GrayMatter
ChatGPT pluginSecure memory for AI agents
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.
