YoyoTools runs ScamCheck, Sub Audit, and other free utilities from a basement server. No venture funding. No signup walls. Just tools people forward in group chats.
Mochi is the tuxedo cat who supervises from the rug. She has a heart-shaped white patch on her face and opinions about suspicious texts. When tools help you avoid a scam or spot subscription creep, she accepts tribute in the form of $1 treats — via PayPal or Venmo.
Mochi speaks (technically a yawn, same energy):
Why a treat jar beats ads
- Scam victims shouldn't see sketchy ads on a safety tool
- $1 is impulse-friendly — less than a vending machine snack
- Pet lovers donate to cats, not "tip the developer"
- Every treat is counted live on the site (see admin dashboard)
