What to save in your AI knowledge base: 5 recipes

Your AI starts from zero every time.

It does not remember your customers. Your decisions. Your writing style. Your old meeting notes.

Hjarni is a simple knowledge base your AI can read. Save notes once. Claude and ChatGPT use them as memory.

That sounds useful. But what do you actually put in it?

Think of this as a recipe book. Each recipe is a small workflow. Notes go in. The right context is there. Work gets done.

Recipe 1: Customer memory for support

The setup. Every time you have a meaningful exchange with a customer, save a note. Tag it with the customer or company name.

A question. A complaint. A promise. A weird edge case. Anything you might need later.

The payoff. Two months later, that customer emails again.

You ask: "What is the context on Maria from Studio North?"

Claude reads the notes and gives you the history.

No CRM ceremony. No digging through old email. Just the context you need.

Ingredients. One note per meaningful exchange. Tags for customers or companies. A naming convention you will actually stick to.

Recipe 2: Meeting notes into action

The setup. After each call, paste your meeting notes into Hjarni. One note per meeting.

Do not clean them up too much. Do not make it a project. Just save the notes while the call is still fresh. Or let an AI listen and write the note for you.

The payoff. At the end of the week, ask:

"What did I commit to this week?"

ChatGPT reads the meeting notes and gives you a clean list.

Next week, ask:

"What did I promise the design team last month?"

You get the answer without hunting through docs, chats, and calendar events.

Ingredients. One note per meeting. A folder for meeting notes. The habit of dumping notes within five minutes of a call.

That is the only hard part.

Recipe 3: A decision log

The setup. When you make a real decision, write it down.

A pricing change. A hiring decision. A feature cut. A launch delay. A product bet.

Write what you decided. More importantly, write why.

Tag it decision.

The payoff. Six months later, you will forget why half of those choices made sense.

You ask:

"Why did we decide not to build the team plan in Q1?"

Claude reads the decision notes and gives you the reason you wrote at the time.

Not the version you reconstructed later. The actual reason.

Write it once. You both remember.

Ingredients. Five minutes after the decision is made. One tag: decision. Enough context that future you will not have to guess.

Recipe 4: A style guide your AI follows

The setup. Write a note that captures how you write.

Short sentences. No jargon. No em dashes. Direct tone. Plain words. Whatever your rules are.

Save it in a folder called Style.

The payoff. Any time you ask Claude or ChatGPT to write something, point it at that note.

It has your rules. It writes more like you.

Blog posts. Emails. Replies. Landing page copy. Support answers.

You stop correcting the same mistakes every time. I run Hjarni's own marketing this way.

Ingredients. One honest style note. A few examples of writing that sounds like you. A few examples of writing you hate. Clear rules your AI can follow.

Recipe 5: Inbox leads, handled by your AI

The setup. A lead form on your site. Or a contact email. Zapier picks up new leads. Each one becomes a Markdown note in a Hjarni folder called Leads, tagged lead.

The payoff. You ask Claude or ChatGPT: "Draft replies for new leads this week."

It reads the lead notes. It checks your past replies. It writes follow ups in your voice.

You review. You send.

No copying context into the chat. No explaining again who you are, what you sell, or how you reply.

Ingredients. Zapier. A Hjarni folder called Leads. A few examples of your usual replies. One tag: lead.

Hjarni stays small on purpose

It is a place to write and organize what Claude and ChatGPT should remember.

Notes, folders, tags. Markdown. The MCP server is built in.

That is enough.

Start with one recipe.

A customer note. A decision. A writing rule. A meeting dump.

Save it once. Use it forever.

That is the point of Hjarni:

Write once. You both remember.
