How to Use AI to Write YouTube Video Descriptions

Quick Answer

Give AI your video title, what the video covers, and your target keywords. Use the prompt to generate a full description with an SEO hook in the first line, a content summary, timestamps, keywords, and links. Takes 10 minutes per video.

What This Workflow Helps You Do

• Write SEO-optimized descriptions faster
• Include the right keywords without sounding robotic
• Add timestamps that improve watch time and chapter visibility
• Create a consistent description template for all your videos

Tools You Can Use

ChatGPT: fast for generating descriptions and iterating on keyword placement.

Claude: better for longer descriptions with a natural, readable tone.

Gemini: useful for researching related keywords and YouTube search trends.

What You Need Before Starting

• Your video title
• What the video covers (bullet points or outline)
• Primary keyword you want to rank for
• 2–4 related keywords or phrases
• Timestamps (if you have them, or a rough outline to create them)
• Links you want to include (your website, related videos, social)

Step-by-Step Process

Step 1: Generate the description

Write a YouTube video description for the following video:

Video title: [your title]
What it covers: [bullet points of main topics]
Primary keyword: [main keyword to rank for]
Related keywords: [2–4 secondary keywords]
Channel niche: [what your channel is about]
Target viewer: [who is this for]

Structure the description as:
1. Hook paragraph (2–3 sentences, include primary keyword in sentence 1)
2. What viewers will learn (3–5 bullet points)
3. Timestamps section (use [00:00] format — I'll add real times)
4. About this channel (2–3 sentences)
5. Links section (leave placeholders)
6. Hashtags (5–8 relevant hashtags)

Length: 300–500 words total. Natural, readable tone.

Step 2: Optimize the first two lines

YouTube shows roughly the first 125 characters before the “Show more” cutoff. These lines need to hook both viewers and the algorithm:

Rewrite the first two lines of this YouTube description to:
- Include the primary keyword [keyword] in the first sentence
- Create enough curiosity or clarity that viewers click "Show more"
- Be under 125 characters total for both lines

Current opening: [paste current opening]

Step 3: Add timestamps

If you have your video outline or a transcript, AI can create timestamps:

Create YouTube chapter timestamps for this video.

Video duration: [X minutes]
Content sections: [paste your video outline or transcript]

Format:
00:00 Introduction
00:45 [section name]
[etc.]

Keep chapter titles short (under 5 words) and descriptive.

Step 4: Create a description template

Once you have a description you’re happy with, ask AI to turn it into a reusable template:

Turn this YouTube description into a reusable template.

Replace all specific details with [BRACKETS] for easy filling in.
Keep the structure, tone, and SEO approach.
Add a comment at the top with instructions for filling it in.

[paste your finished description]

Editing Checklist

• Primary keyword appears in the first sentence
• First two lines create curiosity or clearly state the value
• Bullet points describe specific takeaways (not vague summaries)
• Timestamps are accurate and chapter titles are clear
• Hashtags are relevant (not just popular)

Common Mistakes

Keyword stuffing. Stuffing your target keyword 10 times does not help and reads badly. Once in the first sentence, 2–3 times naturally in the body is enough.

Skipping timestamps. Chapters improve watch time and appear in Google search results for your video. Don’t skip them.

Generic bullet points. “Learn how to use ChatGPT” is not a takeaway. “The 3-part prompt structure that generates high-converting email copy” is.

No links. Every description should link somewhere. Your website, a related video, or a lead magnet. Don’t leave viewers with nowhere to go.
