AI slideshow maker for narrated video presentations

An AI slideshow maker turns slide decks, outlines, or articles into narrated video presentations. It reads your content, drafts a script and scene timing, then combines voiceover, visuals, and captions so users create slideshows as finished, exportable videos.

Yes. HeyGen applies clean layouts, your brand kit, and timed transitions, so a standout video looks produced rather than auto-assembled. You review and polish the script and design before rendering, so you can publish with confidence.

Common inputs include PPTX, Microsoft PowerPoint, Google Slides, DOCX, PDF, plain text, and URLs. Upload files or paste a topic to start, or move a finished script through the text to video flow when you know what each slide should say.

Yes. The AI generates narration from your script and times it to each slide, so you don’t have to record anything. Choose a preset or cloned voice to generate AI audio, then regenerate it to improve pacing whenever the script changes.

Upload the PPTX, let the AI read each slide and propose a script, then edit the lines and apply a template. The platform handles layout, timing and captions, and you render a shareable MP4 without rebuilding the deck.

Yes. Reopen the project, change the script, swap slides, or adjust branding, then regenerate the video. Versions are saved, so fixing a figure or refreshing a quarter’s worth of content takes minutes, not a full reshoot.

Yes. Captions are created from your script and aligned to speech timing, and you can export SRT files with the subtitle generator. Captions are suitable for muted viewing and improve how the video is indexed in search.

Yes. Upload your own images, screenshots, and stock visuals into slides alongside generated narration and music. This suits product showcases, event recaps, and social storytelling for any occasion where your own imagery leads.

Most slideshow videos perform best between one and ten minutes, depending on how in-depth the topic is. For longer material, split the content into shorter modules so viewers stay engaged and can rewatch specific sections on demand.

Many AI slideshow tools stop at static slides you present directly from a laptop. HeyGen produces finished videos with AI, realistic voiceover, captions, and translation into 175+ languages, so one project becomes a publication-ready global asset.

Yes. Because the script and design are reusable, output scales quickly on an easy-to-use platform. The agency Vision Creative Labs moved clients from 1–2 videos a year to 50–60 per day after adopting HeyGen for video production.

You can start with a free AI presentation and video workflow to create and export slideshow videos. The Pro and premium plans add longer durations, more voices, and brand controls, and pricing scales for teams producing higher volumes.

An AI presentation maker or AI presentation generator builds editable slide decks you finish manually. HeyGen goes further by turning those slides into a narrated video, which is why teams comparing the best AI presentation maker for video choose HeyGen over template-only tools.

Yes. Start from free presentation templates, then customise colours, fonts, and graphics to match your brand without a designer. The editor can enhance your creativity so non-experts still produce on-brand videos.
