Instagram Post Generator
What is an Instagram post generator?
An Instagram post generator turns one prompt into a ready-to-post visual plus caption and hashtags. Instacards is built for square feed posts, 4:5 portrait posts, and 9:16 Story or Reel graphics.
Best for small businesses
Use it for product launches, menu specials, service reminders, testimonials, local events, before-and-after posts, and quick behind-the-scenes updates.
Not a scheduler
Instacards creates the assets and copy. You stay in control and publish manually through Instagram or paste the finished post into your preferred scheduler.
Image, caption, hashtags — every part of the post, in 10 seconds.
The hardest part of Instagram isn't pressing publish — it's the blank screen before it. Describe what you're posting about; the AI generates an original image, writes a caption in your voice, and picks hashtags that actually match. Ready for feed, portrait, or story/reel.

One prompt, finished post
Most generators give you a caption OR an image. Instacards gives you both — plus matched hashtags — from one description. Nothing to assemble afterward.
Right size for every format
Pick 1:1 feed post, 4:5 portrait, or 9:16 story/reel. The image is generated at the right dimensions — no Canva resize, no awkward cropping.
Captions that sound like you
Pick the tone, give a one-line context, and the AI matches. Captions read like a person wrote them, because you steered them.
Hashtags that actually fit
A balanced mix of broad and niche tags based on what you're actually posting about — not the same 30 hashtags every guide recommends.
