Elephas

Elephas is a private AI assistant for Mac, with iPhone and iPad access to its knowledge bases. It indexes a user's PDFs, contracts and notes locally on the Mac, then lets them chat with those files, draft and rewrite text across apps, and ask questions grounded in their own sources. Cloud models from OpenAI, Anthropic and Google are available, and an Offline mode runs AI entirely on the device. The product is aimed at consultants, lawyers, accountants, researchers and financial advisors who handle client material they cannot paste into a public chatbot. Before anything reaches a cloud model, Elephas redacts 28 types of sensitive data, such as names, emails, account numbers and passport numbers, and the vendor states that its cloud AI uses zero data retention. A feature called Super Brain lets users build named knowledge collections and chat with them, with integrations for Apple Notes, Notion and Obsidian on higher plans. Windows support is listed as coming, with a waitlist. Every new download includes seven days of Pro without a credit card. Paid plans are billed monthly or yearly, and the yearly option saves about 17 percent. Standard is $19 per month for AI chat and writing across the Mac and basic document workflows. Professional is $39 per month and adds higher usage limits, integrations, Super Brain and iPhone and iPad access. Pro+ is $49 per month and adds a full redaction inspector, advanced redaction controls, optional offline workflows, maximum usage limits, a one on one onboarding call and priority support. Team use is handled through a contact form.
