Free AI Instagram Post Generator

An AI Instagram post generator turns a short description of what you want to promote into a post image and a caption. Tell Deepege what the post is for, the exact words for the image and the style, add a product photo if you have one, and get a feed post or a story you can edit in the same chat.

Mockup: a candle product photo attached in chat and the Cedar & Fig Instagram post built around it

Posts built around your real product

Attach a product photo in the chat and Deepege uses it as a reference, so the candle, bottle or dish in the post looks like the one you sell. Use it for new arrivals, restocks and seasonal offers without a new photo shoot each time. AI can redraw small details such as labels, so check them before you post.

Mockup: the same Matcha Week design as a square post, a 4:5 portrait post and a 9:16 story

Feed posts and stories from one idea

Ask for a square post, a 4:5 portrait post that fills more of the screen in the feed, or a 9:16 story from the same brief. Each version is generated for its own shape, so the headline and the product stay in view instead of being cropped off.

The caption comes with it

Ask for a caption in the same chat: a friendly line, a question that invites comments, a call to action and a few hashtags. Change the tone, make it shorter or write it in another language until it sounds like your brand, then copy it with the image.

What to put in an Instagram post brief

A post gets a quick glance in a busy feed, so the image should carry one idea. A useful brief covers:

What the post is for: a new product, an offer, a listing, a class or a tip.
The exact text on the image, in quotes. Keep it to a headline and one short line, and put the details in the caption.
The shape: square for the feed, 4:5 portrait, or 9:16 for stories.
The look: colors, mood and what should be the hero of the image.
The caption you want: tone, length, a question or call to action, and how many hashtags.

How this tool works

Edit the prompt above with your product, text and style. After you sign in, Deepege opens a new chat and sends your prompt. The image appears in the chat, with the caption if you asked for one. You can attach a product photo, ask for edits or other shapes, and download the image. For shop windows and printed promotions, try the AI poster generator. To promote the same offer in a short video, start with the AI video script generator.

FAQ

What is an AI Instagram post generator?

It is a tool that creates an Instagram post image, and a caption if you want one, from a written description. On this page you describe what you are promoting, the text and the style, and Deepege chat generates the post, which you can then edit or resize by chatting.

Is this Instagram post generator free?

Yes, you can try it for free. You get free credits when you sign up, so you can open Deepege chat from this page and create posts right away. When the credits run out, you can keep going on a paid plan.

What sizes can I make?

Say the shape in your prompt: square for the feed, 4:5 portrait, or a 9:16 story. You can ask for other versions of the same post later in the chat.

Can I use my own product photo?

Yes. Attach a product photo in the chat and say how it should appear, for example "keep the jar and label looking the same". AI can redraw small details such as labels or logos, so check them closely and add your final logo in your own design tool if it must be exact.

Will the text on the image be spelled correctly?

AI image models can still misspell words or change numbers. Keep the text on the image short, put the exact wording in quotes, and check prices, dates and spelling before you post. If something is wrong, ask Deepege to fix it in the same chat.

Can I use the posts for my business?

You can use them in your own marketing. Make sure you have the rights to any photos, logos or brand assets you upload, and see the Deepege user agreement for licensing details.
