Persistent memory for Claude. Free for teachers, forever.
About

Named for the teacher who needed it.

Mr. Mags is named for a school teacher whose students call him Mr. Mags. He was the first user. We built it for him because his lesson plans, rubrics, and parent emails kept evaporating into one-shot AI chats that forgot him the moment he opened a new conversation.

Now Claude remembers him. Every conversation carries the context of every previous one — what he teaches, who his students are, the rubric he prefers, the cadence of his year.

Everything you tell Mr. Mags lives on your machine. Nothing leaves it. There is no account, no cloud, no server-side database with your name on it. The promise isn't "we won't read your data" — it's that we can't, because we don't have it.

For Teachers

Free. Forever. We mean forever.

No "free trial." No "free up to 10 students." No fine print. If you're a teacher with a school email, every feature we ever build — including features we charge other people for — is free for you.

Teachers are our best users. They put it through its paces. They make our templates better. So we don't charge them. They’re effectively contributing to product development, and they’ve already paid in time.

Verification is one click — confirm a school email, and the free flag lives on your install forever.
