A playhead moves along the narration “A bowl. A ball. One. Two, three.” with a tick under each word. A bowl and a ball appear on the slide on their words. On each count word, the ball steps down the bowl and a box fills with that word's start time: 4.49 s, 5.26 s, and 5.77 s. A playhead moves along the narration “A bowl. A ball. One.

Quickstart
Install DeckTalk, build the scaffold without an API key, and then add your voice.Your first deck
Write one section across script.md, decktalk.toml, cues.json, and a page. Then verify its reveals.Requirements and costs
What DeckTalk needs on your machine, and which commands spend credits.

Understand the model

  • How it works: the seven stages, how DeckTalk finds narration t=0, and what decktalk verify checks.
  • Cues: how a cue such as 1.1bowl names the phrase a reveal starts on.
  • Writing for the ear: give every reveal a word to start on.
  • The page contract: how a slide talks to the recorder. Design a slide covers slide size, reveal effects, and the camera push.
