Private AI that lives on your phone.
Nowhere else.
The Premsys App runs AI models entirely on-device. Your convos, health data, and documents get processed on your phone. No datacenters. No accounts. No ads. Ever.
The P in Premsys stands for Privacy.
The Premsys App processes your data locally, by design. Here's how it works:
Your chats stay on-device.
Every conversation runs directly on the AI model living in your phone, not at some datacenter. Prompts and responses are never transmitted, logged, or used for training. Delete a chat, and it's gone.
Files are indexed locally.
With Premsys Pro, the AI builds its document index on your phone. Your PDFs, notes, and contracts are searchable without ever uploading a single byte, thanks to enterprise-grade RAG technology.
Tool permissions are controlled by iOS.
Calendar, Health, Reminders, and Weather data all go through Apple's permission system. Toggle them off in the App, or revoke them at the OS level in iOS Settings. Premsys only sees what you grant.
Web searches go to Brave only when used.
Search is off unless you activate it. When you do, only your query goes to Brave for processing, with no account attached.
Results come back to your local AI model.
Get unlimited web searches with Premsys Pro.
Go Free or Go Pro.
Both tiers run AI locally on your device. Premsys Pro adds a larger AI model, document intelligence, unlimited web search, and file creation for $12.99 a month.
