Quick answer

ChatGPT Memory carries remembered context across chats, with personalization controls that vary by surface. Hjarni adds a separate Markdown library, attributed note history and team permissions. Use both when native personalization and maintained documents serve different needs.

Use both, for different jobs

Native memory can reduce repeated context inside ChatGPT. Hjarni keeps deliberate notes with folders, tags, links and attributed versions. Its own permissions and the assistant’s tool approvals decide which actions are possible.

Make the same note available to different assistants

For a launch decision, ask one assistant to save the agreed reasoning in Hjarni. Later, ask another connected assistant to retrieve that note before drafting. Availability does not ensure recall: check the source and verify saved edits.

Client work is a common case. The Client Project Context template keeps one client brief for ChatGPT and Claude, so either assistant can read the same scope and decisions.

Common questions

Common questions

Does Hjarni replace ChatGPT Memory?

No. Native memory carries context inside ChatGPT. Hjarni adds explicit Markdown notes, sharing permissions and attributed history. You can use both. See official documentation.

Will ChatGPT still use its built-in memory if Hjarni is connected?

Connecting Hjarni does not disable native personalization. The memory and tool settings available on your account control how each feature is used.

Can I move my ChatGPT memory to Claude or Gemini?

Check what the source can export and what the destination accepts. A memory summary or prompt-generated export is not a guarantee that all remembered context moved. Review it before saving or importing it.

Why not just paste important notes into ChatGPT Projects?

That can work well for ChatGPT-centered work. Hjarni is useful when people and different compatible assistants should maintain the same note library. Projects, shared Space files and personal memory are distinct features.

Does Hjarni see my ChatGPT conversations?

Connecting Hjarni does not copy your conversation history into it. It receives the tool requests your assistant sends, including content you ask it to save. Notes are used when a permitted tool retrieves them.
