I built this because I got tired of the LLM-to-PowerPoint friction.
The workflow: Ask Claude/GPT to generate slides in HTML -> Paste into DeckBuilder -> Drag/drop to fix layout -> Export PDF.
Why single-file HTML?
No install, runs in browser
Works offline & Local-first
Git-friendly (clean HTML/CSS diffs)
~750KB total payload
The AI does the drafting; this gives you the finishing control locally.
Feedback welcome, particularly on the drag-and-drop feel and how the PDF export handles complex layouts!
