Storyline: Merge/Concatenate Closed Captions

Hi BorgCube​  and MateuszSzuter-e​,

I recently worked on a large Articulate Storyline project that involved editing and syncing a significant number of captions. Doing all of that in Storyline's built-in caption editor would have taken a lot of time and effort.

So I built a tool with Claude.ai to make caption syncing and editing more efficient.

The tool reads a Storyline (.story) file, extracts the audio, video and captions, and provides an efficient way to edit and sync them. When a media file doesn't have captions already, I first use Storyline's AI caption generation, then refine and sync the result in the tool. Once the editing is done, I export the updated captions and import them back into Storyline. The tool does not make changes to the Storyline file directly.

Using the tool saved me a lot of time. I am happy to share it here in case it can be useful to other community members.

The tool is a single HTML file that runs in a browser, with nothing to install. Attached is a zip containing the html file along with a user guide in pdf.

Please do not hesitate to let me know if you identify any issues.
