Gamma.app generates a full 10-slide presentation in 2-3 minutes from a prompt. Beautiful.ai takes 5-10 minutes for the same. Canva AI takes 3-5 minutes. Manual PowerPoint takes 1-2 hours. The AI-generated slides need 10-15 minutes of manual editing (adjust images, fix text, align boxes) but that is still 4x faster than starting from scratch.
For internal decks, status updates, and quick prototypes: absolutely. For client-facing pitch decks, high-stakes board meetings, and design-heavy presentations: no, you need a human designer. I use Gamma for internal decks and Canva for client-facing work. The AI is good at structure and content but bad at brand consistency and design polish.
Gamma has a Brand Kit feature for paid plans. Beautiful.ai has theme customization. Canva has brand kits. Most tools support custom colors and fonts via their paid plans. Free plans give you generic templates. I have a brand kit set up in Gamma for saas.pet colors and fonts.
For speed, yes. For design control, no. PowerPoint and Google Slides give you pixel-perfect control. Gamma and Beautiful.ai give you speed and AI generation. I use Gamma for first drafts, then export to PowerPoint for final polish. The combination takes 30 minutes vs 3 hours in PowerPoint alone.
I've been testing and reviewing AI tools for 2+ years. I run saas.pet as a side project while working as a software engineer. I buy every subscription I review. No vendor pitches, no free accounts. If a tool is in my rotation, I pay for it.
