YouTube Description Generator: Build a complete YouTube description with a keyword-rich hook, summary, chapters, links, channel info, a keywords paragraph and hashtags. It is free, needs no sign-up and runs in your browser. How to use it: 1) enter the title, keyword and a short summary; 2) add chapters and links, one per line; 3) copy the description and paste it into YouTube Studio. The first lines of a description show in search results and above “…more”, so the tool writes a hook of up to 150 characters that includes your keyword. It then adds your summary, a chapters block, a links block, a short about section, a natural keywords paragraph and hashtags.
How the YouTube description generator works
The first lines of a description show in search results and above “…more”, so the tool writes a hook of up to 150 characters that includes your keyword. It then adds your summary, a chapters block, a links block, a short about section, a natural keywords paragraph and hashtags.
The method
Chapters you enter with times are kept as they are. If you list chapter names without times, it adds 0:00 for the first and placeholders for the rest. YouTube needs at least three timestamps in order, starting at 0:00, each at least 10 seconds long. Links use “Label | URL” lines, and a live counter checks the 5,000 character limit.
The tool combines your inputs with tested copywriting frameworks such as AIDA, Problem-Agitate-Solve, Before-After-Bridge and Features-Advantages-Benefits. It adds industry word banks for more than a dozen niches, five tones of voice and call-to-action banks for booking, calling, buying, visiting, learning, enquiring and WhatsApp. It then varies sentence openings and removes near-duplicates, so every option reads differently. Click “Generate more” for a fresh mix.
Optional AI mode
When the site owner switches it on, an extra “AI version” button can write one more variation using Google’s free Gemini tier. Everything else works without it, with no sign-up and no credits.
Limitations
Fill in real timestamps after editing your video. Hashtags must be relevant; YouTube shows the first three above the title and may ignore all of them if you add too many. Do not add misleading tags or keyword lists.
YouTube Description Generator FAQs
How long can a YouTube description be?
Up to 5,000 characters. Only the first 100 to 150 characters show before “…more”, so put the keyword and main benefit at the start, then add details, chapters and links below. The free tool above is built around this approach, so you can try it in seconds and edit the result.
How do I add chapters to a YouTube video?
List timestamps in your description, starting with 0:00, with at least three chapters in ascending order and each at least 10 seconds long. YouTube then creates chapters automatically on the progress bar. Always review the final version yourself and make sure it fits your brand before you publish it.
Do hashtags in YouTube descriptions help?
Hashtags can help viewers find related videos, and the first three appear above your title. Use a few relevant ones. Adding more than 15 can cause YouTube to ignore all hashtags on the video. Small, consistent improvements like this add up over time and are easy to test.
Should I include keywords in my description?
Yes, naturally. Describe the video in plain sentences using your main keyword and related terms. Avoid long keyword lists, which add no value and can break YouTube’s spam policies. If you would like expert help, our team can review it and suggest practical improvements.
