About this tool
A YouTube description does several jobs at once: it tells viewers what the video is, it holds your links and chapters, and it gives YouTube text to understand the topic. This analyser breaks a description into those parts — key phrases, link count, hashtag count, timestamps and the crucial first 150 characters that appear before the more button.
How it works
The description is scanned for URLs, hashtags and timestamp patterns using pattern matching, and each is counted. The full text is then analysed for recurring two-word phrases, which shows what the description actually emphasises. Character count is compared against YouTube's documented 5,000-character limit, and the opening 150 characters are extracted separately because that snippet is what most viewers ever read.

Example

A description with chapters, two links and two hashtags
Output
Words 42 · Links 2 · Hashtags 2 · Timestamps 2
When to use it
- Checking the first line of a description earns the click on more.
- Confirming chapters are formatted as timestamps YouTube can parse.
- Auditing how many links a description carries.
- Seeing whether the description mentions the topic at all.
Tips
- Say what the video is in the first sentence — that is the part viewers see.
- Chapters need a 00:00 entry and at least three timestamps to work on YouTube.
- Keep hashtags to a handful; the first three appear above the title.
Limitations
The tool measures text; it cannot tell you whether the description helps a video perform. Timestamp detection is pattern-based, so a time mentioned in prose counts as one. Nothing here is fetched from YouTube.
Frequently asked questions
- How long can a YouTube description be?
- YouTube documents a 5,000-character limit. The counter shows your usage against it.
- Why does the first 150 characters matter?
- That is roughly what shows before the more button and in some search snippets, so it does the most work of any part of the description.
- Does keyword density in descriptions help?
- There is no published density target and stuffing hurts readability. Write for the viewer and mention the topic naturally.
