AI Instagram post maker for the feed
Our AI Instagram post maker writes the image brief, caption, hashtag set, and CTA as one coordinated post, not four pieces stitched together.

Why an Instagram single post is four pieces, not one.
A working Instagram single post is four coordinated pieces: an image at 1080x1080 or 1080x1350, a caption with the hook in the first 125 characters before the see-more cut, 3 to 5 niche hashtags in the first comment, and a CTA tuned to whether the post should earn saves, shares, or follows. Most post makers handle one of these and leave the others to drift out of alignment. Our AI generates all four as one artifact, so the caption hook matches the image angle, the hashtags match the niche signal, and the CTA matches the post type.

Four coordinated pieces, generated together as one post.
Most post tools generate the caption and let you handle the image, hashtags, and CTA separately. Ours generates all four as one coordinated artifact. The hook in the caption matches the angle in the image brief. The hashtags match the niche signal in the caption. The CTA matches the post type. The pieces reinforce each other instead of drifting.
Common use cases for the AI Instagram post maker

Instagram single post questions from active creators
What creators ask once they've shipped a few posts.
Square or portrait for the image format?
Portrait (1080x1350) takes more screen space in the feed and outperforms square by 10-20 percent on impressions in most niches. Square works for grid consistency. Pick one and stick with it across your feed for the visual rhythm.
How long can the caption run past the hook?
Up to 2,200 characters total. Most engagement comes from posts under 500. Our AI keeps the post tight by default and only expands when the topic genuinely needs the room.
First comment vs caption for hashtags: does Instagram actually weight them differently?
Same discovery signal either way. The first-comment placement just keeps the caption clean for readers. Our AI defaults to first comment for aesthetics, but the algorithm reads them either way.
How many hashtags per post is right?
3 to 5 niche-relevant tags. Past 5 the signal dilutes. Generic hashtags like #love don't help; specific niche tags do.
Will our AI auto-post to Instagram?
Yes for Instagram Business or Creator accounts. Connect the account once and our AI posts on schedule. Personal accounts still need manual posting per Meta's API.
Can our AI generate the image too?
Our AI generates the image brief: angle, focal point, composition. The actual image creation happens in Sintra's image tool, Canva, or your designer's pipeline. The brief gives them everything they need to deliver the visual.
