Opening lines (208 characters): this is roughly what people see before they tap “more”, so the keyword and the promise should be here.

Improve this YouTube description for my video. Keep the structure, but make it sound like me and make the first two lines impossible to skip. About the video: - Topic / main keyword: meal prep - Who it's for: busy parents - The result or promise: save 5 hours a week - Tone: friendly - Main call to action: subscribe Rules: - The first two lines show before viewers click "more", so they must include the main keyword and say what the viewer gets. No "Hey guys, welcome back". - Keep any chapter timestamps exactly as they are. The first one must be 0:00. - Keep my links exactly as written. Replace anything in [brackets] only if I've told you what goes there; otherwise leave the brackets. - Keep 3 specific hashtags at the end (YouTube shows up to three by the title). No hashtag lists. - Stay well under YouTube's 5,000-character limit. Plain English, no buzzwords, no claims I haven't made. Then give me 3 alternative versions of just the first two lines. My current draft: Want to save 5 hours a week? In this video I walk busy parents through meal prep, step by step. You'll learn how to plan a week of dinners in 15 minutes, batch cook on Sunday and store food so it stays fresh. In this video: - Plan a week of dinners in 15 minutes - Batch cook on Sunday - Store food so it stays fresh Chapters: 0:00 Intro 0:45 Planning the week 3:10 Sunday batch cook 7:30 Storage tips Links mentioned: - Free meal plan: https://example.com/meal-plan - My containers: https://example.com/containers If this helped, subscribe so you don't miss the next video on meal prep. #MealPrep #MealPrepTips #BusyParents

How to write a great YouTube description

Front-load the first two lines. They’re what people see before tapping “more,” and they help YouTube and Google understand the video. Put your main keyword and the payoff there.
Summarize in plain words. A short list of what the video covers helps viewers decide to stay and helps search engines match the video to questions people ask.
Add chapters to anything longer than a few minutes. Start at 0:00, list at least three, and keep each one 10 seconds or longer. Clear chapter titles also work as mini-headlines for search.
Label your links. “Free meal plan: link” gets more clicks than a bare web address. Put the most important link first.
Ask for one thing. Pick a single call to action, like subscribe, comment, or grab the free guide. One ask is easier to act on than five.
Finish with 3 to 5 specific hashtags. YouTube shows up to three next to your title. Use tags that describe this exact video.
Reuse a template. Keep a saved version of your links and channel blurb so every upload starts from the same base, then rewrite the opening for each video.

Frequently asked questions

How long can a YouTube description be?

Up to 5,000 characters. You rarely need that many. What matters most is the opening: viewers only see the first line or two before they tap “more,” so put your main keyword and what the video gives them right at the top.

How do I add chapters to a YouTube video?

Add a list of timestamps and titles to your description, one per line, like “0:00 Intro.” YouTube’s rules: the first timestamp must be 0:00, you need at least three timestamps in order, and each chapter has to be at least 10 seconds long. Paste your timestamps into this tool and it checks all three rules for you. Chapters you add yourself replace YouTube’s automatic ones.

How many hashtags should I put in a YouTube description?

Three to five specific ones is plenty. YouTube shows up to three hashtags from your description next to the video title, and if a video has more than 60 hashtags, YouTube ignores all of them. Pick tags that describe this exact video, like #MealPrep, rather than broad ones like #video.

What should the first two lines of a YouTube description say?

Say what the video covers and what the viewer gets, using the words they’d search for. Skip greetings like “Hey everyone, welcome back.” For example: “Want to save 5 hours a week? In this video I walk busy parents through meal prep, step by step.” Links and calls to action can come further down.

Does this YouTube description generator use AI?

No. The description is built in your browser from a fixed structure, so it’s instant and nothing you type is sent or saved. You can edit it right on the page. To have AI rewrite it in your voice, copy the prompt into Claude or ChatGPT; it tells the AI to keep your links and timestamps exactly as they are.
