Caption, video, posted
The caption is ready. Post the Reel with it.
MakeAIVideo makes the Reel from a prompt or a script, then posts it to Instagram for you. The post dialog drafts a caption with hashtags from your script, or you paste the one you picked here. See the Instagram Reels generator and auto post.
- Posts as a Reel.
- Vertical videos go to Instagram as Reels.
- Counted before it goes.
- The caption is checked against Instagram's 2,200 characters, and against the shortest limit when you post to several platforms.
- Now or scheduled.
- Leave the time empty to post now, or pick a date and time.
We upload the finished file to each account you pick.

Instagram Caption Generator FAQs
Something else? Visit the help center
Are these captions AI-generated?
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, the paid prompt to video mode does that end to end.
What is the Instagram caption character limit?
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.
How many hashtags should I use on Instagram?
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.
What is the ideal Instagram caption length?
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.
Can I use these captions commercially or in client work?
Yes. Generated captions are free for any use, your own posts, client posts, paid campaigns, agency work, with no attribution required.
Why are there 12 captions per generation and not just one?
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.
Will Instagram penalise me for using a caption generator?
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.
Want to actually make the video?
MakeAIVideo turns one prompt into a finished AI video: script, voiceover, scenes and captions, with music if you want it, ready in a few minutes.
