I Replaced My Entire Marketing Team With AI Agents

By Samuel Gregory

About this video

In this comprehensive comparison, I put three leading AI agents head-to-head to see which one delivers the best results for business owners and productivity enthusiasts. I tested GenSpark, Manus, and Perplexity Labs with the same challenging task: building a lead magnet for a software development agency. Perplexity: https://samuelgregory.co.uk/perplexity Manus: https://samuelgregory.co.uk/manus Genspark: https://www.genspark.ai/ What I tested: Each AI agent was given the same prompt to research my company, analyze industry trends, and create a complete lead magnet with multiple options and full implementation. The results were eye-opening: GenSpark delivered a basic website calculator but lacked depth and had styling issues Manus provided the most thorough research process, transparent workflow, and comprehensive analysis across multiple dimensions Perplexity Labs offered solid results with good source gathering, plus the added value of being bundled with Perplexity's existing features Key takeaways: Manus emerged as the clear winner for dedicated AI agent work with superior UI and process transparency Perplexity Labs offers excellent value if you're already a Perplexity subscriber GenSpark showed potential but fell short in execution quality I also break down the pricing for each platform to help you make an informed decision based on your budget and needs. Whether you're a business owner looking to boost productivity or just curious about the future of AI agents, this comparison will help you choose the right tool for your workflow.
