Rosalena Harness for Windows

The desktop app runs on my machine every day, but it isn't packaged for other people yet: there's no installer and it isn't code-signed, so Windows would block it. When the first build is ready to share, the download goes right here.

Where it is

What works today, and what's left before a download

Works now

  • The model router, with fallback when a model is busy
  • The agent: tools, plugins, subagents, voice input
  • The desktop window and the model picker
  • Local pictures, video and music through ComfyUI
  • An MCP server so other tools can start and read runs

Left before a public download

  • A single-file app that doesn't need Node installed
  • An installer
  • Code signing, so Windows SmartScreen doesn't block it
  • Voice as an optional download (it needs a Python runtime)
What it needs

What you'll need to run it

Windows 10 or 11. You don't need a big graphics card to start: the free cloud models work on any PC. To run models on your own machine, more graphics memory means bigger models; the 27B model I use takes about 20 GB on an RTX 3090.

SetupWhat you can run
Any Windows PCThe free cloud models (DeepSeek V4.1 Flash and GLM-5.3 Flash on a free cloud tier), plus paid models if you add your own key
A graphics card with 24 GBfor example an RTX 3090 or 4090Qwen3.8 27B locally, plus local pictures, video and music
