PERSYS

A private AI console that keeps your files and conversations on your own device

On-device AI inference

Models run locally, so chats and prompts are processed on the device rather than in a remote data centre.

Works without internet

Chat, search, notes and the document library remain accessible with no connection, making the device useful offline.

Large local storage

Choose 1 TB or 2 TB of solid-state storage for photos, videos and documents, all kept inside the device.

AI-native apps

Private Chat, Deep Search, Smart Notes, Document Library, Private Gallery and Media Player are built for the hardware from the ground up.

Strengths & Pros

+Conversations and files never leave your hardware
+Fully usable offline, including AI chat and search
+Open source software aids transparency and trust
+Straightforward pricing with no subscription required

Limitations

–

On-device models are typically less capable than the largest cloud models

–You buy dedicated hardware upfront, a bigger commitment than an app

–Documentation pages were not reachable at the time of the check
