Frequently asked questions
Is this course about spotting AI fakes free?
Yes. Every lesson is free to read. The checkers the lessons name, such as the Verify site and the SynthID detector, are the vendors' own pages. Lesson 3 says what Verify and c2patool need, and for the SynthID detector it can only repeat that Google DeepMind calls it available to everyone.
Can an AI image detector tell me for sure?
No. Lesson 1 and lesson 2 give the research: people were wrong on almost four in ten pictures in one study, and in another none of the commercial detectors evaluated reached 90% accuracy. Treat any single result as one clue.
What is the fastest habit to learn from this course?
Leave the message and check at the source. Lesson 2 does it for a call, with a number you saved, and lesson 4 does it for an email, by opening the service yourself.
Do I need to install anything?
No. A phone and a browser cover every lesson. Lesson 3 also shows c2patool, a command line tool, for readers who want to read a file's credentials on their own computer.
What should I learn after this course?
The prompt engineering course for beginners is next. It teaches the other half, asking an AI for what you want and getting an answer you can use, and its first lesson builds one prompt in five passes.
