Caption
Long + short
The long version fits the subject. The second version stays under 280 characters for shorter channels.
Free social post generator
Turn your website into a social post.

Free limit
One post
See the first finished format before email. Email only unlocks the other two formats and saves the work.
Your website is the starting point
You bring the website. Boomp prepares the content.
01
Read your business
Boomp reads public services, FAQs, process, and proof to learn what you do and who you help.
02
Make the complete item
Boomp reads your public pages, chooses one supportable topic, writes a long caption and a short version, and makes a branded image. A post often takes about two minutes. The result page shows progress if it needs longer.
03
Review the result
Check the words, media, facts, permissions, and next step. You decide what represents the business.
Use the source you already have
What makes a website-based AI post generator useful?
A blank prompt knows almost nothing about a business. A website can supply services, process, explanations, proof, and the words the business already uses. Boomp starts there so the first draft has facts to work from instead of relying on a business name and industry label.
The tool does not copy a page into a caption. It looks for one useful idea that can become a complete post. A service detail can become a practical tip. An FAQ can become a direct answer. A process page can become a short explanation of what a customer should expect.
Website grounding reduces generic filler, but it does not remove judgment. Public pages can be old or incomplete. Review the finished caption and image. Correct changing facts, remove claims that need proof, and make sure the post represents the business before you use it.
One item, useful choices
Which platforms can the post work on?
Use the full caption when the extra context helps. The 4:5 image fits the feed without forcing a square crop.
Use the full version for a useful explanation, or the short version when one clear business point is enough.
Use the image and full caption together. Check the final crop and any link direction before publishing.
Paid Boomp accounts can publish approved work to Google Business Profile, Instagram, Facebook, LinkedIn, TikTok, YouTube, Pinterest, Threads, and X. A format still has to fit the destination. Always review the final crop, caption, and platform composer.
Limits that matter
What the free generator does not do
- Boomp needs a public business website with enough useful detail to read.
- The free allowance is one finished post, one carousel, and one faceless video per business.
- The current generator reads and writes English. It does not translate the result.
- Your website is a starting point, not complete knowledge of your business. Check every changing fact and claim before you use the result.
- The free tool makes the item. It does not publish it or connect to your social accounts.
One business. Three ways to show up.
Want a free carousel or video too?
After your first result, email saves the business setup and unlocks one free sample of each remaining format. No free item starts a subscription.

Questions about this free generator
Can AI write my social media posts?
Yes. AI can turn clear business source material into a useful first draft or finished post. The result is stronger when it starts from real services, FAQs, process, and proof. A person still needs to check facts, permissions, tone, and whether the post represents the business.
Is there an AI social media post generator that works from a website?
Yes. Boomp starts with a public business website. It finds one useful topic, writes a full caption and a short version, and makes a 1080 × 1350 image. The finished post appears before Boomp asks for an email, account, or payment card.
Is there a free AI social media post generator?
Yes. Boomp makes one complete post free for a business. The result includes a caption and image and appears before email. The same business can also unlock one free carousel and one free faceless video after sharing an email to save the work.
Can I use an AI post generator with no sign up?
Yes. You can enter a public website and see the first finished Boomp post without an account, email, password, or card. If you want the saved link or the other two free formats, Boomp then asks for an email. The first result stays ungated.
What is the best AI social media post generator for a business?
The best fit depends on the blocked job. Use a prompt assistant when you want to direct every draft. Use a scheduler when the posts already exist. Use a website-based generator when you want the tool to find a supportable topic and return a complete post for review.
Will posts generated from my website sound like my business?
A website gives the generator real vocabulary, services, explanations, and proof, so it is a better start than a name-and-industry prompt. It is not a complete copy of the owner. Voice becomes more faithful through review, corrections, and clear approval of what the business will say.
