I build Sendari to help YouTubers schedule marketing messages in their video descriptions

I had the idea for Sendari while watching videos on gamesinprogress.com, my passion project where we showcase a huge list of YouTube devlogs from indie game developers. Over time, I noticed a pattern: some devs used their video descriptions smartly to share news, promotions, wishlist links, or announce new releases. Others, even with hundreds of videos, hadn't updated their old descriptions to link to their current Steam game.

Watching those older videos sit idle while newer games launched felt like a missed opportunity.

So I started building a simple tool that would let creators insert promotional content into their video descriptions, schedule them, and target specific playlists. I tested the first version on my friend's YouTube channel, Scrum Life (https://youtube.com/@ScrumLife), and we began pushing campaign messages into older videos.

As the product evolved, I added automation so that new videos would include the right message the moment they went live. That removed the need for manual edits and kept messaging consistent across the entire video library. Later, I added click tracking to understand which messages worked and which didn’t, so they could be refined over time.

What began as a side experiment is now Sendari, a tool that helps YouTubers keep their video descriptions up to date and use them as a real marketing channel without extra effort.

Sendari is made for creators who have at least 50 videos. Below that, managing descriptions manually is still reasonable. But beyond that point, keeping things updated becomes tedious, and it's easy to miss opportunities to promote your work.

On Scrum Life, before using Sendari, updating and managing campaigns took around two hours per month. Between manual edits and switching between tools for tracking links and checking analytics, it added up. With Sendari, it now takes just 20 minutes. Everything happens in one place, and it's all automated.

Thanks for reading.
PS: There's a free test plan if you want to try it.
