Elephas is a private AI assistant for Mac that answers questions from your own documents while the files themselves never leave your computer. (★ 4.7 on Capterra)
Professionals routinely paste confidential contracts, reports, and client files into cloud chatbots because it is fast — and risky. Elephas is built for that work. You drop PDFs, Word documents, spreadsheets, slides, scans, and other files into collections called Brains; Elephas indexes them locally in an encrypted database and answers plain-language questions with citations that open the exact quoted passage and page. Before any question reaches a model, names, emails, and phone numbers are automatically hidden and restored in the answer, and you can see precisely what was masked. You also choose where answers are generated: the included Elephas AI, your own API key for providers such as OpenAI, Claude, or Gemini, or a model running entirely on your computer, in which case nothing is sent anywhere. A Team plan adds shared Brains with end-to-end encrypted sync for firms that need one private place to ask.
Personal costs $19/month ($15/month billed yearly at $180) for one computer. Professional costs $29/month ($24/month billed yearly) with double the included AI usage, three computers, and optional encrypted sync. Team costs $29 per person per month ($24 billed yearly) with shared Brains and pooled usage. Every plan starts with a free 7-day trial, no card required.
Elephas is for consultants, lawyers, researchers, engineers, and small firms whose documents are confidential by default and who want sourced answers from their own files without uploading them to a chatbot.
