Elephas
Mac-native AI writing assistant with a private local knowledge base.
About
Elephas is a system-wide AI writing assistant for macOS. Its Super Brain workspace indexes PDFs, notes, Apple Notes, Notion, Obsidian, and transcripts locally, letting users chat with their own documents with source citations. A redaction layer masks 28 types of sensitive data before anything reaches cloud models, and an offline mode keeps everything on-device.
Invoke it from any Mac app with a keyboard shortcut to draft, summarize, rewrite, and automate writing workflows. Plans run from a free 20-credit tier to Standard at $19 per month, Professional at $39, and Pro+ at $49, with support for GPT, Claude, and Gemini models.
