From document to explainer video in three steps
There is no storyboard to draw and no timeline to edit. Upload what you have, and the AI handles the production.
Upload your source material
Start with what you already have: a PDF, website link, Word document, presentation, or screenshots. SlideSpeak reads it and finds the story worth telling.
Solar output grew in every region we serve this year.
Next-gen panels cut costs while boosting efficiency.
RegenerateSmart grids tie it all together, storing power for when it's needed.
Let AI write and narrate the script
Next, the AI drafts a clear script, builds widescreen scenes from your content, and narrates them with a natural voice. You can edit every line before rendering.
Export and share your video
Finally, download a polished HD video for your website, sales outreach, onboarding, or training. Most videos are ready in minutes.
Add your logo and the video matches your brand
Most explainer video tools produce generic clips. SlideSpeak instead builds a brand kit from your logo and applies it to every scene.
