Enter a topic or paste your title and get a ranked hashtag set, split into broad reach tags and niche tags that actually describe your video.
This one needs real processing — transcription, or a video render — so it runs in the app rather than in your browser tab. Free tier: 10 generations per day.

How It Works
A topic, a title, or a line of description. Anything that says what the video is about.
Tags come back split into broad ones for reach and niche ones for relevance.
YouTube shows the first three above your title and counts a maximum of fifteen. More than that and it ignores all of them.
Hashtags on YouTube go in the description or the title, and the first three from the description appear above your video title as clickable links. Each one opens a feed of videos using the same tag — which is the entire mechanism by which a hashtag can bring you a viewer.
There is a hard rule worth knowing: use more than fifteen hashtags on a video and YouTube ignores every one of them. Not the excess — all of them. Stuffing the description is not a grey area that slightly underperforms; it is a switch that turns the feature off.
The useful strategy is a mix. One or two broad tags put you in a large feed where you are competing with everything. Two or three specific tags put you in a much smaller feed where a video like yours is actually what someone is looking for. Broad tags are lottery tickets; niche tags are where the realistic click comes from.
Why Use This Tool
The set is split so you can deliberately take some of each rather than fifteen variations on one idea.
Sized for the three that display and the fifteen that count.
Feeding it a clip transcript produces tags that match what was actually said, not just the topic label.
Ten generations a day without an account.
Tuned for Shorts rather than generic YouTube tagging.
Take what fits and drop what does not. A tag that does not describe your video does nothing for you.
Three to five. The first three in your description display above the title, and YouTube ignores all hashtags on a video that carries more than fifteen.
Modestly. They make your video findable in hashtag feeds and help categorise it. They are a small factor next to retention and click-through rate, and no tag set rescues a clip nobody watches through.
The description. Tags placed there appear above your title automatically, which is cleaner than writing them into the title and eating characters you need for the hook.
It is no longer required — YouTube identifies Shorts by aspect ratio and duration. Including it does no harm and is still common practice.
For a consistent niche, a stable core set makes sense. Reusing tags that do not describe a particular video is worse than leaving them off.
Fifteen, and it is a cliff rather than a slope. Exceed it and YouTube disregards every hashtag on the video.
Tagging is the last five percent of publishing. ShortsHero handles the other ninety-five — finding the moment, reframing it vertically, captioning it, and exporting at platform spec.
