# “ChatGPT told me to set up a memory.” Here’s how.

You’re in the right place, and this takes about a minute. Hjarni is a knowledge base your AI can read and write. You keep notes here. ChatGPT and Claude search and read them when a conversation calls for it, and save new ones as you go.

Why your AI suggested this: its built-in memory holds a few facts, not your notes. A memory it can read fixes that. Sent here by Claude instead? Same steps.

## Three steps. Then it remembers.

No download, no config file. You sign up, connect once, and go back to your conversation.

1. **Create a free account**

   Sign up with Google, Apple, GitHub, or email. You land in a short connect wizard.

2. **Connect your AI**

   The wizard shows the exact steps for ChatGPT or Claude. Both list Hjarni in their connector directories, so you click Connect and approve the sign-in.

3. **Go back to your conversation**

   Tell your AI to remember something. It saves a note here and can read it back in any future chat, when the conversation calls for it or when you ask.

Rather stay in the chat? After you sign up, paste `https://hjarni.com/llms-full.txt` into the same conversation and your AI finishes the setup itself. [How that works](https://hjarni.com/docs/use-with-your-llm).

## Not a black box. A notes app.

### Your notes stay readable

Everything is plain Markdown. You can open, edit, and export every note your AI writes. Nothing is hidden from you.

### One memory, every assistant

The same notes work in ChatGPT, Claude, and anything else that speaks MCP, the standard your AI probably mentioned. Stop re-explaining yourself to each one.

### You stay in control

Your AI only sees what you keep in Hjarni. Disconnect it anytime, and your notes stay yours.
