v0.3.3 shipped — cross-platform: macOS, Linux & Windows

One context vault.
Every AI tool reads it.

Memcrate is a portable, markdown-native, locally-owned personal context vault. Three verbs — /save, /pin, /load — over a defined vault shape any AI tool can read. No cloud. No lock-in. Just your context, in markdown, where you can see it.

Single static binary. Works on Linux, macOS (Intel + Apple Silicon), and Windows.

Three verbs

Save the session. Pin what matters. Load the context.

Same three commands across every supported tool. The vault speaks markdown — humans read it too.

/save

Compress the current session into a structured log. Decisions, learnings, files touched, pending next actions — written to Core/Sessions/.

/pin

Promote an insight from the current session into permanent context — Profile, Projects, or Current State. The bridge between session memory and durable memory.

/load

Load operating context at the start of a fresh session. Profile, active projects, current state, and recent session logs — your AI starts oriented, not blind.

The vault

A folder of markdown. That's it.

The Memcrate vault is plain text on your disk. No database, no proprietary format, no server. Every AI tool reads it through its own integration — Claude Code via skills, Cursor via rules, Cowork via MCP — but the source of truth is a folder you own.

Local-first, your sync. The vault lives in ~/vault. Use whatever you already have — git, iCloud, Dropbox — to mirror it across machines.
Tool-agnostic by design. Claude Code skills ship today; Cursor, Cowork, Aider, and an MCP server are on the roadmap.
Human-readable. Open any file in any editor. No “export” step, no lock-in.

Plays nicely with Obsidian

Open your vault in Obsidian. Sync it everywhere.

The Memcrate vault is just a folder of markdown, so Obsidian opens it natively — backlinks, search, a clean editor for the moments you want to browse your own context. Turn on Obsidian Sync (or use iCloud, Dropbox, or git) and every machine you work from sees the same vault.

“I'm tired of telling every AI tool where I left off.”

The reason Memcrate exists.

One context vault. Every AI tool reads it.
