Oral Slides vs Synthesia

Slide narration vs. AI avatar video

Oral Slides compared with Synthesia

Synthesia is the leader in AI-avatar video: a digital presenter reads your script with a face on screen. Oral Slides skips the avatar entirely — your slides fill the frame and narration plays over them. Both produce MP4s. The question is whether the viewer should see a person or your content.

Best for

Teams who want the deck on screen, not a presenter — fastest path from PPT to a watchable MP4.

Not ideal for

Brand campaigns that require a human-shaped avatar to read the lines.

Pick Oral Slides when

  • You already maintain the deck in PowerPoint and want narration over it.
  • Your audience is internal — sales enablement, internal training, lectures.
  • You want the cheapest minute and the fastest re-export when content changes.

Pick Synthesia when

  • You need a human-shaped presenter on camera (e.g., onboarding to a brand).
  • You produce content in 50+ languages and need a single tool for all of them.
  • Your stakeholders explicitly asked for an AI avatar.

Workflow side-by-side

Oral Slides workflow

Drop the `.pptx` → multimodal model writes the per-slide script → pick voice + tone → review → export. Slides are exactly what you authored.

Synthesia workflow

Open the editor → paste or generate script → choose avatar and slide template → render. Closer to a video editor with a built-in presenter.

FAQ

Will Oral Slides ever support avatars?
Not on the roadmap. The product hypothesis is that the deck is the asset; the presenter shouldn’t compete with the slide for screen real estate.
Can I import a Synthesia project into Oral Slides?
No, but you can export PowerPoint from most slide tools and upload that.
