PostLink

YouTube description generator

Get a description whose first two lines work as a search snippet on their own, followed by the context, the list of what the video covers, and three hashtags that fit.

e.g. Link to the LUT pack, my Instagram, chapters at 0:00 / 2:14 / 8:40

We read your recent uploads so the results match what the channel already does.

We transcribe it and write from what is actually said. Up to 12MB; the file never leaves the run.

What a description is for

Two audiences read it: YouTube, deciding what the video is about, and a viewer deciding whether it is the right video. Both are served by the same thing — plain sentences that name the topic, the tools and the outcome, near the top.

The shape that works

  • Two opening lines that stand alone as a summary.
  • A short paragraph of context: who it is for, what it assumes.
  • A list of what the video covers, so a skimmer can self-select.
  • Links and chapters after that, where they do not compete with the summary.

What to leave out

Keyword stuffing, a paragraph about your channel, and a wall of hashtags. None of them move views, and the first can get a video demoted.

How to use the generator

  1. Describe the video: its topic, who it is for and what someone will know or be able to do after watching.
  2. Read the first two lines of the result on their own. They are what shows in search and under the video before “more”.
  3. Edit anything that is not quite true to the video, add your own links and chapters, then paste it into YouTube Studio.

Description limits and details

  • YouTube allows up to 5,000 characters; the first 100–150 are what most people see.
  • Up to three hashtags from the description appear above the title. More than fifteen and YouTube ignores all of them.
  • Timestamps starting at 0:00 in the description become chapters automatically.
  • Angle brackets are not allowed in descriptions, and links to misleading or harmful sites break YouTube's policies.

A generated description is a draft, not a finished text. The best ones keep the structure and replace the generic phrases with the specific things only you know about the video.

Questions

What should the first two lines say?

Everything that matters. Those lines appear in search results and above the "more" fold, so they carry the summary — not a greeting, not a subscribe plea.

How long should a description be?

Long enough to describe the video honestly, usually 150 to 300 words. Length itself does nothing; specific words that match how people search do.

Do hashtags help?

Mildly. The first three appear above the title, so use them as labels for the topic rather than a wall of tags. More than three and YouTube ignores all of them.

Should I put timestamps in the description?

Yes when the video has sections. Plain timestamps starting at 0:00 become chapters automatically, which gives viewers entry points and shows up in search.

Is it free?

Two runs free, then it continues on a paid plan, because each generation costs model time.
