yoyosup 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. He has a heart-shaped white patch on his face and opinions about suspicious texts. When tools help you avoid a scam or spot subscription creep, he 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)
Try the tools Mochi supervises
- ScamCheck — paste suspicious texts, get instant risk score
- Sub Audit — true yearly subscription cost
- PassCheck — password crack time (runs in browser)
- Guide: protect parents from scams
Why a tip jar exists at all
The checkers and guides are free on purpose. Hosting, domains, and time still cost something. Optional tips and—when approved—ads help keep the lights on without forcing a subscription wall in front of someone who just got a scary text.
What your support does not change
- ScamCheck stays usable without paying
- We still avoid hard-sell ads on pure panic result UX
- We still do not sell the contents of pasted messages
If you only do one thing
Forward a guide or ScamCheck link to a family group chat. Distribution helps more people than a single tip—and it is free. Questions go to the Contact page or Feedback on tools pages.
