MemoryPlugin stores what you tell one AI tool and makes it available in every other one you use — say a rebrand to Claude, and ChatGPT already knows it next message. It can import history from 6 sources at once: one demo pulls roughly 15k tokens of context from 850 past conversations in about 3 seconds, versus an estimated 45 minutes of manual digging. It works across 21+ tools including ChatGPT, Claude, Gemini, Grok, Perplexity, DeepSeek, Mistral and MCP, with a 7-day free trial before billing starts.
