AI Social Media Post Generator
Image, caption, and hashtags — done in 10 seconds.
Stop staring at a blank Canva. Describe what you're posting about; the AI generates an original image, writes a caption that sounds like you, and picks hashtags that actually match. Ready to share to Instagram, Facebook, LinkedIn, or TikTok.

Image + words in one shot
Most tools give you a template and leave you to write. instaCards generates the image AND writes the caption AND picks the hashtags. One prompt, one finished post.
Sized for every platform
1:1 feed, 4:5 portrait, 9:16 story/reel — pick your format and the post is already the right dimensions. No cropping, no Canva resize.
Captions that don't sound like AI
You give the tone and context; the AI matches it. Posts read like a person wrote them — because you guided it.
Hashtags that actually match
Not the same 30 hashtags everyone uses. The AI picks a balanced mix of broad and niche tags based on what you're actually posting about.
