How much of your video description does a viewer ever see? Two lines, then a "show more" nobody taps. So what goes in those two lines decides whether the description does any work at all, on YouTube and everywhere else.
Short answer: The Video Description Generator is a free EizTools tool that writes video descriptions for YouTube, TikTok, Reels and LinkedIn, with keywords, hashtags, chapters and a closing call to action shaped for the platform you chose.
What is Video Description Generator?
It is a writing tool for the box under the player. You describe the video, and the Video Description Generator writes the description: a front loaded opening, a fuller explanation for anyone who expands it, and the extras each platform rewards, such as chapters or hashtags.
Six platforms
A YouTube description and a TikTok caption are different lengths with different habits. Pick one and the output follows it.
Chapters and timestamps
Switch on chapters and the description carries a timestamp list, which also creates the chapter bar on the player.
Keywords worked in
The SEO toggle places the terms people search for into sentences rather than a keyword block.
The First Two Lines Carry Everything
Those two lines appear in search results, in the collapsed description, and often in a share preview. They should say what the video shows and who it is for, using the words a viewer would type. Everything below the fold is for the people who already decided to watch, which is where links, chapters and credits belong.
How Does Video Description Generator Work?
Describe the video in the prompt box, with the audience in it: ten minute tutorial showing complete beginners how to set up a home recording studio for under three hundred pounds, covers interface, mic choice, treatment on a budget, ends with a gear list.
Choose an engine and generate. The description comes back in the result card with a live word count, which tells you at a glance whether it fits the platform. Copy it into your upload page, or save it as a text file. The history panel below the result is how you keep a YouTube version and a Reels version apart.
Platform, Video Type And Extras
| Platform | What changes | Extras worth switching on |
|---|---|---|
| YouTube | Longer copy, search terms, room for links | Chapters and SEO keywords |
| TikTok | Short, spoken, hook led | Hashtags only |
| Instagram Reels | Caption style, more personal | Hashtags and a CTA |
| Context first, professional framing | CTA, no hashtag stack |
Video Type changes the structure more than tone does, since a tutorial needs steps and a review needs a verdict. Point of View on Second Person suits how to content because it addresses the viewer directly. Output Length on Normal fits YouTube, while Short is closer to what a Reels caption needs.
Caution Do not paste in thirty hashtags because the tool can produce them. Platforms treat obvious tag stuffing as spam, and a description crowded with tags reads badly to the humans who do expand it. Five relevant tags beat thirty generic ones.
What Costs You Views
- Opening with "In this video I will" instead of the subject itself
- Leaving the timestamps out on anything over five minutes
- A description written for the algorithm that tells a person nothing
- The same copied text under every video in a series
- Links buried below a wall of hashtags where nobody scrolls
You can run this as often as you like on EizTools without an account or a credit counter, which suits a job you repeat with every upload. The AI model family is chosen per generation from the selector. For recorded sessions and online events there is the Webinar Description Generator, and short posts around a launch can be drafted with the Facebook Caption Generator.
Frequently Asked Questions
How long should a YouTube description be?
Long enough to be useful, usually two hundred to three hundred words, with the important part in the first two lines. Everything after that serves viewers who expanded it deliberately.
Does it create the chapter timestamps?
It formats them, but the times have to come from you. Give it your section times in the brief and check each one against the video before publishing, since wrong chapters are worse than none.
Can I use one description across platforms?
You can, but it performs worse. Run the Video Description Generator once per platform, because the length, tone and hashtag habits differ enough to matter.
Will it add my links?
It leaves a place for them and can write the surrounding line, but the URLs are yours to paste in. Nothing is looked up, so no link appears unless you supply it.
The description is the part of a video most people write last and fastest. Spend the time on the opening two lines, add real chapters, keep the hashtags few and relevant, and write a fresh one for each platform instead of pasting the same block everywhere.
