Open Context
Open Context is a portable AI context manager. Save your profile, your research, and your team’s shared references once — then any MCP-capable assistant can retrieve them, in any conversation, across any tool.
Your context stops living inside one chat window.
Install the Chrome extension, connect Claude or ChatGPT, and make your first retrieval.
