Does Ed remember what I said in a previous conversation?

No, Ed doesn’t keep any memory from one conversation to the next.

This is a current limit of AI assistants, tied to the technology behind large language models (LLMs).

Two things to know:

1. Each new conversation starts from scratch

When you start a new conversation, Ed doesn’t know what you discussed before. Ed does, however, always have access to your groups, your assessments and your students’ results.

Your past conversations stay available in the “Conversations” panel: you can reopen one to pick up where you left off.

2. There is a length limit within a conversation

If a conversation gets too long, Ed may lose track of the beginning.

This comes from a technical constraint called the context window, which limits how much information the AI can “keep in mind” at any one time.

You can reach this limit if you work for a long time in the same conversation (going back and forth on grading, generating reteaching activities, etc.). When that happens, start a new conversation.

When a conversation can no longer continue, Ed tells you so and asks you to open a new conversation.

In practice: keep one topic per conversation, and start a new one when you switch tasks. Your assessment data is never lost: Ed finds it again in every new conversation.

🔍 So why does ChatGPT seem to “remember”?

ChatGPT has its own memory system: some important information is saved automatically and fed back into future conversations.

This relies on complex technical infrastructure that we can’t set up at our scale, for reasons of privacy, cost and control over teaching content.

🧠 Good to know:

AI memory is a fast-moving field. Many researchers are working on it, and these limits will be pushed back gradually over the coming years.
