Versions and AI memory
A version is a writing path
Each version starts from a saved draft and has its own conversation. The version history lets you return to an earlier draft or compare saved work. Ungraded loads the conversation for the version you are viewing; it does not mix every past version into the current chat.
When writing settings change
Changing the stage, tone, citation style, instructions, output format, draft length, or another setting that guides the AI starts a new version when a saved draft is available. The new conversation begins from that saved draft and uses the updated preferences. Earlier turns remain in the previous version because the AI cannot retroactively rewrite the instructions used for those answers.
Changing a due date or scheduled completion date does not change the writing instructions, so it keeps the current conversation.
What the memory indicator counts
AI memory is the working context Ungraded prepares for the next turn in the active version. It includes your assignment and saved draft, your questions, earlier AI answers, and unseen system instructions and writing preferences that help the AI continue the conversation coherently. The indicator estimates the size of that combined context; it is not a count of visible chat text alone.
For example, “17,000 / 20,000 memory remaining” means roughly 3,000 memory tokens are already occupied by those combined inputs and responses. It does not mean the AI has generated 3,000 output tokens or used that many pages. Only AI-generated output counts toward the separate page allowance.
When AI memory fills up
Your plan determines the available working memory. The indicator warns you as the limit approaches. Before a follow-up would exceed it, Ungraded starts a new version from the current saved draft and continues with a focused conversation instead of replaying the entire old chat. The earlier conversation remains available in its previous version.
Memory is an estimate of the context sent to the AI, so it can change when the draft, settings, or conversation changes. It is separate from your page usage.
