Create structured slide decks from a topic. Arka uses presentation-specific prompts (action titles, speaker notes, section dividers) — not video scripts.

Quick start

Style presets

Visual themes

Control colors and typography with --theme:
Design features per deck:
  • Title slide with subtitle and logo placeholder
  • Section dividers (pitch decks use Problem/Solution sections)
  • Left-aligned action titles with accent bar and slide numbers
  • Footer bar with slide title and page number on content slides
  • Image/chart placeholder panel on text-only content slides
  • Metric callout boxes on pitch traction slides
  • 8px spacing grid and WCAG-friendly contrast on all themes
  • Max 4 bullets per slide (≤8 words each)
  • Speaker notes in narration; minimal on-screen text

Plan before you export

Use plan mode to preview the design improvement steps without generating files:

Export formats

Slides save to ~/Documents/arka-slides/ by default.
If pptx validation fails, Arka removes the invalid file and saves a markdown outline instead. For Keynote users, PPTX exports stay conservative by default; enable speaker notes only with SLIDES_PPTX_NOTES=1.

Quality bar

  • One idea per slide
