Sygen: AI Assistant

Run your own AI agents on a server you control. Bring your own provider keys; every chat and file stays private. Self-host free, or add a managed cloud server.

Sygen is a self-hosted AI agent platform for iOS. Run your own AI agents on your own infrastructure — Mac mini, VPS, or any server you control — and use them from anywhere through this clean, native iOS companion app.

Unlike SaaS chat apps, every conversation, file, schedule, and integration lives exclusively on your server. Time Design LLC, the developer of Sygen, has no servers in the loop and no access to your data. You bring your own AI provider keys (Claude, OpenAI, or others), you set the rules, and you keep ownership of everything you produce.

WHAT YOU CAN DO IN SYGEN • Chat with any number of AI agents you configure on your server, each with their own personality, prompts, and tools. • Send voice messages, attach photos and files, share screenshots — agents see them in context. • Forward messages between agents and let them work together through inter-agent calls. • Schedule recurring jobs (cron) — your agents run on a timer, summarize a feed, send a reminder, post to a webhook. • Receive webhooks — give external services a URL that triggers an agent. • Track running tasks and active sessions in real time, see logs and audit history.

DESIGNED FOR iOS 26 • Native Liquid Glass interface throughout — refractive toolbars, glass cards, dynamic typography. • Compact, content-rich layouts: Dashboard summary, Activity grid, full-feature chat with rich media bubbles, session pin / archive / rename gestures. • Optimized for iPhone, with iPad multitasking support.

PRIVACY-FIRST BY ARCHITECTURE • Sygen does not track users. No App Tracking Transparency, no IDFA, no analytics SDKs. • No third-party data collection of any kind. • All app traffic is HTTPS / TLS. Authentication tokens live in iOS Keychain. Face ID is handled by Apple's Secure Enclave and never leaves your device. • Privacy manifest declares only the strictly necessary required-reason APIs (UserDefaults for app preferences, file timestamps for cache freshness) — both fully inside the app's container.

WHO IT'S FOR Power users, developers, and small teams who want the convenience of a polished iOS chat experience without giving up ownership and control of their conversations and automation.

REQUIREMENTS • iOS 26 or later, iPhone or iPad. • A self-hosted Sygen backend on a server you control. The Sygen project provides setup guides for Mac mini and VPS deployments. • An API key from an AI provider you choose (Anthropic, OpenAI, etc.) — configured on your server, never inside the iOS app.
