A month of Instagram posts, designed and captioned by AI.

What an AI Instagram post generator should actually produce

Most tools that call themselves an Instagram post generator produce one of two things: a caption with no image, or an image with no words. Neither is a post. A finished Instagram post is a headline on a branded graphic, a caption underneath it, and the right dimensions so nothing gets cropped in the feed. Creobee produces all three at once, for every post in the batch.

The generator starts from your business, not from a template gallery. You describe your niche, your audience, and your tone in a couple of sentences. A language model turns that into short headlines and longer captions that fit the way you talk. Then the browser draws each headline onto a 1080 by 1350 canvas with your logo where you placed it and a background you chose. The words are real type, so they are always spelled correctly and always readable.

Why every post is 4:5 portrait

Instagram displays every feed post at the same width, so a taller post owns more of the screen. The 4:5 ratio, 1080 by 1350 pixels, is the tallest format Instagram shows in the feed without cropping. A square post at the same width is 25 percent shorter, and a landscape post becomes a thin strip. Creobee renders every image at exactly 1080 by 1350 and keeps text inside a safe margin so it survives the profile grid too.

The same file works on Facebook, LinkedIn, Pinterest and Threads without a redesign, which is why the batch you generate here is a week of content on several platforms, not just one.

Why 4:5 portrait is the best Instagram post format

Captions built on marketing frameworks, not filler

Generic prompts produce generic captions. Creobee asks a few structured questions instead. You can pick a framework such as StoryBrand, the Red Thread, hook-first pattern interrupts, or Purple Cow positioning, and answer three or four short questions about your customer, their problem, and your promise. The AI writes headlines and captions inside that structure, so each post has a point, a hook, and a call to action. If you are in a hurry, the fast track skips the questions and works from your product description alone.

The four frameworks behind the captions

Branding that stays put across the whole batch

Brand consistency is the thing hand-made posts lose first. The logo drifts a few pixels, the font changes, the background gets busier every week. In Creobee, you set the logo once, choose one of six anchor positions, and pick a background: one of ten designed templates, a photo you upload, or an abstract background generated to match your colors. Every post in the batch follows the same rules, so your grid looks like one brand made it.

You also control the text: size, width, alignment, and which single word gets highlighted in your brand color. Those settings are saved with each batch, so your next batch starts from the look you already approved.

Where to put your logo on social posts

What you get, and what it costs

Each finished post costs one credit. The Basic plan is $9.99 a month for 50 posts, and the Pro plan is $19.99 a month for 200. Every plan includes AI captions, your logo, all ten backgrounds, ZIP download of the whole batch, and a gallery that re-renders any past post on demand. There is no free tier and no watermark. There is a 7-day money-back guarantee, so you can generate a real batch and decide with the results in front of you.

Rendered images are never uploaded to our servers. They are drawn in your browser and only your settings and assets are saved, which is why a gallery of hundreds of posts costs nothing extra.
