DeckSpeaksAI turns a slide deck into a narrated video that sounds like you. You upload the deck, the script is written per slide, and your own cloned voice reads it.
I built it for my own lessons first. Thirty-two of them went through it, which is how the voice pipeline behind my other videos was shaped.
The app is live; the voice and caption rules it follows are the same ones I use on every site here.
