Grandma

grandma
A memory layer for Claude Code that learns as you work.

Your AI forgets everything between sessions. Every morning you re-explain your stack, your conventions, your client, your life. Grandma fixes that. She gives Claude Code a persistent memory that is yours (plain markdown in your own git repo), separated by sweater (one per part of your life, kept apart), and learned passively while you work.
A sweater is a context you keep separate memory in — one company, one client, your
job hunt, your writing. Open a sweater and grandma remembers everything about *that* part
of your life and nothing from the others. Your projects live inside a sweater.

Grandma does three things a single session never can:

- Keeps your worlds apart. Client A's memory never shows up in a client B session — enforced by a test, not by discipline.
- Remembers across all of them, forever. Tell her once, in any session; every future session in that sweater knows.
- Analyzes your whole history and acts on it. She can study weeks of your chats and turn what she finds into memory:

Here is the everyday loop. Teach her once, and a brand new session already knows:

Watch it happen:

Install

That clones the engine, creates your private memory home, and offers a two-minute interview where grandma learns who you are. Or manually:

Requirements: Claude Code, git, jq, python3. macOS or Linux (Windows via WSL). grandma doctor checks everything and tells you how to fix what is missing.

Update

The engine is a git checkout, so updating is a fast-forward:

Update always lands you on master, whichever branch the engine checkout is on, and it only ever fast-forwards: no force, no rewritten history. If you have been hacking on the engine, uncommitted changes to tracked files stop it with a list of what it…
