Write a complete YouTube description from your real video

Paste the script and get a structured description with an opening, a summary, your chapters and your links. Anything it cannot know becomes a checklist item instead of a convincing invention.

The current or working title.

0/150

This is the source everything is grounded in. A thin outline produces a thin, generic description.

0/12000
0/240
0/500

One per line, as 'Label https://...'. Up to eight, and they are copied through exactly as written. No link is ever generated.

0/900

One per line, as '0:00 Chapter name'. The first must be 0:00 and each must be later than the last. Timestamps are never guessed.

0/1200

Used exactly as you write it. The tool will not infer a sponsorship or decide what disclosure the law requires.

0/600

Used naturally, at most twice, and only where the script actually supports it.

0/100

Up to five factual topic terms. At most five hashtags are ever added.

Use public, non-confidential information only. Your inputs are sent to our AI provider to generate the description and are not included in product analytics.

Your description will appear here in sections you can edit, with anything still missing listed separately.

Why this one

What this tool gets right

It never invents a link or a timestamp

Chapters and links are assembled from what you typed, character for character. The model writes prose and nothing else, because a plausible-looking URL in published metadata is the worst thing one of these tools can do.

Missing details stay visible

No chapters, no destination for your call to action, a sponsorship mentioned with no disclosure wording. Each one becomes a checklist item that sits outside the description and is never copied with it.

Grounded in the actual script

The opening and summary are written from the transcript you paste, not from the title. Every number, name, offer and claim has to trace back to your source.

Editable section by section

Rewrite the opening, tighten the summary, drop a hashtag. Copy the whole description or just one section, and the character count updates as you go.

How it works

Three steps, about thirty seconds

01

Paste the real source

The title, the script or transcript, and who the video is for. A detailed outline works; a one-line topic produces exactly the generic description you were trying to avoid.

02

Add what only you know

Your links, your chapter timestamps, and any disclosure wording. All three are copied through exactly and none of them are ever generated.

03

Clear the checklist, then paste

Work through anything the tool flagged as missing, edit any section that is not quite right, and copy the description into YouTube.

What belongs in a useful description

A useful description helps the right viewer understand the video and take the next relevant action, and makes the content easier to scan without claiming more than the video delivers. This description generator for YouTube organises your source into six possible parts: an opening that names the video and gives a reason to watch, a summary grounded in the script, real chapter timestamps when you supply them, confirmed links and a supported call to action, disclosure wording you provide, and a small set of hashtags. The structure is consistent, but not every part has to appear. A video with no links should not receive invented URLs.

Why source-grounded beats topic-grounded

Generic generators work from a topic alone, which makes it easy to produce smooth copy introducing facts, benefits or links the creator never mentioned. The output reads well and quietly misrepresents the video. Starting from the real title and the spoken source changes what is possible: names, numbers, offers, relationships and destinations have to trace back to your input. The result may still need editing, but the operational gaps stay visible instead of disappearing behind plausible wording.

Check the description before you publish

  • The generator uses only the text and settings you submit. It does not watch, upload, transcribe or inspect a video.
  • It does not connect to YouTube, inspect a channel, read analytics or publish metadata.
  • It does not fetch or verify your links. Check that every one works.
  • It never guesses timestamps. Add chapters only from the finished video.
  • It can preserve disclosure facts and prompt a review, but it cannot determine legal or platform requirements.
  • It cannot verify claims, rights, trademarks, policy compliance or accuracy outside your source.
  • Hashtags and keywords do not guarantee ranking, reach, clicks, views or engagement.
  • The 4,500-character ceiling is this tool's working limit, not a statement of YouTube's current limit.
  • Do not enter confidential, private or internal information.

Questions, answered

Yes. Generate, edit and copy the complete description without an account. A fair-use limit caps how many runs you get in an hour and resets on its own.
An opening promise, a summary, your supplied chapters, your supplied links with a call to action, any disclosure wording you provided, and up to five restrained hashtags. Missing details go in a separate checklist that is not copied with the text.
No. It does not fetch, watch or transcribe anything. Paste the real script, the transcript, or a detailed outline of what is actually said so the description stays tied to the source.
No, and that is deliberate. It formats and order-checks timestamps you supply, but it never guesses one. If you add no chapters, the checklist reminds you to take real timestamps from the finished video.
Yes. Add up to eight full https links and choose a viewer action. Only your destinations are used. If your chosen action needs a link you did not supply, the CTA is left out of the copied text and flagged in the checklist instead.
It preserves disclosure wording you provide, exactly as written, and can remind you to review whether one applies. It does not infer a relationship and it cannot tell you what the law or the platform requires.
Up to five unique ones, drawn from your title, script, target phrase or topic terms. It will return none rather than pad, and it makes no claim that they affect reach.
Nothing here is a ranking guarantee. This YouTube description maker uses your target phrase naturally, only where the script supports it, and keeps hashtags restrained. It has no access to live search data.
