Generate a complete YouTube description with intro, body, CTA, hashtags, and chapter placeholders.
2-4 sentences describing what the video covers, who it's for, and any specific angle. Specificity in the brief = specificity in the output.
The model weaves it into the call-to-action naturally if provided. Skip if you're early-stage and the channel name is still in flux.
The model returns a structured description: 1-2 line hook (these are the only 120 chars YouTube shows in search), 2-3 paragraph body, chapter placeholder, CTA, and 3 hashtags at the end.
Drop in your real chapter timestamps. Use our Chapter Generator to validate them against YouTube's 4 rules.
We leave room for these intentionally. Disclose paid partnerships clearly — YouTube requires it and the FTC enforces it.

Describe what's in your video, and the model produces a complete YouTube description — hook, body, chapters placeholder, call-to-action, and 3 hashtags — in seconds. The structure follows the format that performs well in YouTube's search and browse surfaces, with the strongest signal packed into the first 120 characters.
Generated descriptions are ready to paste into YouTube Studio. Drop in your real chapter timestamps where the placeholder is, add any affiliate or sponsor links after the CTA, and you're done.
Most well-performing videos have descriptions between 800 and 2,500 characters. The first ~120 characters are the most important — they show in search results and in the 'more' preview before the click. Length itself isn't a ranking factor, but a thoughtful description signals to YouTube that your video isn't low-effort.
Yes, for two reasons. (1) It's part of the signal YouTube uses to understand what the video is about — especially in the first hour after upload, before watch-behaviour data exists. (2) The first 120 characters appear in search results and influence click-through rate, which is itself a ranking signal.
It marks where to paste your timestamps. Use our free Chapter Generator to format them — paste your rough timestamps in, it validates them against YouTube's 4 rules, and gives you back the correctly-formatted block to drop in here.
Yes, after the call-to-action. Most creators put them in a 'Links' section below the chapters. Disclose paid partnerships clearly — YouTube requires it and FTC enforces it. The model intentionally leaves space for these so you can paste your own.
YouTube only displays the first 3 hashtags from a description above the title. Beyond 3 they just count as text. More than 15 total hashtags can flag your video for hashtag abuse and demote it.
After. The model produces a sharper description when you describe what's actually in the final video — including any tangents or unexpected segments. Pre-write a working title and tags before filming, save the description for the upload step.
Yes. YouTube monetizes based on the video itself and the channel's overall standing — not on whether the description was AI-written. As long as the description accurately describes the video and doesn't violate community guidelines, you're fine.
Use these together for a complete upload checklist.
