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.
Speechify
Speechify converts text from PDFs, articles, emails, Google Docs, and ebooks into spoken audio using AI-generated voices. It is used by students, professionals, and people with dyslexia or reading difficulties who want to consume written content faster or more comfortably. The voice quality is genuinely good at normal speeds, but at very high playback rates naturalness degrades noticeably. The free tier is limited to one standard voice and a capped speed.
