Elephas

Elephas is a Mac-native AI assistant built for people who work with sensitive information and care about privacy. It creates a local knowledge base from your documents and puts an AI assistant a keyboard shortcut away in any app — helping you write, summarize, and research while keeping your data on your machine rather than shipping everything to the cloud.

What is Elephas?

Elephas is a macOS application that acts as a private AI knowledge workspace and writing assistant. Its Super Brain feature lets you build focused workspaces by uploading PDFs, contracts, notes, and research, all indexed locally on your Mac, so you can ask questions grounded in your own material. Super Command is a keyboard-shortcut assistant that works across Mac apps like Mail, Slack, and Safari for writing, summarizing, and editing wherever you are. Privacy is central: Elephas can redact many types of sensitive data before any cloud processing and offers an offline mode for entirely local operation. It supports multiple AI models — OpenAI, Anthropic’s Claude, Google Gemini, and others — and is distributed via direct download and the Mac App Store, with a free Pro trial.

What it does well

• System-wide assistant: Super Command works across any Mac app via a shortcut.
• Local knowledge base: Super Brain indexes your documents on-device.
• Privacy-first: sensitive-data redaction and an offline mode.
• Model choice: works with OpenAI, Claude, Gemini, and more.

Who it is for

Elephas fits Mac professionals — consultants, lawyers, researchers, writers, and knowledge workers — who want an AI assistant that respects privacy and works everywhere on their Mac. It is especially appealing to those handling confidential documents who are wary of sending everything to the cloud. Windows users are out of luck since it is macOS-only, and people wanting a simple web chatbot may not need its depth, but for privacy-conscious Mac users, Elephas is a standout.

Things to keep in mind

• It is macOS-only, so Windows and Linux users cannot use it.
• Cloud models still process some data unless you use offline mode.
• The full feature set requires a paid plan after the trial.

Our verdict

Elephas is one of the best AI assistants for Mac users who value privacy, combining a locally indexed knowledge base with a system-wide command that works in any app. The privacy features — sensitive-data redaction and offline mode — genuinely set it apart from cloud-only assistants, and multi-model support keeps it flexible. It is limited to macOS and its best features are paid, but for Mac professionals handling sensitive documents, Elephas is an excellent, thoughtfully designed choice with a free trial to try.
