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.
Substack
Substack is a publishing platform where writers host email newsletters and charge subscribers a recurring fee. Independent journalists, essayists, and niche experts use it to build direct audiences without relying on ad revenue. The platform handles payments, delivery, and a basic website automatically. Substack takes a 10% cut of paid subscription revenue on top of stripe fees, which becomes a real cost as an audience grows.
