Elephas
Privacy-first Mac AI writing assistant that redacts PII before any cloud call and indexes your files locally.
Pick Elephas if you're a Mac-based consultant, lawyer, or analyst who wants Claude/GPT productivity without uploading raw client documents.
Skip it if you're on Windows or Linux, need a hosted team workspace, or want an open-source tool you can audit.
Elephas is a native macOS AI assistant pitched at professionals who can't pipe client data into a public chatbot. It indexes your documents on-device, redacts 28 categories of personally identifiable information before sending anything to a cloud model, and offers a fully offline mode for the most sensitive work. The headline features are 'Super Brain' (project-scoped knowledge workspaces built from PDFs, Word, Excel, Notion, Obsidian, Markdown, and Zoom transcripts) and 'Super Command' (a system-wide hotkey that drops AI writing and rewriting into any Mac app).
The target buyer is obvious: consultants, lawyers, accountants, financial advisors, and researchers who work under NDAs and want Claude or GPT without leaking names, SSNs, or account numbers. Elephas brings its own model bench (GPT-5, Claude, Gemini and 15+ providers via your own API key), so you can route confidential work to a self-hosted endpoint or a cheaper provider as needed. A 7-day Pro trial is available without a credit card; paid plans live on the pricing page.
Worth noting: this is a Mac-only desktop app, not a web product, and the Mac App Store build is deliberately crippled (no Super Command, no system-wide writing) because of Apple sandbox rules, so power users should install directly from the website.
Elephas is one of the few AI writing apps where the privacy story is more than a footer disclaimer: local indexing plus on-the-fly PII redaction is a credible answer for NDA-bound work. The Mac-only constraint and the gimped App Store build are real limits, but for the right professional it earns the subscription.
