# Zintus

> Zintus is a free, BYOK (bring-your-own-key) AI router. It routes prompts across
> 12 free-tier AI providers (Cerebras, Groq, Gemini, DeepSeek and more) with smart
> quota routing, sub-5ms overhead, and an Ollama offline fallback. On the default
> BYOK path your API keys stay in your OS keychain on your device and never reach
> Zintus servers. Available as CLI, Desktop, and Web. Free forever; optional paid
> tiers (managed keys) are coming soon. License: BUSL-1.1.
