What OralSlides is
OralSlides is an online tool that turns a PowerPoint file into a video with an AI voiceover. You upload a .pptx deck, and multimodal AI reads the layout, text, charts, and images on each slide, then writes a speaking script and renders natural speech, exporting MP4. Your original slide design is kept, so nothing has to be rebuilt. Each slide has its own script and audio, which means a single page can be regenerated without re-recording the whole deck. Ten voiceover languages are supported, and subtitles can be added on paid plans. A free version includes 3 credits, while paid plans at $6 and $14.5 per month add watermark-free 1080P export and more voices.
What you can do with it
- Convert .pptx slides into narrated MP4 videos.
- Edit the generated script page by page.
- Choose language, voice, and speaking speed.
- Export video with subtitles on paid plans.
Who it is for
- Sales teams that send proposal videos to clients.
- Product and operations managers sharing async updates.
- Trainers who turn onboarding decks into course video.
What to watch out for
The free version exports 720P video with a watermark, so it is a test run rather than final delivery. Credits are deducted per page, so a long deck consumes them quickly. AI scripts follow the slide text but do not know how you actually speak, so read through and adjust before rendering. Free limits and pricing may change, and if your deck contains confidential figures, check the platform's data handling terms first. For best results, start with a small test file and review the output carefully before working on anything important.
