Mem is built around its own AI chat and auto-linking — cloud-hosted, $12/mo. Morion gives you local notes and tasks your agents can use through MCP, plus Mo work packets and Auto-code loops when you want the board to drive real work.

Mem Chat is built into the notebook itself. If you prefer a single app for both writing and conversing, Mem bundles it together. Morion expects AI to live in your existing client.
Mem auto-connects related notes as you type. That graph is part of the pitch. Morion connects through search rather than building an explicit graph.
Mem is available on web and has an iOS app. Morion ships desktop builds today; mobile is not shipped yet.
Mem's cloud architecture is the product. For anything sensitive — journals, client work, research under NDA — that's a non-starter. Morion never uploads anything.
Switch between Claude Code, Codex, Cursor, Cline, or a future local model — the board stays the same. Mem ties your AI memory to Mem itself.
Mem caps free accounts at 25 notes and 25 chats per month. Morion is free and open source with no caps at all — unlimited notes, full MCP, full search.
Morion is free and open source (Apache 2.0) — Mo work packets and the Auto-code harness are included, run on your own LLM key. Mem Pro is $12/mo, about $144/yr, with their AI usage built in. Morion is the whole local notebook, task board, and MCP sync at $0, while Mem has no full free option.
Pick Mem if you want a packaged AI-notes experience with chat and auto-linking built in, and you're comfortable hosting your notes in the cloud.
Pick Morion if you'd rather own the data, bring your own AI, and give agents a local board with the context around each task.
Different jobs, different trade-offs. Mem sells cloud AI memory. Morion sells control, interoperability, and an agent work queue.
No account, no cloud, no telemetry. Your notes never leave your disk.
