Your AI sent you here
“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 read them in every conversation, and save new ones as you go.
Why your AI suggested this: it forgets everything between sessions. A memory it can read fixes that. Sent here by Claude instead? Same steps.
Free to start. No credit card required. First, what is Hjarni?
The 60 second setup
Three steps. Then it remembers.
No download, no config file. You sign up, connect once, and go back to your conversation.
01
Create a free account
Sign up with Google or email. You land in a short connect wizard.
02
Connect your AI
The wizard shows the exact steps for ChatGPT or Claude. You paste one URL and approve the connection.
03
Go back to your conversation
Tell your AI to remember something. It saves a note here and reads it back in every future chat.
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.
What you’re connecting
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.
Write once. You both remember.
Your next conversation can start from what you know. Not from zero.
Free to start. No credit card required.
