Generate Narration From PowerPoint

TL;DR; Upload a .pptx file with no narrations at lupo.ai/projects/aislidenarrations. Lupo reads your slides and fills in the speaker notes with a professional draft script. Review, tweak, and use the output as the input to Create Video From PowerPoint.

Writing narration is the slowest part of making a training video. You know what you want to say — you just don't want to type it out, slide by slide, for 40 slides. This tool solves exactly that.

When to use this tool

Use Generate Narration From PowerPoint when:

  • Your slides exist, but the speaker notes are empty (or placeholder-y).
  • You want a first draft you can edit, not a finished one.
  • You want to nudge the AI toward a specific tone (executive, training, sales, longer narrative, etc.).

The output is a new .pptx file with the same slides, plus AI-generated narrations in the notes area. You can then feed that file into Create Video From PowerPoint to actually produce the video.

Step 1 — Open the tool

Go to lupo.ai/projects/aislidenarrations. The page is titled Generate Narrations Effortlessly for Slides using AI and you'll also find it in the Create menu as Generate Narration From PowerPoint.

Step 2 — Pick a model

Before you upload, choose which model Lupo should use. Three options:

  • Fast — draft-quality and quick. Good for a first pass when you just want something on the page.
  • Smart — uses slide text and any existing narrations. Better quality, slower. This is the default and the one most people should start with.
  • Premium (Visual Insight) — analyzes every slide as an image. This is the one to pick when your slides rely heavily on diagrams, charts, or screenshots, because the model literally "looks" at them. It's the slowest and most intensive option, but it writes the best narration when the visuals carry the meaning.

Step 3 — (Optional) Upload a knowledge base

If you have a style guide, glossary, or reference script you want Lupo to follow, drop it in the Optional knowledge base field. Accepted formats: .pdf, .txt, .md, up to 10 MB.

This is the best way to teach Lupo your terminology. If your organization calls something a "retro" instead of a "retrospective," put that in the knowledge base and Lupo will use the right word.

Step 4 — Personalize the tone

Under Personalize narrations, you can type a short prompt telling Lupo how to shape the tone, audience, and style. For example:

Executive-friendly: 3-5 sentences per slide. Clear and concise. Define acronyms on first use.

You don't have to write this from scratch. Under Templates (replace current text), Lupo gives you one-click presets:

  • Default — executive-friendly, 3 to 5 sentences per slide.
  • Executive concise — 2 to 3 sentences per slide, outcome-focused.
  • Stakeholder update — status update with impact, risks, and next milestones.
  • Sales pitch (CTA) — customer value and a clear call to action.
  • Training / How-to — step-by-step explanation in plain language.
  • Longer narrative — 5 to 7 sentences per slide with more context and examples.

Click the template you want, edit the prompt if you'd like to tweak it, and move on. You can undo template changes with Undo (or Ctrl+Z).

Step 5 — Advanced options (optional)

If you open Advanced options, you'll see a Preferred language selector. The default is Auto (infer from slides/prompt), which is almost always right. But if your deck is in one language and you want the narration in another, pick the target language here. Lupo supports English, Spanish, Portuguese, French, German, Italian, Japanese, Chinese, Hindi, and Arabic.

Step 6 — Drop your PowerPoint

Drag a .pptx onto the drop area (or click to pick a file). Lupo will show Uploading presentation..., then Starting voice-over job..., and finally Voice-over generation started.

Close the tab. You'll get an email when it's done.

Step 7 — Review and iterate

When the email arrives, you'll get back a .pptx with the same slides, but now the notes are filled in with Lupo's draft narration. Open it in PowerPoint and read through the notes:

  • Leave what's good alone. Most of it probably is.
  • Rewrite anything that sounds wrong. Specific product names, numbers, or one-liners you want exactly right are worth touching up.
  • Check the acronyms. If Lupo expanded one that shouldn't be expanded (or didn't expand one that should be), fix it.

When you're happy, upload the result to Create Video From PowerPoint to turn it into a finished video.
