Based on your query, Beautiful.ai could be a great solution for you. It's an intelligent tool that can help you enhance your existing PowerPoint presentations with better templates and designs.

One of the key features of Beautiful.ai is its Design AI. This feature uses machine learning and natural language processing to automatically identify the most important parts of your slides and enhance them with visually appealing designs. This means you don't need to be a design expert to create stunning presentations.

Another useful feature is the drag-and-drop editor and pre-made templates. These can help you quickly and easily revamp your slides, allowing you to focus more on the content and less on the design.

Additionally, Beautiful.ai offers real-time team collaboration. This could be particularly useful if you're working on group projects or school-wide presentations.

However, it's worth noting that some users have mentioned that Beautiful.ai is more focused on business presentations and the trial version can be limiting. Also, the pricing may not suit everyone, especially when compared to other tools. Therefore, I recommend taking advantage of the 14-day free trial to see if it meets your needs before making a commitment.
