NanoBanana PPT Skills

Visual-Heavy 2k Stars Open Source

Best for: Visual-heavy presentations, marketing decks, and creative pitches that need AI-generated images and animated video slides — not just text on a template

Not ideal for: Data-dense analytical decks, academic work, or presentations where animation and visuals would be inappropriate (e.g., legal, compliance)

Core Features

🎨

AI-Generated Images Per Slide

Each slide can have a custom AI-generated image created from the slide content. No stock photos, no placeholder rectangles — visuals are generated specifically for your message.

🎬

Video Transitions (HTML Player)

Generate short AI video clips between slides via Kling AI, merged with FFmpeg into an MP4 transition layer. Plays in the browser-based HTML player — not embedded in PowerPoint.

✨

AI-Generated Transition Videos (via Kling AI)

Kling AI generates motion video transitions between slides based on content context, merged via FFmpeg. Requires Kling AI account (primarily China market); international availability limited.

📣

Marketing & Creative Deck Formats

Optimized layouts for brand launches, product reveals, campaign pitches, and investor storytelling — different from the structured analytical formats of IB or consulting skills.

Architecture verified: Gemini text-to-image + Kling AI video transitions + FFmpeg synthesis — a complete AI visual presentation pipeline. Key finding: output is HTML+PNG (browser player), not .pptx. There is no PowerPoint file output. Visual Impact slightly adjusted because PNG/HTML output limits use in native PPT workflows. Ease of Use significantly lower: install command in prior page version was wrong (no requirements.txt exists), requires Gemini API key (15 free/day then paid), video features additionally require Kling AI account (primarily China market) and FFmpeg. Use bash install_as_skill.sh for the correct guided setup.
