How It Works
Enter your video topic
Describe what the video covers in a sentence or two. The more context you give, the more relevant your description and chapters will be.
Generate the description
In one pass you get a keyword-led intro, calls to action, chapter markers, and hashtags, all laid out in the order YouTube viewers scan.
Copy and customize
Paste the description into your video, then swap in your real links, timestamps, and offers so everything points where you want it.
Popular Use Cases
Long-form videos
Give every upload a complete description with chapters and links so viewers can navigate and YouTube understands the content.
Tutorials and how-tos
Add timestamped chapters that map each step, making your tutorial easier to follow and more likely to be recommended.
Product and review videos
Build a description with clear calls to action and space for affiliate or product links right where viewers look for them.
Better search visibility
Work your main keywords into the opening lines so your video has a stronger chance of surfacing in YouTube search.
Pro Tips
Front-load keywords
Only the first two or three lines show above the fold. Put your main keyword and the value of the video right at the top.
Use real timestamps
Replace the placeholder chapter times with your actual moments. Accurate chapters unlock the chapter bar and help viewers jump around.
Add your real links
Swap in your genuine links to socials, products, or related videos. A description full of dead placeholders helps no one.
Keep hashtags focused
A few relevant hashtags help categorize the video. Adding too many can be ignored, so keep the set tight and on-topic.
Make the ask clear
Tell viewers exactly what to do next, whether that is subscribe, watch a related video, or grab a resource. One strong ask beats several weak ones.
