Beautiful.ai charges $12-40 a month, forever, for auto-layout slides. The auto-layout logic is the whole product, and your decks live in their cloud. Slidecraft does the same reflow trick entirely on your machine, for $29 once.

• Content-aware smart layouts — Title, bullet list, two-column, image+text, chart, quote and agenda layouts recompute font sizes, columns and spacing automatically so nothing overflows or overlaps.

• Theme system — 5 palettes plus font pairings apply globally and carry zero geometry, so swapping a theme never breaks a layout.

• Native charts — Bar, line and pie charts from typed-in data render as vectors in the editor and PDF, and export as real editable PowerPoint charts, not screenshots.

• Speaker notes + presenter mode — Full-screen presenting with next-slide preview, a notes pane, an elapsed timer and keyboard navigation.

• Real exports — .pptx via pptxgenjs opens in PowerPoint, Keynote or Google Slides, and 16:9 vector .pdf via pdfkit, both running headless in pure Node.

• Own your files — Decks are plain-JSON .slidecraft files you can version in git if you like.

Runs as a Windows desktop app.
