RecurPost YouTube Hashtag Generator: Free AI Tool for Video Descriptions
RecurPost’s YouTube Hashtag Generator takes a video topic and returns hashtags built for YouTube’s description field. Describe what the video covers, generate the list, and copy it into the description of the video you are publishing. No login and no payment are required.
YouTube treats hashtags differently from a caption-led network: it picks up to three of a description’s hashtags to show above the video title, and a video carrying more than 60 of them has every one ignored. The generator is one of RecurPost’s free tools, and RecurPost runs a matching hashtag generator for nine other platforms.

How RecurPost’s YouTube Hashtag Generator Works
RecurPost’s YouTube Hashtag Generator asks for one input: what the video is about. Enter the topic, a working title, or a few keywords, and it returns a list formatted for YouTube’s description field.
A freelancer uploading a client’s weekly Short about a home workout can type “10-minute home workout, no equipment” and get a list in seconds, instead of reusing the same five tags on every upload.
RecurPost’s free tools cover more than hashtags, and the hashtag generator hub handles nine other platforms for a client video going out everywhere at once.
YouTube picks up to three of a description’s hashtags for that slot, choosing the ones it judges most engaging.
Add more than 60 hashtags to a video and YouTube ignores every one of them.
Twenty-two tones, from Professional and Informative to Witty, Bold, and Urgent, in five languages.
Runs in the browser, no account required.
How to Generate YouTube Hashtags in Four Steps
Using RecurPost’s YouTube Hashtag Generator takes four steps, and all four run free in the browser with no sign-up.
Describe the video
Type the video’s topic, its working title, or a few keywords. A phrase is enough.
Open Optional fields
Optional fields adds a keyword to carry into the set, a language (English, French, Spanish, German, or Italian), and a tone. Twenty-two tone presets are available.
Generate the list
RecurPost returns a list formatted for the description field in the results box below the form.
Trim the set before pasting
One button copies the set. Paste it into the description and cut any tag that does not match the video: YouTube picks up to three of whatever you leave in, so a short, accurate list is what makes that pick a good one.
A social media manager running six client channels can prepare the week’s lists in one sitting and queue each video on its own channel, instead of handling the tagging upload by upload.
Where a YouTube Hashtag Set Does Not Transfer
The YouTube Hashtag Generator is one of eight free tools published alongside RecurPost’s social media scheduler, each built to prepare a post before it is scheduled. RecurPost runs a matching hashtag generator for nine other platforms, because a list written for a video description rarely suits another network unchanged. The four below differ from YouTube most sharply. Bluesky and Google Business Profile run their own generators as well, and the Hashtag Generator hub lists all ten side by side with the limit each one works to.
TikTok reads the first five hashtags in a caption and ignores the rest, so a Short’s TikTok cut wants a five-tag caption set rather than a description list.
Threads applies a single topic tag per post, and every other hash-prefixed word is plain text. Nothing about a description list carries over.
LinkedIn reads tags as topic labels at the end of a post and treats more than five as stuffing, so the LinkedIn generator pairs one broad discipline tag with niche ones.
Pinterest publishes no hashtag limit and reads the Pin description as language, so the Pinterest generator writes search-phrase tags rather than tags competing for an above-title slot.
Checking the destination before reusing a set fits any agency or freelancer running two or more platforms per client. A freelancer publishing only to YouTube can stay on this page and skip the rest.
Turn a Hashtag List Into a Scheduled YouTube Post
A hashtag list is one step in publishing a video, not the whole job. Paste the finished description into the YouTube post you are building in RecurPost’s composer, then schedule it or publish it immediately through RecurPost’s YouTube scheduler.
Batching fits an operator prepping several client uploads before one scheduling session. The scheduling half needs a RecurPost account attached to the channel; the generator itself stays free and works on its own. RecurPost’s scheduling tools keep the channels publishing once the description and tags are set.
No credit card. One composer covers a full client mix, so a generated hashtag list moves into a scheduled upload rather than into an intermediate spreadsheet.
How YouTube Hashtags Behave, and What They Are Not
YouTube displays up to three of a video’s description hashtags directly above the video title. YouTube chooses which three, by the tags it judges most engaging, so the set you paste in decides what it has to choose from rather than which three win the slot. Ordering the list does not override that choice.
YouTube ignores every hashtag on a video, including the three that would otherwise show above the title, once that video carries more than 60 of them. YouTube also has no Explore page: clicking a hashtag opens a search results page for that tag, not a curated discovery feed.
Description hashtags are not YouTube Studio’s Tags field. The Tags field is separate metadata entered during upload, and the two do not substitute for each other. A hashtag list also will not fix a video missing a strong title or a well-researched description.
Hashtags Are Not a Description or a Title
Hashtags label the video and feed the above-title slot. That is this tool’s only job.
The description carries the copy the tags sit inside. RecurPost’s YouTube post generator writes that one.
The title is what those hashtags sit above. RecurPost’s YouTube title generator handles those.
RecurPost splits the three jobs across separate free tools, each running under the same no-sign-up rule, and you can reach the full set from RecurPost’s free tools hub.
YouTube Hashtag Generator FAQs
What does RecurPost’s YouTube Hashtag Generator produce?
The generator takes a video topic or a few keywords and returns hashtags formatted for YouTube’s description field. Copy the list, paste it into the description, and edit any tag that does not match the video’s actual content.
How many hashtags does YouTube show above my video title?
Up to three. YouTube chooses them from all the hashtags in the description, taking the ones it considers most engaging, so where a tag sits in the list is not what decides it. Keep the list short and accurate rather than front-loading three tags.
Can I use this generator for YouTube Shorts?
Yes. A Short has a description field like any other upload, and the generator writes for that field. YouTube’s hashtag rules, up to three chosen for the above-title slot and every tag ignored past 60, are documented for videos generally, Shorts included.
Does this tool fill in YouTube Studio’s Tags field?
No. YouTube Studio’s Tags field is separate metadata entered during upload, and it does not come from description hashtags. RecurPost’s generator produces hashtags for the description.
Is the YouTube Hashtag Generator free to use?
Yes. RecurPost’s YouTube Hashtag Generator is free, runs in the browser, and does not require a sign-up or a credit card.
How do I get generated hashtags into a video RecurPost schedules?
Copy the finished list into the description of the YouTube post you are composing in RecurPost, then schedule or publish that post to the connected channel from RecurPost’s calendar.
