Windows and Codex.
ThreadCast's first distribution is designed as a Windows desktop companion for the Codex app. Codex remains the owner of the tasks; ThreadCast reads and controls its own playback of selected task activity.

Spoken playback
ThreadCast stores its OpenAI API key in its own local Windows secret file. The buyer is responsible for OpenAI API usage charges, which are separate from the $5 ThreadCast beta price.
Android companion
The Android app connects to the Windows companion over loopback or Tailscale. It is not a standalone Codex client and requires the desktop companion to be available.
Beta status
The package has a per-user installer, guided API-key setup, an uninstaller, and an isolated fresh-profile launch proof. It is an unsigned early beta, so Windows SmartScreen may show a warning.
