About Elephas
Elephas is a native Mac and iOS AI assistant that learns from your personal documents, notes, and files to become your second brain. Unlike generic AI tools, Elephas answers questions with citations from your own knowledge base — PDFs, Word docs, Notion pages, Obsidian vaults, Zoom transcripts, and more — eliminating hallucinations. It works system-wide via a keyboard shortcut and supports offline mode for maximum privacy.
