Integration details
Description
GrayMatter helps ChatGPT remember decisions, preferences, and project context so you do not have to repeat yourself. Search saved memories, assemble just the context a task needs, find reusable procedures, and inspect retrieval receipts. You control what is saved, updated, or forgotten; forgetting a memory requires your explicit confirmation. Your memories stay scoped to your account.
