Elephas

Elephas is an AI writing assistant and personal knowledge management platform built primarily for macOS, iPhone, and iPad users. It combines AI-powered writing with a “second brain” approach, allowing users to organize documents, notes, PDFs, emails, and web content into searchable knowledge bases. Instead of acting solely as a text generator, Elephas helps users retrieve information from their own files, summarize documents, draft emails, rewrite content, and answer questions with citations from their personal knowledge library. The platform supports multiple AI providers, including OpenAI, Claude, Gemini, Grok, and local LLMs, giving users flexibility in choosing their preferred models. Elephas integrates with Apple applications such as Apple Notes, Mail, Pages, and productivity tools like Notion and Obsidian. It also includes an AI writing keyboard for iPhone and iPad, enabling users to write, edit, and rewrite text across virtually any app. Privacy is a major focus, with local AI model support, offline processing options, and user-controlled data. Whether you’re a researcher, writer, consultant, student, or business professional, Elephas helps centralize knowledge, automate writing tasks, and improve productivity across Apple devices.
