Elephas

About Elephas

Elephas is a Mac-native AI assistant built for the work you cannot paste into ChatGPT. Its whole architecture is organised around that constraint: your documents, notes and files are indexed 100% locally on the machine, an offline mode runs fully on-device, and when you do choose a cloud model the app redacts 28 categories of sensitive data before anything leaves the Mac. Cloud calls that do happen go to zero-data-retention endpoints, and the model choice is yours — GPT-5, Claude and Gemini are all available — so the privacy posture is a set of controls rather than a blanket refusal to use frontier models. That makes the target audience unusually specific for an AI writing tool: consultants, lawyers, accountants, researchers and financial advisors, people whose material is under NDA or professional privilege and who therefore cannot use the mainstream assistants at all. Functionally it does AI chat and writing across the Mac, works against your PDFs, notes and files, and offers document and note workflows, with an iOS companion. Every new download activates seven days of Pro automatically with no credit card, requiring macOS 13 or later, and the app is also on the Mac App Store. Tiers escalate on AI usage allowance, control and the number of redaction types, and the company reports more than 3,000 professionals using it.
