What they are
Plus AI
Plus AI is a native add-on for Google Slides and Microsoft PowerPoint that generates complete presentations from text prompts, PDFs, and uploaded documents, without routing you to a separate editor. It targets business professionals, consultants, and educators who need polished decks fast and already work inside Google Workspace or Microsoft 365. The Remix and Rewrite tools let you reformat or rewrite existing slides in one click. Output quality is solid for standard business presentations, but the tool struggles with highly technical or specialized content.
Synthesia
Synthesia generates studio-quality videos using AI avatars that lip-sync to a typed script, with no camera, microphone, or editing software required. It targets corporate trainers, marketers, and course creators who need to produce multilingual video content at scale. The output looks polished but has a recognizable AI avatar aesthetic that some audiences find less engaging than real presenters. Pricing starts at $14 per month on the Starter plan.
