Knowledge is a local-first personal knowledge base for capturing, organizing, and revisiting ideas over time. Write Markdown notes, organize them with folders, tags, favorites, and archives, connect related notes with [[wiki links]], search titles, content, and tags locally, and import web links, text, or files from the iOS share sheet. This version focuses on an offline-friendly, stable note-taking workflow. It does not require an account and does not rely on a custom server.
