Is AI-generated content 100% original and plagiarism-free?
Many AI writing tools produce unique content; however, it is advisable to use plagiarism detection tools to verify uniqueness since there could be instances where the generated texts are similar to some existing ones without the intention. -
Will AI writing tools take human writers' jobs?
AI tools are not replacements but rather facilitators of human work. The involvement of human inventiveness, decision-making, and deep comprehension is still very much needed in the production of quality content.
