Mr. Mags

Auto-captures save-worthy facts from your AI chats and keeps them organized. Stays on your machine. Free for teachers.

Mr. Mags gives your AI assistants a memory — and keeps it on your own computer. Every time you open a new chat, the AI forgets you. You re-explain your job, your students, your project, your preferences, every single time. Mr. Mags fixes that. WHAT IT DOES - Auto-capture: when you type a fact worth keeping ("my student Sam has a 504 accommodation", "I have a meeting Tuesday at 4pm"), Mr. Mags saves it to your local memory before the message is even sent. - Inject memory: as you type, your relevant memories are prepended to the chat box automatically -- on by default, one click on the pill turns it off -- so the AI sees your context. - Save a reply: keep the AI's last answer to your memory with one click. - Organizes on its own: between conversations, Mr. Mags groups related memories together and lets you know what it noticed -- no extra effort from you. WORKS WHERE YOU WORK Claude, ChatGPT, and Gemini are supported out of the box, along with most other major AI chat sites — plus any custom AI site you add yourself. LOCAL BY DEFAULT Your memory lives on your machine, in the Mr. Mags app's local database. The extension talks only to your own computer (127.0.0.1). There is no Mr. Mags cloud server to send anything to — we can't read your memory because we never receive it. REQUIRES THE FREE MR. MAGS APP This extension is the browser half of Mr. Mags. It needs the Mr. Mags desktop app (Mac or Windows) running to store memories. Get it at https://mrmags.org. FREE FOR TEACHERS, FOREVER Teaching?

Local by default. Cloud-connected when you choose. Never both at once. https://mrmags.org
