YouTube Description Generator

Type what your video is about. The free template writes your opening and ask, holds your chapters, links and hashtags, and checks them against YouTube's rules. Or sign in with Google and let AI write three.

How to Use the YouTube Description Generator

Four steps, all in your browser. The template sends nothing anywhere.

1. Type your topic

   Say what the video is about in a few words, then pick the kind of video. Your topic fills in the opening.

2. Pick the parts you want

   Opening, chapters, links, an ask and hashtags start on. Add key points, credits, resources or a disclaimer with one tap.

3. Write each part

   Write your opening, add chapter times and paste your links. Move any part up or down to change the order.

4. Check it, then copy it

   The preview shows it the way YouTube does. Fix what the checks flag, copy it and paste it into YouTube Studio.

The First 150 Characters Are Everything

Viewers see only the first few lines until they press more. YouTube gives no exact count, so 150 characters is a safe length to aim for.

• Lead with your topic: use the words people type into search, in your first sentence.
• Say what they get: one clear promise, like a recipe in 10 minutes or the fix for one error.
• Skip the hello: "Welcome back to my channel" spends the only part most viewers see.

YouTube Description Template: What Goes in Each Part

A full description can run to 5,000 characters. Most good ones use five parts.

• Opening: what the video is about, in search words, in one or two sentences.
• Chapters: times with names so viewers can jump. Start at 0:00, add at least 3 in order, each 10 seconds or longer.
• Links: your other channels, your website, or a product you mention in the video.
• One ask: subscribe, comment or watch next. One clear ask beats five small ones.
• Hashtags: 3 to 5 that fit. YouTube can show up to 3 by your title.

Add credits for music you used, sources for facts, and a disclaimer for affiliate links or sponsors. Build chapters from your edit with the Chapter Generator.

YouTube Shorts Descriptions: Different Rules

Viewers see a Short's description only if they open it, so keep it short and useful.

• One line: say what happens in the Short, in the words people search.
• Hashtags: 3 to 5 that fit the topic, the same rules as long videos.
• No links: links in Shorts descriptions stopped being clickable on August 31, 2023.

Template or AI: Which to Use

Both are free. Pick the one that fits how much you already know.

• Fill a template: no sign-up and no limit. Best when you know your chapters and links. Nothing leaves your browser.
• Write it with AI: three different descriptions from your topic, tone and search words. Free with a Google sign-in, a few times a day.

Either way, read it before you post. You know what is in the video, and the AI only knows what you typed.

Common YouTube Description Mistakes

The checks with the preview catch the first four for you.

• Broken chapters: a first time other than 0:00, fewer than 3, or one under 10 seconds, and YouTube shows no chapters.
• Too many hashtags: over 60 and YouTube ignores every one. It also warns that too many can remove a video from search.
• Angle brackets: YouTube refuses the < and > signs, even in a heart typed as <3.
• Blanks left in: a template line still holding [game name] looks unfinished to viewers.
• A wall of keywords: a list of search words reads as spam to viewers. YouTube's advice is 1 or 2 main words, used in the title and the description.

Next, write the title with the Title Generator, then score the whole upload with the Video SEO Checker.
