Windows SmartScreen warning during alpha. While Cyréna is in alpha, Windows may show a SmartScreen or Defender warning when running the installer. This is expected for unsigned applications — click More info → Run anyway to proceed.

System Requirements

8 GB RAM minimum
500 MB free disk space
libwebkit2gtk-4.1-0 (Linux only)
Ollama (optional, for local models)
Local models need more resources. Running AI models locally (via Ollama) requires additional RAM and VRAM depending on model size — typically 4–16 GB extra. Cloud models like OpenAI have no extra requirements beyond the base 8 GB.

Cyréna HUD

A Heads Up Display that keeps Cyréna always within reach.
