Our AI social media post generator writes one or more posts for Facebook, Twitter, Instagram, LinkedIn or Reddit from a short description. You choose the tone, creativity level, language, approximate word length and post count. It suits small businesses, marketers and creators who need drafts fast. Review each post before publishing. Free, no sign-up.

Write for Facebook, Twitter, Instagram, LinkedIn or Reddit, so the draft starts closer to each network's style.
Choose from Formal and Friendly to Persuasive, Educational or Satirical to match your brand voice.
Pick Be Creative, Be Specific or Both Specific and Creative to set how freely the AI writes.
Set an approximate word length and a post count to get several drafts in one run, in four languages.
Three steps from a blank form to a result you can use.
Choose a Platform and write the topic, offer or news in Post About. Include facts the post must mention.
Pick a Tone of the Post, Creativity Level and Language, then set Approximate Word Length and Post Count.
Click Generate, compare the drafts, copy the best one and check facts, links and hashtags before you publish.
Every network rewards a different kind of post. A LinkedIn update, a tweet and a Reddit post about the same news need different lengths and tones, and this tool lets you set those choices before the AI starts writing.
The Platform field shapes the draft, but limits and norms still differ. Character limits below come from Buffer's help center.
| Platform | Character limit | What we suggest |
|---|---|---|
| Very long posts allowed. SocialPilot lists up to 63,206 characters | Lead with the hook. Keep the main point in the first line or two | |
| Twitter (X) | 280 for free accounts, 25,000 for paid tiers | One idea per post. Set a low word length |
| 2,200 for captions | Write for the image. Put the key line first | |
| 3,000 for posts | Professional or Educational tone, with a clear takeaway | |
| Rules vary by community | Read the community's rules first. Lead with value, not promotion |
We suggest generating per platform rather than pasting one post everywhere. Run the tool once for LinkedIn, then change Platform to Twitter and lower Approximate Word Length for a shorter take on the same news.
Creativity Level controls how freely the AI writes. Be Specific keeps the wording close to what you put in Post About, which suits announcements with dates and prices. Be Creative allows looser, more surprising wording, which suits awareness posts and brainstorming. Both Specific and Creative sits in between.
The 19 tones fall into rough groups:
We suggest testing edgy tones on a personal account before using them for a brand. Sarcasm and irony are easy to misread in a feed, and Controversial posts can draw replies you will need to manage.
The Post About field is where most of the quality comes from. SocialBu's guidance for its own generator lists the details that improve results: the audience, key facts, the action you want, and any words or claims to include or avoid. The same applies here.
| Include | Weak brief | Stronger brief |
|---|---|---|
| Audience | Our new course | Our new course for first-time team leads |
| Key facts | Starts soon | Starts in two weeks, six weekly sessions, online |
| Action | Check it out | Reserve a seat through the link in our bio |
| Limits | None given | Do not mention price, avoid the word guru |
We suggest writing the brief as if you were handing it to a new colleague. If they could write the post from it without asking questions, the AI can too.
Example: a small agency is running a free webinar on client onboarding. This is an illustration of how we would fill in the form.
Post About, used for both runs: Free 45 minute webinar on client onboarding for agencies, Thursday at 2pm ET, link in comments, covers kickoff calls and first-week checklists.
| Field | Run 1 | Run 2 |
|---|---|---|
| Platform | ||
| Tone of the Post | Professional | Friendly |
| Creativity Level | Be Specific | Both Specific and Creative |
| Language | English | English |
| Approximate Word Length | 120 | 35 |
| Post Count | 3 | 3 |
The agency picks one LinkedIn draft and one tweet, checks that the date, time and topic match the facts, and counts the tweet's characters against the 280 limit. They add the real link themselves, since the AI cannot know it.
If you plan a week of posts like this, listing each one as a task with a publish date in a project tool such as Onethread keeps drafts, approvals and dates in one place.
Quick answers about the Social Media Post Generator.
You can choose Facebook, Twitter, Instagram, LinkedIn or Reddit in the Platform field. The choice shapes the style of the draft. You still need to check each network's limits and norms, such as the 280 character limit for free accounts on X or a subreddit's own posting rules.
It sets how freely the AI writes. Be Specific keeps the wording close to your Post About details, which suits announcements. Be Creative allows looser, more varied wording for awareness posts. Both Specific and Creative mixes the two. Try different settings on the same topic and compare.
Yes. Enter a number in Post Count to get that many drafts in one run. Comparing three or more drafts helps you find the strongest hook, and you can combine lines from different drafts. Each draft follows the same platform, tone, language and length settings.
The Language field offers English, Spanish, French and German. Write Post About in any of them, then choose the output language. Ask a fluent speaker to review posts in a language you do not speak well, because AI translations can sound stiff or miss local phrasing.
We suggest you never do. The posts are generated with AI and may include wrong details, a tone that does not match your brand or claims you cannot back up. Read each draft, check facts and length, add your own link and hashtags, and then publish.
Yes. It is free to use and needs no sign-up. Fill in the form, click Generate and copy the drafts you like. You can run it as often as you need for different platforms, tones and topics.
