I built this browser extension many years ago and I got an offer for it. I'm planning to sell it for ~20k using the escrow.com. Source: 7 months ago

Another secret: Always read the policy of place that buyer offer for paying and stay away from direct deal, for example escrow.com and PayPal are where the most naive seller get scammed, buyer send payment on Goods&Services and use dispute option and take back his money after securing the account,.

Use a reputable escrow service such as escrow.com. They send the money, it's held by the third party service until they receive the info then once received the money is released to you. Fee is slight and better than being scammed. This one may be legit but the next probably not. Why take the chance. Source: about 1 year ago

I had selected escrow.com as payment method, because I have used it before, and while expensive, I trust that process. Source: about 1 year ago

Shipping for $50+ is free. I accept Cash App, Chime, FB Pay, GPay, escrow.com (buyer pays fees, I cover shipping & insurance), and using a middleman. Source: about 1 year ago

On the internet I only found the Android ML Kit which in my understanding only supports things like if the user has his eyes open or if the user is looking on the screen or looking away, etc. Otherwise I found SeeSo but the pricing of it after the 30 day test is huge with 1000$/month.
