Create SlidesA detailed, honest comparison of two AI presentation makers — features, export quality, and what each tool does best.
Try SlideMaker.app FreeSlideMaker.app is a free AI presentation maker — a learning personal project, not a commercial product.
Gamma and SlideMaker.app are both AI-powered presentation tools, but they take fundamentally different approaches. Gamma positions itself as an AI document and website builder that also does presentations. SlideMaker.app is purpose-built for creating, exporting, and sharing slide decks — and it is completely free. This comparison uses real feature data from both platforms so you can decide which one fits your workflow.
These are capabilities that SlideMaker.app offers and Gamma does not.
SlideMaker.app turns any presentation into a video with configurable slide durations, transitions (fade, slide, zoom), AI voiceover with 4 voice options (Rachel, Adam, Bella, Josh), background music across 6 genres, and full 1080p output. Gamma has no video export at all.
SlideMaker.app exports presentations as platform-optimized carousels for LinkedIn, Instagram, Twitter/X, and Facebook. Each format is sized correctly for its platform with file size estimation. This is a feature no other AI presentation tool offers.
SlideMaker.app allows sharing presentations with a password gate so only authorized viewers can access them. Ideal for confidential pitch decks, internal reports, and client presentations. Gamma does not offer password protection.
Shared links can be set to expire after 1 hour, 24 hours, 7 days, or a custom date. This controls exactly how long content stays accessible. Gamma shared links remain active indefinitely.
SlideMaker.app accepts PDF or Word document uploads (up to 20 MB) and converts them into structured slide decks, preserving headings, content hierarchy, and key points. Gamma cannot convert existing documents into presentations.
SlideMaker.app is completely free with no credit limits. Gamma gives roughly 10 free presentations before requiring a $10-20/month subscription.
SlideMaker.app exports to MP4 video with voiceover, transitions, and background music. Gamma has no video export capability.
SlideMaker.app generates social media carousels for LinkedIn, Instagram, Twitter/X, and Facebook. Gamma does not support carousel export.
SlideMaker.app offers password-protected sharing and link expiration. Gamma shared links are permanent and open to anyone with the URL.
SlideMaker.app converts PDFs and DOCX files into slide decks. Gamma cannot import or convert existing documents.
Gamma's PPTX export frequently breaks layouts according to user reviews. SlideMaker.app preserves themes, gradients, and animations in PPTX export.
Gamma includes view analytics (scroll depth, time per section). SlideMaker.app does not have presentation analytics yet.
Gamma creates documents, websites, and social posts in addition to presentations. SlideMaker.app is focused exclusively on slide decks.
Gamma is a strong AI tool for creating web-native documents and websites alongside presentations, and its analytics feature is genuinely useful for tracking engagement. However, for users who need reliable exports, video output, social carousels, secure sharing, or document-to-slides conversion — SlideMaker.app is the stronger choice. SlideMaker.app provides all of this completely free, while Gamma's useful features are locked behind $10-20/month plans. If PPTX export quality matters (and it does for most business and education use cases), SlideMaker.app's theme-preserving export is significantly more reliable than Gamma's, which is the single most common complaint in Gamma's user reviews.
