Desktop app 0.1.0 — Signs of AI Writing for Windows

The desktop build of Signs of AI Writing. Same tool as the web app, in a window,
with nothing to install alongside it.

Download

SignsOfAI-Desktop-0.1.0-win-x64.zip — 64 MB, Windows 10 (1809+) or 11, 64-bit.

Unzip the whole folder somewhere and run SignsOfAI.Desktop.exe. Keep the folder
together: the .exe needs the wwwroot next to it.

Windows will warn you. The executable is not code-signed — a certificate costs
a few hundred dollars a year and this is a free tool — so SmartScreen shows
"Windows protected your PC". Click More info → Run anyway. If you would rather
not, the source is right here and dotnet publish src/SignsOfAI.Desktop builds the
same thing on your own machine.

No .NET install needed; the runtime is bundled. WebView2 is required and ships with
Windows 11 and any Windows 10 with a current Edge, so you almost certainly have it.

What it does

• Flags the tells of AI writing in English and Spanish — overused vocabulary,
  rhetorical crutches, syntactic tics, and a rhythm too even to be human — and
  explains how to fix each one.
• Rewrites them out as you type, on the device. No model, no network, no API key.
  When changing a word would break the sentence, it says so instead of breaking it.
• Originality checking between documents: shared passages, with the evidence.
• Interface in English or Spanish, switchable, independent of the language you analyse.

Nothing you write is uploaded. The analysis is ordinary C# running on your machine —
the same engine that is on NuGet as SignsOfAI.Core.

Honestly: what this version does not do yet

This first build does nothing the web app
cannot already do — it is the same interface in a window. It exists because a desktop
app can go where a browser tab cannot, and those are the next three things:

• Local models through Ollama. A page cannot reach localhost:11434 without you
  reconfiguring Ollama's CORS policy. From here it is an ordinary call.
• Predictability without a server. The perplexity model can run inside the app
  instead of calling one — offline, with nothing leaving the machine. The engine
  already ships as SignsOfAI.Onnx.
• Folders of documents. PDF, DOCX, ODT, EPUB, RTF, TXT and Markdown extraction is
  already in SignsOfAI.Documents; wiring it to a drop target is next.

If you are here from Reddit: thanks for asking for this. Tell me what you actually
need it to do — open an issue and
it will shape what lands next.
