Notice how heartbeats prevent split-brain states.
:::Eliminate re-recordings, mismatched voiceovers, and tedious video editing. Treat video like compiled code.
Write standard Quarto Reveal.js or Markdown decks. Code chunks, formulas, and diagrams update your video automatically upon commit.
Decodes voice to 48 kHz uncompressed PCM. Video frames round on cumulative sample boundaries so audio and slides stay locked to the exact frame.
Pluggable TTS strategy supporting OpenAI, ElevenLabs, Azure Speech, Amazon Polly, Kokoro (offline neural), and Sarvam AI for Indic languages.
Two-pass EBU R128 loudness normalization (-16 LUFS integrated, -1.5 dBTP) built directly into the assembly pipeline.
Automated WebVTT and SubRip (.srt) generation matching exact narration timings, with optional burned-in caption rendering.
Pure CLI compiler for CI/CD automation and scripts, paired with a visual desktop studio coming for educators and content creators.
We are rolling out early builds of the Decktale compiler and desktop Studio to educators, technical speakers, and course creators.
