YouTube Hashtag Generator: Free AI Tool for Video Tags
RecurPost’s YouTube Hashtag Generator takes a video topic and returns hashtags built for YouTube’s description field, not for Instagram or TikTok. Enter what the video covers, choose a hashtag count, and copy the list straight into the video you’re publishing — free, in the browser, no signup. YouTube shows only the first three description hashtags above your video title, and stacking too many can cause all of them to be ignored.

YouTube Hashtags Don't Work Like Instagram or TikTok Tags
A hashtag in a YouTube description behaves differently from a hashtag on Instagram or TikTok. YouTube pulls up to three hashtags from your description. It displays them directly above the video title, on both the watch page and in search results. Any hashtags beyond those three stay in the description and don’t get that top placement.
Also, YouTube has no Explore page. This feature is an Instagram and TikTok surface. Treating YouTube hashtags as an Explore-page play misreads how the platform actually works. Besides, clicking a YouTube hashtag opens a search results page for that tag, rather than a curated discovery feed.
YouTube Caps How Many Hashtags It Will Honor
YouTube also caps the number of hashtags it will honor. YouTube ignores all hashtags on a video when the title and description contain roughly 60 hashtags in total. This includes the three hashtags that would normally appear above the title.

A different mechanic entirely — no above-title display and no YouTube-style 60-tag ceiling
For example, an agency posting a long-form video and a same-day Short from one shoot needs three precise hashtags for the above-title slot on each upload. It also requires a broader set lower in the description, without tripping YouTube’s roughly 60-hashtag ceiling.
When the Generator Fits, and When It Doesn't
RecurPost’s YouTube Hashtag Generator fits creators or agencies that require a fast, credible hashtag list for a specific video. It is an ideal fit for an agency that manages several client channels and tags multiple uploads a week.

When it doesn't
Channel SEO strategy
Guaranteed views
Tags-field entries
However, RecurPost’s YouTube Hashtag Generator doesn’t fit as a stand-in for channel SEO strategy. A hashtag list won’t fix a video that is missing a strong title or a well-researched description. Plus, it cannot guarantee views or subscribers. The generator also will not fill YouTube Studio’s Tags field, which is a separate input from description hashtags.
For instance, a new channel posting weekly can run the generator before every upload as a small, repeatable step. Also, an agency managing twelve client channels can build it into a standing pre-scheduling routine for every video going out that week.
However, a well-tagged video that never goes out on schedule still won’t perform. This makes scheduling the next logical step after preparing the video. RecurPost’s YouTube scheduling keeps client channels publishing consistently once the description and tags are set.
Where the Hashtags Go in Your Description
Start by entering the topic, picking a count, and generating the list. Copy the top three hashtags into the very start of your description so they’re first in line for the above-title display. Paste the rest of the list below them.
How RecurPost's YouTube Hashtag Generator Works
RecurPost’s YouTube Hashtag Generator requires just one simple input about your video. Enter your video’s topic, working title, or keywords to get optimized hashtags instantly.
Enter your video topic
Type the video's topic, a working title, or a few keywords into the generator.
Pick a hashtag count
Choose a count between 10 and 15.
Get your list
The generator returns a list formatted for YouTube's description field.
Copy and use
Copy the list straight into the description of the video you're publishing.
RecurPost’s generator is completely free and requires neither a signup nor a credit card. It lets you regenerate the list as many times as you want until it fits the video.
For instance, a freelancer uploading a client’s weekly YouTube Shorts about a home workout routine can type “10-minute home workout, no equipment” into the generator. The tool creates a fresh hashtag list in seconds. As a result, they do not have to reuse the same five tags for every upload.
RecurPost’s free social media tools cover more than hashtags. The hashtag generator hub handles nine other platforms, from Instagram to LinkedIn, making it useful for a client video that goes out everywhere at once.
Turn Your Hashtag List Into a Scheduled YouTube Post
A hashtag list is one step in publishing a video, not the entire process.
For example, a social media manager managing six client YouTube channels can generate hashtag lists for the week’s uploads in one sitting. Queuing each video in RecurPost’s calendar for its respective channel makes the tagging process more efficient. This avoids repeating the same process for each individual upload.
This batch approach fits an operator who preps several client uploads before a single scheduling session.
However, this scheduling step doesn’t help agencies without a RecurPost account attached to the channel. The generator itself stays free and works standalone, but scheduling becomes available only after the video is added to the RecurPost composer.
Once the description is ready, open RecurPost’s post composer and paste your finished description into the YouTube post you’re building. You can then schedule the post for a later date, or publish it immediately, through RecurPost’s YouTube scheduler.
Description Hashtags vs. YouTube Studio's Tags Field
Description hashtags
Hashtags on YouTube live in the description. RecurPost's generator produces description hashtags, and YouTube displays the first three directly above the video title.
YouTube Studio's Tags field
The Tags field is a separate metadata field you fill in when you upload a video. It doesn't come from description hashtags, and the two do not substitute for each other.
YouTube Hashtag FAQs
What does RecurPost's YouTube Hashtag Generator actually produce?
The generator takes a video topic or a few keywords and returns 10 to 15 hashtags formatted for YouTube’s description field. Copy the list, paste it into your description, and edit any tag that doesn’t match the video’s actual content.
How many hashtags does YouTube show above my video title?
YouTube pulls the first three hashtags from your description and displays them directly above the title, both on the watch page and in search results. Hashtags past the third stay in the description without that placement.
Can I use this generator for YouTube Shorts?
Yes. The same hashtag rules apply to Shorts. YouTube reads hashtags from the description and surfaces the first three above the title, the way it does for long-form videos.
Does this tool fill in YouTube Studio's Tags field?
No. YouTube Studio’s Tags field is separate metadata you enter during upload, and it doesn’t come from description hashtags. RecurPost’s generator produces hashtags for the description, not Tags field entries.
Is the YouTube Hashtag Generator free to use?
Yes. RecurPost’s YouTube Hashtag Generator is free, runs in the browser, and doesn’t require a signup or a credit card. And it lets you regenerate the list as many times as you need.
How do I get generated hashtags into a video RecurPost schedules?
Copy the finished hashtag list into the description of the YouTube post you’re composing in RecurPost, then schedule or publish that post to the connected channel from RecurPost’s calendar.
