The problem with normal notes
Your notes are in one app. Your AI is in another. So every conversation starts from zero. You paste in the same background, re-explain the same preferences, and copy the same context out of an old chat. Nothing you told it yesterday carries over.
The fix is not a better note app. It is notes your assistant can actually reach.
How it works
Two steps. Save your notes in Hjarni, then connect it to ChatGPT or Claude with the built-in MCP server. From then on your notes are live context: your AI searches them, reads them, and writes new ones back, without you pasting anything.
Simple on purpose
Hjarni keeps the shape small: notes, folders, tags. That is enough structure for a knowledge base ChatGPT and Claude can read, search, and write without guessing where things belong.
What is left out matters. No databases, no kanban boards, no page builders. Those are useful in other products. They make a knowledge base heavier than it needs to be.
Your notes stay plain Markdown you own and can export. The point is not to model everything. The point is to keep durable context in a form both people and AI can understand.
Built-in AI memory is not enough
Built-in memory is useful for small preferences. A knowledge base is for context you want to keep, inspect, edit, and share across ChatGPT and Claude.
Use both. Let built-in memory keep light preferences. Put the notes worth keeping in Hjarni. See Hjarni vs ChatGPT Memory for the longer comparison.
What you keep in your notes
Keep the context you would otherwise repeat. The small facts. The current plans. The decisions that explain why things are the way they are.
Preferences
How you like answers written, what you avoid, what matters when options are close.
Trip details
Dates, bookings, places to revisit, dietary notes, and the kind of pace you prefer.
People
Who someone is, what you last discussed, and details you want to remember next time.
Ongoing projects
Goals, open questions, constraints, next steps, and useful background.
Decisions
What you chose, why you chose it, and what would make you revisit it.
Reference notes
Ideas, quotes, checklists, plans, and anything ChatGPT and Claude should be able to find later.
Start with one note
You do not have to import anything or set up folders first. Connect Hjarni, then tell your assistant one thing worth remembering. Paste this into ChatGPT or Claude once you are connected:
That first note is the whole idea in miniature. Your AI writes it, files it, and reads it back in the next conversation. From there you add notes, folders, and tags as you go. It is plain Markdown you own and can export anytime.
