AI Instagram Post Maker
Feed posts, stories and carousels — generated at the right size from one prompt.
Posting consistently is a design problem before it is a content problem. Describe the post — the product, the offer, the mood — and this AI Instagram post generator returns a finished square, portrait or story frame with the type already set, sized correctly for the placement. Add slides to the same project for a carousel, and export every frame without a watermark.

Generated from a one-line prompt — no template picked.

Story frame
Why use this instead of a template
Right ratio, first time
Square, 4:5 portrait or 9:16 story — the layout is composed for the frame instead of a square being cropped and hoping the type survives.
Carousels that hold together
Ask for slide two, three and four in the same style and the palette, type scale and margins carry across the set.
Type that is actually set
Headlines, kickers and price lines land on a real hierarchy — not one font size stretched to fill the canvas.
A week of posts in an afternoon
Batch a month of content by re-prompting the same template with new copy, then export the lot.
How the instagram post maker works
Four steps, and only the first one costs credits.
- 1
Pick the placement
Feed post, portrait or story. This sets the canvas the AI composes into.
- 2
Describe the post
Name the subject, the palette and any words you want on screen — quotes around the copy keep it verbatim.
- 3
Refine in chat
Move the headline, cool the palette, swap the background. Refinements never cost credits.

Export and schedule
Download at full resolution and drop it into your scheduler.

Instagram post sizes worth knowing
Instagram displays feed content at 1080 pixels wide, and every placement wants a different frame beneath that. These are the four to design to:
- Portrait post — 1080 × 1350 (4:5)
- The most vertical space a feed post can take, which is why most brands default to it for anything they want noticed.
- Square post — 1080 × 1080 (1:1)
- The safe all-rounder. Survives being shown as a grid thumbnail without losing anything from the edges.
- Story or Reel cover — 1080 × 1920 (9:16)
- Full screen. Keep type out of the top and bottom sixths, where the profile row and the reply bar sit.
- Profile grid thumbnail — 1:1 crop
- A 4:5 post is centre-cropped to a square on your profile, so anything that must survive the grid belongs in the middle.
The practical trap is designing once and cropping later. A headline centred in a square lands under the profile overlay in a story, and a story composition loses its bottom third in the feed. Generating per placement avoids the recrop entirely.
Keeping a feed visually consistent
Consistency on Instagram comes from three repeated decisions: a palette of two or three colours, one typeface pairing, and a fixed margin. Say those once in a prompt and reuse the same wording, and the grid starts to look designed rather than assembled.
When you want variety without losing the thread, change the photography and hold the type system. Asking for "same layout and palette, new product shot" produces a set that reads as a campaign.
From prompt to carousel
Carousels do the heavy lifting for educational content, and they are where manual design gets tedious — the same frame ten times with different copy. Generate the first slide, then ask for the next with the new text and the instruction to keep everything else identical.
Each slide stays editable by chat, so a change of mind on slide one can be pushed through the rest without rebuilding anything.
Instagram Post Maker FAQ
Pick the placement — feed, portrait or story — then describe the post in a sentence, including any words you want on the image in quotes. Generate, adjust the palette or headline in chat, and export at the right size for that placement.
Square posts at 1080 × 1080, portrait posts at 1080 × 1350 and stories at 1080 × 1920. Pick the placement before generating and the layout is composed for that frame.
No — this is a design tool rather than a copywriting one. Words you put in quotes are set into the artwork exactly as typed, so what you see on the image is what you wrote. The caption under the post is still yours to write.
No. Nothing is stamped on your exports, including on the free plan, so a post can go straight to the feed.
No. It runs in the browser on desktop and phone, so you can generate a post, refine it and download the file without installing anything.
Yes. Refine by chat — a bigger headline, a warmer palette, a different crop — and the same design updates rather than being regenerated from scratch. Refinements do not cost credits.
Yes. Generate the first slide, then ask for each following slide with new copy and the instruction to keep the style — the palette, type scale and margins carry across.
Attach it as a reference image and the AI designs the post around it rather than inventing a stand-in product.
Yes, with credits included and no card required. Generations cost 2 credits each; refinements and exports are free.
Yes — designs you generate are yours to use for your business, including paid promotion.
