AI tools can't share memory of your conversations—each tool starts from scratch, fragmenting your work across platforms

AI要約

•The problem: When you switch between ChatGPT, Claude, Gemini, or other AI assistants, each one has no record of what you told the others. You must re-explain context, repeat instructions, and rebuild information for every tool—turning multi-tool workflows into repetitive, disconnected tasks.
•Why it happens: Each AI company stores conversations in separate, locked databases with no way for tools to access each other's records. There's no shared standard or API (connection protocol) that lets one AI service read another's memory, so even if you want to string tools together, they operate as isolated silos.
•Who it hurts: Professionals juggling multiple AI tools (researchers using one for writing, another for coding, another for analysis) waste time re-briefing each tool. Students copying context between assistants lose efficiency. Teams trying to build AI-powered workflows hit dead ends when they need one tool to hand off work to another with full context intact.
•What needs to happen: The industry would need to agree on a shared memory standard—similar to how email works across Gmail, Outlook, and other providers—but AI companies haven't prioritized this because it doesn't lock users into their individual platforms.
