1 Describe your post, 2. Configure additional options 3. Generate your caption

1. Describe your Caption

Mention what's your post about in the input section above. Something like "Launching a new sneaker drop next week, STARBURST series." Provide as much information as you can, so that our ai-powered generator can create an engaging caption. Another example would be "A post on my recent trip to Bali, where I climbed an active volcano: Mt Agung and saw the most beautiful sunrise."

2. Configure & Generate

You can control the length, include hashtags & emojis too. After you're ready, push the generate button. If you want a longer caption, select "long" in the length section. So, if you want a short caption, select "short". If you want a medium length caption, select "medium". If you want a long caption, select "long". Caption length is a debatable topic, so it totally depends on how you want it to be.

3. Copy the Caption & Post

It'll take a few seconds to generate the caption, after that, just hit the copy button and post it on Instagram. You can generate more variations by hitting the "generate again" button.

Why do I need this?

Writing captions is hard. A post's engagement is quite dependent on how well you're able to grab the reader's attention with your post and the caption supporting it. You need to either supplement or summarize the whole post in a few words, then find relevant hashtags & maybe also include emojis to make it more colorful.

That's why we've built this free AI caption generator. I just a few clicks, you can get attention-grabbing captions based on your brand's voice or brand identity. Just give in a short description & mention your brand's personality in the input section, and our caption generator will generate social media captions for you.

What makes for a great caption?

To create the perfect Instagram caption for your target audience, you first need to know your followers really well. What gets them excited? What would make them share/comment/like the reel so that it can potentially go viral?

I have seen 1000 word captions that provide super valuable content or a great story to remember, and my friends specifically share the post for the caption. But more often than not, a caption supports your main post and is not the highlight.

First focus on your Instagram post, a caption simply adds to your content, and is not the core. Even a perfect caption would fail if your main content is not good.

What all options do your AI Instagram caption generator support?

We support the following additional options to generate captions:

  1. You can decide the length of the message by choosing "short," "medium," or "long"
  2. To get hashtag ideas, you can choose whether to add hashtags or not
  3. You can also control whether to add emojis or not

The advanced options are available on the right side of the caption generator on desktop, and as a collapsible dropdown on mobile just above the heading.

If you have any suggestions, please let us know by replying to this tweet.

As of now, I plan to add support for the following, if you want any to be done sooner, just reply on the thread above:

  1. Image upload, ability to read your images too & provide a better caption
  2. Select tone, so that the caption matches your vibe
  3. Humanization, although there is no proof, but many algorithms have started to penalize AI-generated captions, so an ability to humanize it
