YouTube Description Generator

Four ready-to-paste video descriptions from the title — with the two lines that show before “...more” marked on each.

Four per press. Your answers are sent to our generator — the video is not, and the descriptions are not stored.

How it works

How to write a YouTube description?

  1. Paste the video title

    The title you are publishing with — the first two lines repeat its main keyword.

  2. List what happens

    A few comma-separated points, and your channel name if you want it in there. Pick a tone or leave it mixed.

  3. Pass the quick check

    A one-tap Turnstile check. It usually clears itself.

  4. Copy, fill, publish

    Four descriptions in different shapes. Copy one, swap [link] for your URLs, set the timestamps, paste into Studio.

Anatomy

What goes in a YouTube description

Top to bottom, the parts a good description has — and the one part that actually gets read.

The first two lines

Roughly 150 characters show under the player and in search. Say what the video is and use the title’s keyword — this is the only part most viewers ever read.

The summary

Two or three short paragraphs on what happens and who it is for. Written for a person, not a crawler.

Timestamps

Lines like 0:00 Intro, 1:20 Week one. Three or more in order, starting at 0:00, and YouTube turns them into chapters.

Links

Socials, the thing you mentioned, the newsletter. One per line — the generator leaves [link] where each goes.

The call to action

Subscribe, comment, or watch the next video. One plain line, not three.

Hashtags

Two or three on the last line, no more than 15 in total or YouTube ignores them all. The first three show above the title.

Questions

Frequently asked questions

How does it write the descriptions?

From the title, key points, channel name and tone, it writes four descriptions in different shapes — a summary, a what-you-will-see list, a story-led one and a timestamps skeleton — and marks where “...more” cuts each one.

How long should a YouTube description be?

The limit is 5,000 characters; 500 to 1,500 is plenty. What matters most is the first 150 or so — that is what shows before “...more” and in search — so front-load the point.

Do descriptions help with search?

Yes, more than tags do. YouTube reads the description to understand the video, and the first lines appear in search results. Use the title’s keyword naturally in the opening, don’t stuff it.

How do timestamps become chapters?

List at least three timestamps in the description, in order, starting with 0:00, each at least 10 seconds apart, and YouTube turns them into chapters automatically.

Can I put links in the description?

Yes — paste full URLs and YouTube makes them clickable (some channels need to be verified for external links). The generator writes [link] placeholders so it never invents a URL.

Can I edit the description after publishing?

Any time, in YouTube Studio → Content → the video → Details. Changes go live within a few minutes.
