Sample PDF Upload Feature Added

You can now upload sample PDFs to try out the service even if you don't have a PDF.

You can now upload a sample PDF to try SpeechSlide AI easily, even if you don't have a PDF of your own.

SpeechSlide AI is a service where you upload a presentation PDF, the AI automatically generates a speech script from the content of each slide, and you can create a narrated MP4 video with AI voice. Previously, you needed your own materials even just to try the service. With this feature, you can now experience the entire flow — from upload to script generation to creating a narrated video — without preparing any materials.

If you would like to see how the service works first, please walk through the flow with the sample PDF and then try it with your own slides. The basic steps are introduced on our How to Use page.

Please feel free to give SpeechSlide AI a try.
