Based on your query, I would recommend using SlidesAI. This tool is designed to transform text into professional, engaging presentation slides, which aligns perfectly with your need to turn class notes into a presentation.

Here's how SlidesAI can help:

• AI-Powered Slide Generation: You can input your class notes, and SlidesAI will automatically generate an outline and content for the slides. This feature can save you a lot of time in creating presentations.
• Design Suggestions: Based on the content of your notes, SlidesAI will suggest design layouts, color schemes, and fonts. This can help you create visually appealing presentations even if you don't have a design background.
• Integration with Google Slides: As a Chrome Extension, SlidesAI integrates seamlessly with Google Slides. If you're already using Google Slides, this feature will make the transition to using SlidesAI even smoother.
• Collaboration and Sharing: You can collaborate on presentations and easily share them with your students using Google Slides' collaborative features.

In terms of pricing, SlidesAI offers a free plan with limited features, as well as two paid plans: Pro at $10/month and Premium at $20/month. Depending on your needs and budget, you can choose the plan that suits you best.

Please note that while SlidesAI is a powerful tool, it works best with longer text input, which might increase your preparation time. Also, it currently only works with Google Slides, so if you're using a different platform for your presentations, you might need to switch.
