You need to write an important email. You know what you want to express, but it’s complicated and nuanced and multifaceted. Wouldn’t it be convenient if like in old times when many didn’t even know how to read and write, you could have someone do that for you cheaply and quickly?
On online service where you can get such a writer online immediately, talk with them to explain what you want expressed, facts, subtleties, feelings, etc., and have them write it for you and with you live online. No waiting, and fast results.
You toothaches or you have a splitting headache, maybe stomach cramps etc. It’s not a 911 situation but you need help now. This is for temporary help and comfort as well as quick diagnostic to know if further emergency help is needed.
Have an app where you can with just a few clicks describe the problem and get connected to a doctor (dentist, GP or any specialist) that can firstly get all the details, and secondly come over and help (examine you and give medication if needed). Doctors apply and specify when they are available, and the app connects them with the patients.
