Elephas: AI Second Brain Assistant for Mac & iOS

Elephas is a native macOS and iOS knowledge assistant that transforms your scattered documents, notes, and files into an intelligent, searchable 'Brain' you can converse with. Instead of relying on generic AI answers, Elephas learns from your own PDFs, docs, presentations, and more across 20+ file formats, giving you a personalized ChatGPT-like experience grounded in your actual work and research. Organize different projects into separate Brains, then use Super Chat to ask questions, generate summaries, brainstorm, or pull insights straight from your own content. Beyond knowledge management, Elephas doubles as a system-wide AI writing assistant through its Super Command feature, which works inside virtually any Mac app to rewrite text, fix grammar, translate, summarize, or draft emails on the fly. It connects with popular PKM tools like Notion, Obsidian, DEVONthink, and Roam, keeping your existing workflow intact while layering AI intelligence on top. With a privacy-first design, end-to-end encryption, and the option to run fully offline, Elephas appeals to users who want powerful AI capabilities without handing their data over to the cloud.

1. Install Elephas on your Mac (and optionally iPhone/iPad). 2. Create a 'Brain' for a project or topic and link relevant documents in supported formats like PDF, DOCX, PPTX, HTML, MD, or TXT. 3. Use Super Chat to ask questions, request summaries, or brainstorm based on the linked content. 4. Set up WorkFlow Automations or Agents to handle repetitive tasks automatically. 5. Use Super Command inside any Mac app to rewrite, translate, summarize, or draft text using AI. 6. Sync additional PKM tools like Notion or Obsidian for deeper integration, and enable offline mode if privacy is a priority.
