HTML Decks vs Gamma
Gamma is the AI presentation generator — paste your content or topic, get slides. It's magic until you realize you're renting access to your own presentations.
AI generation is impressive
Gamma's AI genuinely produces decent presentations from prompts. Type a topic, get slides. For quick internal decks or brainstorming, it's remarkable.
The catch: you're dependent on their platform. No offline access, subscription pricing, and your presentations live on their servers.
Where Gamma wins
- AI generation — create presentations from prompts
- Speed — first draft in seconds
- Content suggestions — AI helps with what to include
- Modern design — fresh, contemporary aesthetic
- Document/deck hybrid — scrollable format that's kind of cool
Where HTML Decks wins
- File ownership — your file, works forever
- Offline presentation — present anywhere, no internet
- Design control — you decide what it looks like
- Price — $29 once vs. $8-15/month for Gamma
- Privacy — content stays on your machine
- Standard format — HTML is universal and permanent
The AI content problem
AI-generated presentations look like AI-generated presentations. They're fine for internal use, but for investor pitches, sales decks, or anything high-stakes? Generic AI content doesn't cut it.
Your pitch deck should sound like you. Templates give you structure; AI gives you commodity content.
Platform dependency
Gamma presentations live on Gamma. Export options exist but aren't great. If they raise prices, change features, or shut down, your presentations are affected.
HTML files work in browsers. That's not changing.

Is Gamma's AI actually good?
For quick drafts, surprisingly yes. For polished, high-stakes presentations, it produces generic content that needs significant editing.
Can I present Gamma offline?
You can export to PDF or PowerPoint. But the native Gamma presentation mode requires internet.
Is Gamma free?
Free tier exists with limits on AI credits and features. Useful features require subscription.
When should I use AI-generated presentations?
Internal decks, quick brainstorming, first drafts. Not for investor pitches, client presentations, or anything where generic content hurts you.
