MemryNote

The second brain that lives on your machine — not someone else's cloud.

Notes, tasks, projects, journal, calendar, and an AI agent that actually knows your work. All on your disk. End-to-end encrypted. Every feature a toggle.

Most note apps are a SaaS wearing a text editor. MemryNote is the opposite bet.

Install

macOS (Homebrew)

brew install --cask memrynote/tap/memry

macOS · Windows · Linux — grab the installer from the latest release.

That's it. Open it, point it at a folder, and your vault is yours.

What's inside

Six surfaces, one app. Turn off anything you don't use.

• Notes — Block editor, markdown on disk, backlinks, tags, instant search.
• Tasks & Projects — Due dates, priorities, recurrence. CRDT merge, so two devices never clobber each other.
• Journal — One file a day. Open in three keystrokes.
• Calendar — Time-block your tasks. Drag to reschedule.
• Inbox — Capture now, sort later.
• AI Agent — Bring your own model (Claude, Codex, local LLMs). It reads and writes your vault — with an approval step for every write.
• Sync — Optional, end-to-end encrypted, multi-device. The server only ever sees ciphertext.

Why it stays yours

• Local-first. Your vault is files on disk. Works offline. Always.
• End-to-end encrypted. XChaCha20-Poly1305 + Ed25519 + Argon2id. Sign out and it's unreadable to anyone but you — including us.
• Agent-native. The agent reaches your vault through a localhost MCP server. No third-party sees your notes.
• Yours to leave. Markdown on disk means you can walk out the door with your data any time.

A note from me

I'm Kaan. For years I bounced between four apps just to get through a day — and with ADHD, that jumping drained me before I'd started. I wanted one calm place that held all of it and an agent that already knew my work. Nothing did it without renting my brain back to me from a server I didn't control. So I built MemryNote. It's the app I wish I'd had.
