Build a web app that turns a prompt, outline, or uploaded document into a polished slide deck. Numbered features: 1. Prompt-to-deck engine: user types a topic and audience, AI generates a 6 to 12 slide outline with titles and bullet content. 2. Document import: upload a Markdown, Docx, or PDF file and the app converts it into slides, one idea per slide. 3. Template themes: 5 pre-built themes with font pairings, accent colors, and layout options (title, bullets, two-column, image). 4. Slide editor: reorder, delete, and edit slides with a live preview. 5. AI rewrite per slide: tighten text, make it more persuasive, or simplify for a general audience. 6. Image suggestions: AI generates or fetches a relevant image for each slide. 7. Export to PDF and a shareable web link. 8. AI presenter notes generated per slide. 9. Tone controls: investor pitch, internal update, sales pitch, classroom lesson. Use an AI app builder with document parsing, image generation, and PDF export.
