Slides as a single HTML file. Written by your agent.
No build, no server, no framework.
Decklight is built in the Reveal.js tradition, with every feature designed so a machine can prove the deck works: WCAG-gated themes, truthful terminal recordings, and a voice that can present for you. The deck below presents itself.
Author a single HTML file, double-click it, present. file:// is enough, and decklight bundle flattens a whole course into one email-able file.
Describe a slide in plain English and an agent answers in Decklight, with overflow guards, contrast gates and headless render checks standing in for eyeballs.
Progressive builds from one attribute, Magic Move between slides, and theme-aware SVG diagrams that literally draw themselves in.
Every theme passes WCAG gates and codified palette rules; diagrams and terminals reskin too. Press ⌃T in the deck and it generates a brand-new one.
Real PTY recordings replayed truthfully (never video), plus live TTS narration that presents the deck by itself, captions and pop quiz included.
No install needed: npx runs the CLI straight from npm. This terminal is Decklight's own player, replaying a recorded session (press ▶ to run it again).
