It may say “Windows protected your PC”. The installer is signed by Augmented Mind AB; the warning is SmartScreen saying it has not seen this installer often yet, and it goes away as more people install it. Choose More info → Run anyway.
During setup it offers to fetch a made-up company's books, so you can watch it work with nothing of yours involved, the same demo the Mac has. It is new on Windows, so if it misbehaves, that is worth telling us and is not your fault.
Clerk.AI runs on your own AI subscription: Claude (Anthropic) or ChatGPT (OpenAI, through Codex). It drives Claude Code or Codex to do the work, so a close cannot start without one. The app says what is missing and offers to install it for you. Installing it is free; running a close needs one of those subscriptions. If you do not have one, tell us and we will find you another way to help, and please do not buy one for this.

There is a “Something wrong here? Tell us” link in the app. It shows you exactly what it would send before it sends anything, and it carries the logs, which is what makes a report worth acting on.
Everything is markdown in a folder on your own PC. Nothing is locked in, and uninstalling leaves that folder alone.
