Drop a PowerPoint storyboard on it. Get voiceover-ready narration files, or a clean copy of the deck with the internal notes stripped for handoff. The source file is never modified.
Narration sits in the notes pane, underneath the slide it belongs to, next to stage directions written for whoever builds the course. [Animate the pressure arrows along the line] is a note to a developer. It has no business being read aloud. Getting a clean file per slide by hand means opening the deck, copying the notes, deleting the bracketed directions, saving a text file, naming it so it sorts, and doing that sixty-three more times before zipping the lot.
Getting narration out meant loading a macro that wrote back into the storyboard itself. Fine on one file. Across eight storyboards in parallel that is eight open files and eight chances to corrupt the one everything else depends on. It has, on a deadline.
Timed against a real, sixty-four slide course: open the deck, copy each slide's notes, strip the brackets, save, name it so it sorts. Same operation every time, nothing about it ever changing from one slide to the next.
A weekly task, close to an hour each run, across a whole team. Call it thirty-plus hours a year and the math clears the bar easily. A forty-minute task done twice a year would not have, and saying so is as much the job as building the fix.
Narration EX reads the storyboard and writes everywhere except back into it. The original never even gets opened, so there is nothing to corrupt. No macro to load, no Office install to depend on, and it runs the same way every time, on any machine. The spec was written in plain English before any code existed: what goes in, what comes out, every edge case known from years of doing the job by hand. An AI assistant built to that spec. What ships is deterministic, and the content never left the machine to build it.
The case for it, then the tool actually running end to end. Both open in place, nothing leaves this page.
Pull narration for voiceover. Drop the storyboard and get a zip with one text file per narrated slide.
When the storyboard itself is the deliverable and it is full of internal notes never meant to leave the team.
