K-Portal BrainWeave is an AI knowledge platform that turns every employee's daily work records into a personal Second Brain — and, for the first time, lets that brain be transferred, merged, and queried collectively. Organizations everywhere watch expertise walk out the door with vacations, transfers, and retirements; handover documents never capture how an expert actually thinks. With BrainWeave, employees simply work in a block-based collaborative editor while AI automatically extracts keywords, relationships, and summaries into a searchable knowledge graph reflecting each person's role and context. One click shares that brain with a colleague — view-only for a vacation, full merge for a resignation — without copying data, and with instant revocation. Merged brains become an organization's collective intelligence: in a twenty-thousand-employee company, for example, the CEO can question all their accumulated knowledge at once and receive grounded, cited answers. BrainWeave makes organizational memory permanent, transferable, and alive.
