Instagram Caption Generator

No. The tool uses curated caption patterns adapted to your topic and niche via simple substitution. It runs entirely in your browser, never calls an AI API, and returns results instantly. If you want real AI generation that writes a full narrated video as well, our paid product at /prompt-to-video does that end to end.

2,200 characters as of 2026. Captions get truncated at roughly 125 characters in the feed (the "more" cutoff), so your hook needs to land in that first line. Hashtags count toward the 2,200-character total.

Instagram allows 30 hashtags per post, but most data points to 10-20 niche-relevant tags out-performing 30 generic ones. The generator lets you choose 10, 20, or 30, and pulls from a niche-specific bank rather than a generic top-100 list.

It depends on the format. Photo/Reel feed posts perform best at 70-150 words. Carousel posts can go longer (200-400 words) because the user is already swiping. Story captions should stay under 140 characters because the text-on-image styling falls apart past that.

Yes. Generated captions are free for any use — your own posts, client posts, paid campaigns, agency work — with no attribution required.

Most competitor tools give you one or three captions and force you to regenerate to compare. We return 12 spread across seven archetypes (hook-first, storytime, listicle, question-led, aesthetic, promo, value-bomb) in a single batch so you can see which format suits this post at a glance.

No. Instagram does not detect or penalise generated captions; it ranks posts on engagement signals (saves, shares, comments, watch time on Reels). The risk is using generic captions that do not match your voice — edit any generated caption before posting so it sounds like you.
