Beginner friendly: Challenging

Data annotation and AI training can be challenging for beginners due to the technical skills required in labeling data accurately and understanding AI algorithms. While tutorials and courses are available online, the learning curve can be steep for those without prior experience in machine learning. Setting up this side hustle can range from $100 to $500 or more for software tools and training resources. It may take 2 weeks to several months to start earning a profit, depending on the individual's learning pace and accuracy in data annotation. I'd rate it a 1 because the technical knowledge and initial investment needed can be significant barriers for the average person without a background in AI.
