What "private" and "offline" should mean
Private means the company running the sync server cannot read your content. That requires end-to-end encryption, where notes are encrypted on your device and the server only stores ciphertext. Encryption at rest on the vendor side does not meet this bar, because the vendor holds the keys.
Offline means the full workspace runs on your machine: opening, editing, searching, and planning, with no spinner when the connection drops. A cached copy that becomes read-only offline is not the same thing.
There is a third property worth adding to the list: ownership. If your notes are stored as files you can open without the app, leaving later is a folder copy rather than an export project.
memrynote: the Notion workflow, on your own disk
memrynote keeps the parts of Notion most people use daily, notes, tasks, and planning, and runs them locally. Notes are Markdown files with frontmatter properties in a vault folder you choose. Tasks live in projects with custom statuses, subtasks, and Kanban, list, and calendar views. A daily journal and a capture inbox sit in the same workspace.
Everything works offline with no account. When you turn on sync, each item is encrypted on your device with XChaCha20-Poly1305 and the server stores only ciphertext. Local use is free and sync starts at $5 a month. The app is open source and runs on macOS, Windows, and Linux.
Switching is built in. Export your Notion workspace as Markdown & CSV, then use the Notion importer in memrynote settings. Pages become Markdown notes and databases become structured notes in your vault.
Shared workspaces are coming
Today memrynote is a private workspace synced across your own devices. Shared vaults and collaboration are on the roadmap, built on the same end-to-end encryption.
How other private, offline options differ
Anytype is local-first and end-to-end encrypted, built around typed objects. Its working format is its own object store, with Markdown available on export. AFFiNE is an open-source workspace that combines documents and whiteboards, with local and cloud workspaces. Obsidian stores notes as local Markdown files; tasks and calendars come from community plugins, and encrypted sync is a paid add-on.
The right pick depends on how you used Notion. If you mostly wrote documents and tracked your own work, a local workspace that covers notes and tasks together replaces it with the fewest moving parts.
| App | Where your notes live | Notes + tasks + calendar |
|---|---|---|
| memrynote | Plain Markdown files you own | Built in, encrypted sync included |
| Anytype | Its own local object store | Built from object types and views |
| AFFiNE | Local or cloud workspace | Docs and whiteboards |
| Obsidian | Plain Markdown files you own | Through community plugins |
A simple way to decide
List the three things you open Notion for most often. If they are notes, a task list, and some planning, try memrynote with an imported copy of your workspace for a week. It costs nothing, needs no account, and your Notion workspace stays untouched while you compare.
Key Takeaways
- A private Notion alternative needs end-to-end encryption, not vendor-side encryption at rest.
- Offline should mean the full workspace runs locally, including search and planning.
- memrynote covers notes, tasks, a calendar, and a journal locally, with encrypted sync and a built-in Notion importer.
- Plain Markdown files make leaving any app later a folder copy instead of an export project.
