How it works
From source material to a publish-ready description.
Hand ngram the topic or transcript, draft the description with chapters and links, then keep the rest of the upload nearby.
Add the source
Paste the topic, transcript, script, notes, or URL behind the video so the description starts from the actual message, not a generic channel blurb.
Source context ready
Draft the description
ngram writes the 125-character hook, summary paragraph, chapter timestamps, link block, hashtags, and CTA so the first 200 characters carry the primary keyword and the promise.
Description drafted
Match the channel voice
Adjust tone, swap product or affiliate links, drop hashtags you do not use, and keep the description consistent with the title and thumbnail.
Channel voice matched
Publish or keep polishing
Copy the description into YouTube Studio, or stay in ngram to fix captions, generate a thumbnail, render the final cut, and route the upload.
Ready for upload
What it can do
What the description draft includes.
Use the YouTube description generator as one slice of an upload pass, not a standalone text box.
Hook in the first 125 characters
Lead with a benefit-driven sentence that carries the primary keyword early, so the snippet that shows above the fold earns the click.
Chapter timestamps from 0:00
Draft chapter cues starting at 00:00 with keyword-rich titles so YouTube can surface Key Moments and viewers can jump straight to the part they want.
Links, CTAs, and hashtags
Add product, newsletter, affiliate, and next-video links plus a closing CTA and three relevant hashtags, without turning the description into a tag dump.
Reuse the transcript for captions
When the description pulls from a transcript, the same source can power burned-in captions so the spoken words and the metadata stay aligned.

Move from finished description into Image Lab when the upload still needs a branded thumbnail that echoes the title and hook.
