AI Social Media Post Generator
Generate engaging social media posts for any platform with AI. Includes hashtags.
This AI social media post generator writes a ready-to-publish caption with hashtags for one of five platforms. Type the subject into Post Topic, pick Twitter/X, Instagram, LinkedIn, Facebook or TikTok in the selector, and press Generate Post. A one-line LinkedIn brief about recycled-polyester daypacks came back in seven seconds as a 130-word, 999-character post carrying 14 hashtags.

About AI Social Media Post Generator
The page puts the line 'Platform: ' plus your choice in front of whatever you typed and sends the whole thing to the site's /api/ai/tool endpoint, together with a fixed instruction to act as a social media expert, write an engaging post for the given platform and topic, include relevant hashtags, and answer in the language of the page. Post Topic accepts up to 5,000 characters with a live counter.
Generate Post turns into Generating... with a seconds timer, then the result appears under Social Media Post with the name of the model that answered, a word and character count, a Copy button, a .txt button saving ai-social-media-post-result.txt, and Regenerate. The platform selector steers tone and format only. Nothing checks the length against that platform's limit, so a Twitter/X post can come back far longer than 280 characters and it is on you to trim it - the character count under the result is the number to watch.
Two things are worth knowing before you publish. The model invents specifics when the brief is thin: asked about recycled daypacks it produced the claim that every pack saves 1.5 plastic bottles, a figure nothing in the brief supported. Delete any number, certification or comparison you did not supply. And the output language follows the page rather than your topic, so the English page answers in English even when the topic is written in another language.
Hashtags come as part of the post because the instruction asks for them; there is no separate field and no control over how many. The run above produced fourteen, which is a lot for LinkedIn and about right for Instagram, so expect to cut. Generation is limited to ten requests a minute from one connection, and your topic leaves the browser for this site's server and a hosted language-model provider.
Use Cases
How to use
Write what the post is about in the Post Topic box, including the angle and the audience, not just a product name.
Add any constraint as plain text in the same box, for example maximum 240 characters, three hashtags, no emoji.
Pick the network in the selector: Twitter/X, Instagram, LinkedIn, Facebook or TikTok.
Click Generate Post and wait while the button reads Generating with the elapsed seconds.
Read the Social Media Post panel and check the character count underneath against the limit of the network you chose.
Press Copy or the .txt button to save it, or Regenerate for a different version of the same topic.
Pro Tips
- The platform selector is prepended to your text as 'Platform: X'. It changes tone and shape, not length: nothing here enforces Twitter/X's 280-character limit, so read the character count under the result before posting.
- Strike out every fact you did not supply. In one run the model claimed each pack saves 1.5 plastic bottles, which was nowhere in the brief; invented figures like that are the main risk in publishing this output unread.
- Ask for the hashtag count in Post Topic - 'three hashtags, no emoji' - because there is no separate control. Left alone the model tends to produce a dozen or more, which suits Instagram far better than LinkedIn.
- Give it the angle, not just the subject. 'New recycled fabric, aimed at students, proud but not preachy' produces something usable; a product name alone produces a generic announcement.
- Regenerate keeps your topic and asks again, and each run may be answered by a different model, so two attempts on the same brief differ genuinely rather than being reworded.
Troubleshooting
The panel shows a network error message instead of a post.
The request was refused, almost always because more than ten generations left your connection in the same minute. Wait a minute and press Generate Post again; the topic stays in the box, so nothing is lost.
The post is far too long for the network I chose.
The platform selector steers tone, not length, and no limit is enforced. Read the character count under the result, and add an explicit instruction such as maximum 240 characters to the topic before regenerating.
The post contains a statistic I never gave it.
The model fills gaps with plausible-sounding detail; one run invented that each pack saves 1.5 plastic bottles. Delete every figure, certification and comparison you did not supply, and put the real numbers into the topic so it uses those instead.
There are far more hashtags than I want.
The instruction always asks for hashtags and there is no control over how many, so a run can produce a dozen or more. Add the number you want to the topic - for example three hashtags only - and regenerate, or simply delete the surplus after copying.
Frequently Asked Questions
Yes, with no account and nothing to unlock: generate, copy and download without signing in. The only limit is ten generations a minute from one connection, which exists to stop scripted abuse rather than to sell an upgrade. Reach it and the panel shows a network error message until the minute rolls over.
Five: Twitter/X, Instagram, LinkedIn, Facebook and TikTok. Your choice is prepended to the topic as a line reading 'Platform:', which steers the tone and shape of the post. A network outside the list can be named in the topic itself, though the selector will still say something else.
No. The platform name only steers the writing; nothing validates the length. A post generated for Twitter/X can come back several hundred characters long, so check the character count printed under the result and trim before posting. Ask for 'maximum 240 characters' in the topic to push it shorter.
Yes, always: the instruction behind the page asks for relevant hashtags, so they arrive as part of the post. There is no field for how many. One LinkedIn run produced fourteen, which is far more than that network rewards, so state a number in the topic if you want restraint.
The text is yours to publish, including on brand accounts. Read it first: the model writes confident specifics that may be invented, and a claim about recycling, certification or performance that you cannot support is a problem on a company account regardless of who drafted it.
Because a language model fills gaps with plausible detail rather than leaving them empty. Asked about recycled daypacks it produced 'every pack saves 1.5 plastic bottles', a figure the brief never mentioned. Give it the real numbers you want used, and delete any that appear without your supplying them.
The language of the page, not of your topic. The page sends its own locale with the request, so the English page answers in English even if the topic is written in German. To get another language, open that language's version of this tool and paste the same topic there.
It varies with the brief and the platform. One LinkedIn run came back at 130 words and 999 characters including hashtags. The counter under the result gives the exact figures, which matters because none of the platform limits are enforced here.
No. It writes text and nothing else: there is no connection to any account, no scheduling, no image generation and no analytics. Copy the result, or download it as ai-social-media-post-result.txt, and paste it into whichever scheduler or app you already use.
The request is routed to whichever hosted model is available at that moment, and its name is printed under the result, so consecutive runs often use different models. The generation is also sampled rather than deterministic, so even one model rewords on a second attempt. That is what Regenerate is for.
