A personal knowledge base helps someone capture, connect, search, and develop information across projects and time. It may use folders, links, tags, metadata, full-text search, indexes, or graph relationships to make notes discoverable.
Agent access can help summarize, link, and update notes, but it also increases permission and integrity risks. Local-first storage, version history, bounded access, source citations, and review help preserve ownership and prevent silent corruption.

A personal knowledge base is a collection of notes and information organized so one person can find and reuse what they have learned. It is like a private wiki that grows with their projects and interests.
For example, Markdown notes about books, meetings, and ideas can link to one another and become searchable. An AI agent may help organize them, but it should not silently rewrite or expose private notes without permission.
