Elements of AI: Introduction to AI
Elements of AI is a course from MinnaLearn and the University of Helsinki. Its official FAQ says the Introduction to AI certificate is free of charge, and it comes in digital form on your profile page. However, you must give peer reviews on certain exercises, and your own answers also need reviews, so it can take some time.
Do not mix it up with Building AI, the second course. Its content is free, but the shareable certificate costs €50 (including VAT, if applicable). Take Introduction to AI first, then start the Building AI course.

CS50 Introduction to Cybersecurity (Harvard)
You can audit the course for free on edX. Harvard Online lists a verified certificate at $449. Therefore, do not call the edX route free if you want that certificate.
A separate free “CS50 Certificate” comes from CS50 itself and is not identity-verified. Sample certificates say it covers five assignments and one final project. Check the current requirements on the CS50 site before you start.

Be Realistic About These Certificates
A free certificate shows that you finished a course. It is not a degree. We did not find accreditation claims on the official pages we checked, so do not present it as one.
Also, the learning is what helps you. Employers often look at what you can do, so pair a certificate with a small project or CV line. Finally, check each course’s rules, because some certificates need exercises, peer reviews or an exam.
