Elephas
Elephas is a Mac writing assistant that indexes PDFs, notes, and client files locally so you can chat with your own documents without pasting them into a browser tab. Its Super Brain workspace redacts 28 types of sensitive data before cloud models see your content, and offline mode keeps everything on-device when you need it.
ChatGPT and Claude expect you to re-upload files each session. Elephas builds a persistent local knowledge base from Apple Notes, Notion, Obsidian, Word docs, and Zoom transcripts, then cites sources from your actual files. Pro+ adds a redaction inspector that shows exactly which names, emails, and financial details were masked per message.
Elephas targets consultants, lawyers, accountants, researchers, and financial advisors handling NDAs. Plans run from a free 20-credit tier through Standard at $19/mo, Professional at $39/mo, and Pro+ at $49/mo, with a Mac and iOS app and support for GPT-5, Claude, and Gemini.
