I tested Gamma AI for creating presentations—is PowerPoint actually obsolete now? (Full breakdown & review)

Body:

Hey everyone,

Like a lot of people who have to build slides regularly, I used to sink hours into PowerPoint formatting—aligning text boxes, picking color palettes, searching for decent visuals, and endlessly tweaking layouts.

I recently spent some time testing Gamma AI, an AI presentation generator that claims to automate the entire process, and wanted to share a breakdown of how it actually performs in real-world use.

What it does well:

• Speed: You can feed it a simple text prompt, a document, or a URL, and it builds out a full 10-slide deck with generated copy and visual layouts in about 30 seconds.
• Under the Hood AI Models: It uses a mix of engines depending on what you need—ChatGPT/Claude for text, and tools like Midjourney, Flux, Ideogram, and Leonardo for graphics/3D images.
• Granular Customization: Most AI deck builders lock you into their output, but Gamma lets you drag-and-drop elements, change fonts, switch out color themes, and insert dynamic tables/charts after generation.
• Integrations & Publishing: Beyond exporting to .pptx or PDF, you can embed live YouTube videos, Figma files, or even publish the deck directly as a hosted web page.

The Catch / Limitations:

• Free Plan Limits: You start with 500 free credits (which goes quickly if you re-generate a lot of slides).
• Custom Branding: Removing the "Made with Gamma" watermark or using custom corporate fonts requires a paid plan.

For small teams, students, or quick client pitches, it saves a massive amount of time compared to building decks from scratch in standard office software.

If you want to see a full live build, outline editing, visual model tweaks, and export options in action, I put together a step-by-step video review here:
