AI Hashtag Generator
Generate relevant hashtags for social media with AI
The AI hashtag generator turns a post idea into 30 hashtags for one network: paste your text, choose Instagram, Twitter/X, TikTok, LinkedIn or YouTube, pick a tone and press Generate Hashtags. They arrive in three groups — high reach, medium reach and niche — so an Ethiopian pour-over launch gets #SpecialtyCoffee, #EthiopianCoffee and #SmallBatchCoffee to copy or download.

About AI Hashtag Generator
The AI Hashtag Generator reads up to 5,000 characters of caption, script notes or a one-line topic and returns 30 hashtags written for one platform. Your choice in the Platform menu — Instagram, Twitter/X, TikTok, LinkedIn or YouTube — and in the tone menu — Professional, Casual, Friendly, Formal or Creative — travels with the text, so the same brief yields #PourOverCoffee for an Instagram launch and #DataEngineering for a LinkedIn product announcement.
Nothing is looked up in a hashtag database. A language model writes the tags from the meaning of your text, sorts them into high-reach, medium-reach and niche bands, usually adds a short note beside each tag and closes with a few usage notes. A run usually takes between five and fifteen seconds; the model that answered is printed under the panel, together with the word and character count of the whole block.
Two limits are worth knowing before you paste. The bands are the model’s estimate, not a measured post count; the tool has no live link to any network, so it cannot tell you what is trending today, and the post counts it sometimes prints beside a tag are invented. The platforms are also stricter than 30: Instagram limits a post or reel caption to five tags, and YouTube’s help pages say a video carrying more than 60 hashtags has all of them ignored. Treat the 30 as a shortlist to cut down, not a block to paste whole.
Your text leaves the browser only when you press Generate Hashtags, and only to this site’s own /api/ai/tool endpoint, which passes it to the model and sends the tags back. Nothing is saved on the page: reloading empties both the input box and the result panel.
Use Cases
How to use
Paste the caption, post idea or topic you want tags for into the Input Text box, which takes up to 5000 characters with a counter under it.
Pick the network under the Platform label: Instagram, Twitter/X, TikTok, LinkedIn or YouTube; that choice is sent with your text so the tags suit the network.
Choose a tone beside the Generate Hashtags button: Professional, Casual, Friendly, Formal or Creative.
Click Generate Hashtags; the button turns into a spinner showing the elapsed seconds while the 30 tags are written.
Read the Generated Hashtags panel, where the tags come grouped as high reach, medium reach and niche, with a word and character count below.
Click Copy to take the whole set, the .txt button to download it, or Regenerate for a fresh batch.
Pro Tips
- Change the Platform menu and press Generate Hashtags again before you rewrite anything: the same coffee paragraph returned #CoffeeAddict and #CoffeeOfTheDay under Instagram and #CoffeeBusiness and #CoffeeIndustry under LinkedIn, so switching networks costs one click.
- The tone menu changes the tags themselves, not just the notes beside them: with the same paragraph, Professional returned #FreshRoastedCoffee and #NewCoffeeRelease, while Creative returned #CoffeeAndChill and #ThisWeek’sRoast.
- Keep the Input Text under about 4,800 characters even though the counter allows 5,000: the page wraps your text in an instruction sentence before sending it, and the request is refused once the combined length passes 5,000.
- Press Regenerate rather than editing the text when a list feels flat. It clears the panel and asks again with the same text, platform and tone, and the second list usually keeps the obvious tags while swapping several niche ones.
- Use the .txt button rather than Copy when you are collecting tags for a batch of posts: Copy puts the whole panel, group headings included, on the clipboard, while each download keeps one run in a file of its own.
Troubleshooting
Generate Hashtags is greyed out and clicking it does nothing.
The button stays disabled until the Input Text box holds something other than spaces. Type or paste a topic — three words is enough — and the button turns pink and becomes clickable.
A long caption always ends in a red box reading “Network error. Please try again.”
That is the 5,000-character ceiling. The page wraps your text in a 194-character instruction before sending it, so 4,900 characters in Input Text become a 5,094-character request, which the endpoint refuses before the model sees it; the page cannot read that reply and falls back to its generic network message. Trim the box to about 4,800 characters — the counter under it turns red past 4,500 — and press Generate Hashtags again.
A red box reads “Rate limit exceeded. Please wait a moment.”
You have asked for too many lists inside one minute. The endpoint accepts ten generations a minute from one address and answers the eleventh with exactly that sentence. Wait about sixty seconds, then press the Retry button inside the red box. A second, site-wide limit of thirty requests a minute answers with an HTML page instead of JSON, and the box then shows the generic network message; one minute of waiting clears both.
The result panel shows ### and --- as plain text between the groups.
The model replies in Markdown and the panel converts only bold and italics, so heading marks and separator lines stay visible. They are not part of the hashtags: copy the block or download the .txt file and keep the lines that start with #.
The hashtags come back in a different language from the page.
The page sends its language code, so the commentary and the group headings follow the page — but the tags follow the text you paste. A German caption on the German page returned #KaffeeLiebe and #ÄthiopischerKaffee; the same brief written in English returned German commentary over a mix that included #CoffeeLovers, #SpecialtyCoffee and #BaristaLife. Write the caption in the language you want the tags in.
Frequently Asked Questions
Five at most. Instagram's statement, reported by Social Media Today in December 2025, is that it “will gradually update the number of hashtags that you can include in a caption for a reel or post to five”, because fewer targeted tags work better than many generic ones. The generator still returns 30 so you have something to choose from: take one broad tag from the high-reach group for context and four from the medium-reach and niche groups that describe what is actually in the post.
No spaces: a hashtag is one unbroken token, so a space ends it — which is why every tag the generator returns is a single word. Capital letters are fine and the tool puts them inside the tag, as in #SmallBatchCoffee and #PourOverCoffee from an Instagram run, so a long tag is still readable at a glance. It occasionally returns a tag carrying an apostrophe or an accent, so read the block before you paste it.
YouTube's help page on using hashtags for video search says that if a video or playlist has more than 60 hashtags, every hashtag on that content is ignored, and that out of all the hashtags in the description up to three of the most engaging ones appear beside the video title. Choose YouTube in the Platform menu and treat the high-reach group as the shortlist for those three.
No. It has no live connection to Instagram, TikTok, X or YouTube and cannot count posts, so “high reach”, “medium reach” and “niche” are the model’s estimate from training, not a measurement taken today. It will sometimes even print a post count beside a tag — that figure comes from the model, not from the network. Search each tag you intend to keep inside the app itself before publishing; that is the only place the current volume, and any restriction on a tag, is visible.
Instagram's published statement covers the caption: the number of hashtags “that you can include in a caption for a reel or post” is moving to five. It says nothing about tags placed in a comment, so treat the first comment as a matter of house style rather than a way to buy extra slots. The generator does not decide for you — copy the block, keep the tags you want and paste them where they read best.
It is free, with no sign-up, no API key and nothing to install. The page posts your text to this site's own endpoint, which calls the language model and returns the tags. That endpoint accepts ten generations a minute from one address; the eleventh comes back as a red box reading “Rate limit exceeded. Please wait a moment.” Wait about a minute and press Retry.
They still exist, but there is much less room for them. Instagram's own statement, reported by Social Media Today in December 2025, moves the cap for a reel or post caption to five, down from thirty, on the grounds that “fewer (up to 5) more targeted hashtags” beat many generic ones. That makes the choice matter more than the count, which is what the three reach groups are for: one broad tag, the rest specific.
Yes. Choose Instagram in the Platform menu: the generator writes for the network you select rather than for a specific format, so a Reel and a feed post receive the same candidate list. If the same clip also goes to TikTok and to YouTube Shorts, run the brief again with those platforms selected — each network produces a noticeably different vocabulary.
Choosing LinkedIn in the Platform menu changes the vocabulary, and that is the part this page can show you. The same coffee paragraph came back with #CoffeeAddict and #CoffeeOfTheDay on Instagram, and with #CoffeeBusiness, #CoffeeIndustry and #CoffeeInnovation on LinkedIn. Whether those tags earn reach is not something the tool can measure — it has no connection to LinkedIn — so treat the list as vocabulary, not a forecast.
The generator does not set the number. Pick TikTok in the Platform menu — the choice is sent with your text — and you still get 30 tags in three reach groups, from which you choose by hand. Two or three broad tags from the high-reach group plus a few from the niche group make a workable shortlist, and every tag you add eats into the caption. Press Regenerate for a different set with the same text and tone.
