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.

Pros & Cons

Pros

Answers are grounded in your own documents with cited sources, dramatically reducing AI hallucinations
Works system-wide via keyboard shortcut — accessible from any Mac app without context switching
Strong privacy guarantees: local storage, offline mode, no data used for AI training
Supports multiple AI providers (OpenAI, Claude, Gemini, Groq, local models) giving cost and privacy flexibility
Deep integration with popular knowledge tools like Notion, Obsidian, Apple Notes, and DEVONthink
Native Mac and iOS apps with iCloud sync provide a polished, platform-native experience

Cons

Mac and iOS only — no Windows or Android support, severely limiting cross-platform use
Monthly credit limits can feel restrictive even on higher-tier plans for heavy users
No control over document chunking strategy, which can hurt context quality for complex queries
AI response quality for highly specialized or technical tasks can lag behind direct API access
Occasional stability issues and minor bugs reported by users
