Narration: synthetic voice. Script drafted with AI assistance. Ask an AI video model for a chart from your pitch, and it paints something that looks like one: from patterns, not from your figures. To it, letters are shapes, so words come out garbled; a number only has to look right; and nothing ties its chart to your pitch. Independent tests, and their makers' own reports, agree. When we tried one, with prompts from a video of Edwin Hubble's paper, it spelled the author Eovin Hubble, mangled our sister service's web address, and its chart had none of Hubble's data. What we do instead: our specialised AI agents draft the script, and you edit and approve it. Then our software draws every frame: typeset words, charts plotted from your pitch's own figures, diagrams in code. A synthetic narrator reads it. So every word, number and chart comes from your pitch and the script you approve. A whole seventy-second video, drafting included, used about fifty to ninety watt-hours when we measured it in September. One take of AI-generated footage used one point seven kilowatt-hours.
