Beginner friendly: Moderate

Starting a side hustle in training AI data can be moderately challenging for beginners with no special skills or background. Online resources like tutorials on YouTube and forums can provide guidance, but understanding AI concepts may require some time and effort. The practical application of training AI data can be easier or harder than expected based on the complexity of the projects. Overall, with dedication and learning, most people can start earning a profit within 2 weeks. I'd rate it a 3 because while it requires effort to grasp AI concepts, it is doable for beginners who are willing to invest time in learning.
