Pasting a YouTube URL after every upload is a step people forget. Here is how channel sync removes it - and what happens when SparkVox finds a new video before you do.
Sean Weisbrot- Founder, SparkVox
SparkVox has always supported pasting a YouTube URL when you start a new project - Sparky pulls the public metadata and captions, then runs the same drafting pipeline as an uploaded file. That workflow still works. The problem it never solved is the step before it: remembering to do it at all.
Most creators who publish to YouTube regularly do not sit down after every upload and think "now let me go turn this into LinkedIn posts." The video goes live, the next task takes over, and the recording sits in the channel doing exactly one job - reaching people who already subscribe on YouTube. LinkedIn never sees it unless someone remembers to manually bring it over.
Channel sync removes the remembering. Connect your channel once, and SparkVox checks for new uploads every hour on its own.
New Project → YouTube now has a dropdown above the URL field listing your suggested videos - thumbnail, title, publish date, and duration. Picking one skips the metadata lookup step entirely, since SparkVox already has it, and drops straight into moment extraction and drafting.
If you would rather not check the dropdown yourself, an optional email fires the first time a new video is synced, with a link straight into New Project with that video preselected. Turn it off under Settings → Notifications without losing the sync itself.
Not every upload is worth turning into LinkedIn posts - a housekeeping video, a livestream replay, a short you posted for YouTube's algorithm specifically. Suggestions you never pick simply expire after 90 days, so the dropdown does not fill up with stale entries. Picking a video, or manually pasting its URL later, marks it used either way.
Manual URL import remains the simplest path for a one-off video, a guest appearance on someone else's channel, or any link outside your own account. Channel sync is for the recurring case: a channel you publish to on a schedule, where the content is worth repurposing every time. Most people end up using both - sync for their own uploads, manual paste for everything else.
