User reviews

Not good for practice. Everything you write will be 100% wrong. Even if you do put the right answer

For the very first 2 problems, i put the right answer. They were very very basic problems but the grader kept telling me i was wrong. When i got the app to show me the answer, it was word for word what i wrote.

I literally have screenshots of this and will be deleting this useless app. As soon as i downloaded it, they wanted me to pay for pro. So i guess getting people to pay money for a subscription is more important to this team than trying to make an app that actually works. I wonder if the code to receive my credit card info is also bugged or is it just the main function of the app thats bugged. Dont download it. Waste of time.

Response from developer

You were right, and I'm sorry it cost you the time. The answer checker had a real bug: it compared your SQL in a way that could never match a correct answer like city = 'London', so right answers were marked wrong. That is why the solution it showed you was word for word what you had written. It is fixed as of version 1.25, with tests around the checker so it cannot come back quietly. If you give the app another try, those first two challenges should grade correctly now. If anything is still marked wrong, email me at support@ai2sql.io with the screenshot and I will fix it. - Mustafa, developer
