site now presents two products, linking to "Meet Reflect Open" and "Log in to Classic," and says "Classic is still maintained." MythOS gives each memo its own visibility and keeps 13 months of Version History.
Daily Notes and Linking
Reflect's site lists daily notes ("Start with today's note"), the pattern described in 📝Daily Note, and networked notes ("Form a graph of ideas with backlinked notes"). In MythOS each day gets a 📝Daily Memo with a Tasks checklist and a Timeline. Typing @ draws a mention to another memo, every mention becomes a 📝backlink, and the Graph maps the library as a 📝knowledge graph.
AI and Agent Access
Reflect's optional AI can "Find answers with links to your notes, summarize text, and improve your writing." It says "Connect your own API key to get started. Requests go directly to your provider." Its repository names user-provided "OpenAI, Anthropic, Google, or OpenRouter keys" and lists CLI commands that "are available for scripts and agents." MythOS chat runs on six providers on a MythOS-funded balance or the user's own key through 📝BYOK. A client connected at mythos.one/api/mcp gets 60 tools.
Who Each Is For
Reflect's site states: "Our mission is to improve the way people think by making a jolly good note-taking app." 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"; plans sell reach, such as public publishing and agent access.

Reflect was my daily journal from April 2022 to mid-2025, more than eight hundred entries backlinked to the people, companies, and ideas in my life. I migrated that whole graph into MythOS, where it now lives as my daily memos.
