Beautiful.ai uses "Smart Slides" that automatically apply the rules of good design as you add content. It ensures that your charts, text, and images stay perfectly aligned and formatted, preventing the "clunky" look often found in amateur slides.

• Pros: Massive library of professionally designed templates; automatic alignment and color palette management; great for data visualization.

• Cons: Limited "free" tier; users who want complete manual freedom might find the "Smart Slide" constraints frustrating.
