CortexPlus
Search and store your notes, files, messages and tasks in a personal memory layer.
CortexPlus is a semantic memory system that indexes and retrieves your notes, files, messages, tasks and email. Muse can search your memory, fetch full items, save new notes and tasks, and build context from related information.
Try asking Muse: "Find my notes about the Johnson project and remind me of the key decisions we made."
