As answered by people managing CHECKHC and StackBlitz.
CHECKHC's answer
CheckHC is the only consumer solution combining AI deepfake detection, official C2PA certification, blockchain registration, and permanent Arweave storage (200+ years) in one click.
CHECKHC's answer
CHECKHC's answer
CheckHC was born from a simple observation: in a world flooded with AI-generated content and deepfakes, proving authenticity is becoming impossible.
Founded in France, CheckHC gives creators a simple, affordable way to certify their digital content before it gets stolen or manipulated. We believe every valuable digital content will soon need a "birth certificate" - and CheckHC provides exactly that.

CheckHC = digital birth certificate for your creations, from €0.09.

I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.
StackBlitz claims to allow you to code the future in your browser. And after trying it, I’m confident you’ll agree that this web application is extremely useful for coders.
