deck.4hum.ai - The AI pitch deck builder that keeps working after the first draft.

Every hackathon team scrambles the last few hours to throw together a pitch. We built deck.4hum.ai to fix that - not with a one-shot AI generator, but with a real co-creation loop where you and the AI keep iterating until the deck is actually good.

The flow:

Describe your project → AI generates a full deck (title, problem, solution, tech stack, team) with real content
Iterate with AI in the sidebar → regenerate individual slides, rewrite sections, swap layouts - without blowing away your edits
Edit on the canvas → text, shapes, charts, diagrams, images, tables - all live-editable
Pick a professional theme → dozens of hand-curated presets, WCAG AA contrast enforced
Export as a video → type your script, AI narrates it, export MP4 - share a demo video link on Devpost, not just a PDF

What makes it different:

Iterative AI (LangGraph.js + Claude) patches individual slide objects, not a full regeneration
Client-side MP4 export via FFmpeg.wasm + WebCodecs - no server needed
13 editable object types: charts (ECharts, 11 types), Mermaid diagrams, tables, QR codes, device frames, and more
Designer-grade theme system with dozens of presets
