Build a memoryyour AI can't lose.

Everything you know becomes a knowledge graph you can chat with, and a master prompt for any AI.

Start building your memory See how it works

Free while in beta. Your data stays yours.

Tired of explaining yourself to AI?

Every conversation starts from scratch. It is frustrating, inefficient, and it never gets better on its own.

Repetitive explanations

Every new AI conversation starts from zero. Your background, goals, and preferences, retyped again.

AI has no memory of you

ChatGPT, Claude, Gemini. Each one forgets you the moment the chat ends. Your context doesn't compound.

Inconsistent results

Different answers every time, because the AI never has the same picture of who you are and what you need.

Up and running in minutes

No setup, no prompt engineering. Three steps and your memory starts working for you.

Add what you know

Answer a short guided interview, drop in notes, or upload documents. Ten minutes is enough to get started.

We build your graph

Every fact is embedded and connected into a private knowledge graph of your people, projects, goals, and preferences.

Chat and export

Ask your memory anything and get cited answers, then export a master prompt that makes any AI know you instantly.

Your memory becomes a knowledge graph.

Master Prompt AI reads what you tell it and connects the people, projects, goals, and preferences into a living graph you can see, explore, and chat with.
