YouTube Description Generator

Use Tella’s free AI YouTube Description Generator to turn a video title, keywords, and optional transcript into a first draft. It works without a login, so you can generate a description and edit it before publishing.

How to write a good description for YouTube?

1. Add transcript

If you have a transcript for your video, paste it into the YouTube Description Generator. A transcript gives the generator specific topics and details to work from.

A transcript helps the AI create a more detailed and accurate description. If you don't have one, skip this step.

2. Video name

Enter the title of your video to help the AI understand what your video is about.

3. Keywords (optional)

Add keywords that are relevant to your video. This step is optional but can help your video show up in search results. 

4. Tone of voice

Choose a tone that suits your brand and style. You can opt for casual, formal, or enthusiastic tones, for example. 

5. Emojis

Decide if you want to use emojis in your description. They can sometimes make it more engaging, especially if your audience is on the younger side. 

6. Generate

Click Generate, then review the draft against your video. Correct any details the generator inferred, move the most useful summary into the first lines, and add links or credits that were not in your inputs.

What to include in a YouTube description

YouTube allows up to 5,000 characters, but a useful description does not need to fill the limit. Make the opening lines understandable before the viewer expands the description, then add the details that help someone navigate or act on the video.

A practical structure is:

1. Summary: Explain what the viewer will learn or see in one or two sentences.
2. Chapters: Add timestamps for longer videos, starting with 00:00.
3. Resources: Link to products, sources, or related videos mentioned on screen.
4. Call to action: Give the viewer one clear next step, such as subscribing or visiting a related guide.
5. Credits and disclosures: Credit collaborators and disclose sponsorships or affiliate links where required.

Treat the generated text as a draft. Keep claims accurate, remove repetition, and only use keywords where they describe the video naturally.

Why it’s useful

• Faster first draft: Start from your title, keywords, and transcript instead of a blank page.
• Grounded in your video: A transcript helps the result reflect the topics you actually covered.
• Editable tone: Choose a tone, then revise the output so it still sounds like your channel.

How to get the best results

• Use specific keywords: Add phrases that accurately describe the video instead of broad or unrelated terms.
• Consistent tone: Choose a tone of voice that matches your other videos. This helps maintain a consistent brand image across the board.
• Experiment with emojis: Try using emojis to make your descriptions stand out from the crowd and catch your audience’s attention.
