AI Product Post Generator: Turn Any Product Page into Posts for All 9 Platforms

PostAnything is an AI product post generator that starts from the page you've already written. Paste a product link and it reads the product's name, price and details, pulls in your product photos, and writes product social media posts for Facebook, Instagram, LinkedIn, Pinterest, X (formerly Twitter), Threads, Bluesky, TikTok and YouTube. You check them over, pick a time, and PostAnything publishes them for you.

It's built for the way small stores actually do ecommerce social media marketing: one person, a growing catalogue, and no time to write the same announcement nine times.

How our AI product post generator turns a product page into posts

Most tools that promise to promote your products either design a graphic or push the same caption everywhere. PostAnything writes a separate post for each platform, using the details already on your page.

It reads your product page for you

Choose the URL tile and paste your product link. PostAnything reads the page and summarises it, including the product name and description, and usually the price, so your captions use real details instead of vague hype. It works with Shopify and WooCommerce product pages and almost any other online store.

The exception is Etsy, which blocks automated reading. For an Etsy listing, upload your product photo in the Photo/Video tile, or type the key details into the Text tile.

Your real product photos, never AI-made ones

After you click Generate, the images found on your product page appear in a carousel in the Post Image card, and whichever one is showing is the one that gets posted. PostAnything doesn't generate AI images, so shoppers see your product exactly as it looks in your store.

You don't need to crop anything, either. Each photo is automatically resized for every platform when it publishes, so it fits each feed without you opening an editor.

Which platforms a product photo covers

A product photo is enough for seven platforms: Facebook, Instagram, LinkedIn, Pinterest, X, Threads and Bluesky. TikTok and YouTube need a video. If you have a product clip, swap the photo for it in the Post Image card after generating, using Upload my own photo or video. A post carries one photo or one video, so the clip replaces the photo. PostAnything then writes the TikTok and YouTube captions automatically, and Instagram and Pinterest still get the post. Here's more on posting one video to TikTok, Reels and Shorts.

Before and after: one product page, nine ready-to-post captions

Here's what that looks like with an example product page. The store and product are made up, but the steps are exactly what you'll see in the app.

The input: a product page at yourstore.com/products/waxed-canvas-tote for a Waxed Canvas Tote. It costs $68, is water-resistant, has solid brass hardware and fits a 15-inch laptop. We pasted the link into the URL tile and clicked Generate, then left the main product shot showing in the carousel.

The output: a caption card for each platform in Step 2, each written for that platform. The product photo covered seven platforms. To bring in TikTok and YouTube, we then swapped it for a short clip of the tote in the rain, using Upload my own photo or video in the Post Image card. Here's what all nine platforms got. PostAnything added the product link to the end of every caption, and made it the Pinterest pin's link too.

How to create product social media posts from a product URL

Once your accounts are connected, a product post needs just three steps from you, and PostAnything writes every caption in seconds.

Here's the full process, from sign-up to a scheduled post. For the bigger picture, see how PostAnything works.

Review and schedule

11. Optional Check the product link at the end of each caption. On Instagram and TikTok it shows as plain text, since links there can't be clicked, so point people to your bio too. Pinterest also uses it as the pin's link.
12. Optional Edit any caption directly. Click a card's refresh icon to rewrite just that platform, or use its switch to leave that platform out of this post.
13. Optional Click Preview to see how the post will look.
14. Choose Schedule for Later and pick a date and time, or choose Post Now.
15. Click Schedule Post.

Your post then appears in Post History, marked "Processing" until each platform confirms it. If you haven't connected any accounts yet, you can still generate and preview every caption. You just can't schedule until you connect.

Product launch social media posts from a single page

A launch usually needs more than one post. Here's a simple way to build a sequence around one product page, using features included in every plan:

• Before the page is live: use the Text tile to write a teaser, such as "Something rain-ready lands Friday", and schedule it with Schedule for Later.
• On launch day: paste the new product page into the URL tile and choose Post Now.
• A few days later: generate from the same page again with a different Tone, say Playful instead of Professional, for a fresh new product social media post.

On Pro, My History also lets you remix your launch post later and reuse its media, and Audio Note lets you turn a voice memo into a social media post when talking is quicker than typing. Every post in the sequence counts as 1 against your plan, however many platforms it goes to. They all sit on the Calendar, where you can open any post and Cancel Post if plans change.

A rhythm that suits most small stores: the teaser two or three days before launch, the launch post on the day, and a follow-up about four days later that leads with a different detail, such as the brass hardware instead of the rain-proofing. Put that angle in Custom Instructions ("Lead with the brass hardware") so the follow-up doesn't repeat the launch post. If the product sells well, a fourth post a couple of weeks on, like a "back in stock" note, keeps it in people's feeds.

That's four posts, each going out to every platform you've connected and counting as 1. On Basic, that leaves 26 of your 30 for the rest of the month.

A product caption generator that writes in your brand voice

A product caption generator is only useful if the captions sound like your shop. When every post reads like a generic AI listing, followers scroll straight past.

PostAnything handles brand voice for social media in two places. Voice & Style learns your tone, sentence style, emoji use and hashtag habits from your past posts or writing samples, then applies them to every caption. Custom Instructions set rules for how each post is written, like "Always mention free shipping" or "End with a question".

Each platform still gets its own treatment. Product Instagram captions get emojis and hashtags if you've switched them on, a product Facebook post gets fuller detail, and X gets the short version. If you'd rather choose the mood yourself, set Tone to anything from Casual to Persuasive, or leave it on Auto. You can see the rest of PostAnything's features on our homepage.

Social media for ecommerce, whatever your store runs on

Good social media for ecommerce comes down to a few basics on every post: a clear photo of the product, a reason to want it, the price, and a link straight to the page. PostAnything takes all four from your product page, and adds the link to every caption.

Shopify products to Instagram (and the other eight platforms)

Shopify already lets you share a product page from your admin or copy its link. That's handy for posting one link to one network. PostAnything takes the same product URL and writes a post for each platform you've connected, with no Shopify app to install. WooCommerce stores work exactly the same way.

If you sell through an Instagram shop, you can still add shopping tags. Instagram lets you tag products in existing posts, so publish with PostAnything first and add the tags in Instagram afterwards.

Got a store blog too? You can turn blog posts into social media posts the same way. Have product demos on YouTube? Paste the link and turn each YouTube video into social media posts for every platform.

Promoting a whole catalogue with Bulk Schedule

On Pro, Bulk Schedule lets you line up a month of product posts in one sitting. Choose Generate from Media, upload your product photos (or a whole folder), and AI writes a caption for each one. Pick your Platforms for this batch, review every row, then use Auto-fill blank times to spread the posts across the days you choose.

These captions come from your photos rather than your product pages, so add prices and links as you review each row.

Which plan fits a store posting products?

Most small stores are well served by Basic at $15 a month. It includes the URL tile and 30 posts a month, each one going out to every platform you've connected. That's enough for a product a day.

Choose Pro at $29 a month if you have a bigger catalogue or post more than once a day. You get 300 posts a month (still counted once per post, whichever platforms it reaches), plus Bulk Schedule, My History and a media library for reusing your product shots. Both plans cost less when billed annually. See all PostAnything plans and pricing.
