What is an Instagram Caption Generator?

An Instagram caption generator is a content creation tool that not only generates catchy captions but also aligns perfectly with your brand identity and brand voice (when given the proper prompts, of course). 

Utilizing these AI tools is like unlocking a treasure trove of creative energy. They understand your content’s context and tone of voice. Also, they even suggest relevant hashtags to amplify your reach. Moreover, they’re equipped to handle different languages, making your content accessible to a global audience. This user-friendly interface aids in overcoming the dreaded writer’s block. 

These tools provide a plethora of caption ideas with just a click of a button.

No kidding. I’ve tried them before. I use Koala, and it’s awesome.

Koala

I was trying to come up with 7 days’ worth of social media posts for Instagram, Facebook and LinkedIn, along with relevant hashtags for an upcoming masterclass a client was going to launch.

I turned to Koala.

I tweaked the results a little, but 90% of it was good to go.

Imagine the amount of time I saved, and yet came up with quality posts!

Koala gave me not only the captions, but the hashtags as well!

I went one step further and asked that it gave me video ideas for the content should I be doing reels and stories.

Bam. It delivered.

It therefore goes without saying that Koala is my fave, fave, fave go-to caption generator as well as content creation tool.

The ONLY thing I have to remind you about it to ALWAYS fact check articles and content you get from AI.

Don’t just copy and paste. That makes you the less-than-ideal freelancer or service provider.

Read, reread. See how you can tweak it better to suit your clients’ needs, and add that human touch to it. Make it more personalized.

OK, lecture over.

I listed another 5 free AI caption generators for Instagram – Koala ranks top on my list, of course.

Bear in mind, though – that Koala is not just another AI caption generator – it can create blog posts, articles, newsletters, and lots more.

It comes with a free trial that allows up to 5,000 words!

Rating for Koala: 5/5

Grammarly

Grammarly excels as an AI caption generator, ideal for crafting error-free and engaging Instagram posts. Grammarly stands out as a valuable tool for anyone looking to make appealing captions. Also, it helps to level up the Instagram marketing. It combines the power of AI with user-friendly features, making it a go-to choice for generating catchy Instagram captions.

All I did were 3 steps:

  1. Give an idea of what the situation or atmosphere is about – here I keyed in “3 pretty girls sitting together, catching up in a beautiful cafe”.

  1. You’re required to key in your tone of voice. I did “fun, playful, and thoughtful”.

  1. Grammarly comes up with the captions – 5 variations. All you need to do is copy them and use the ones that you like. There is  even a copy button you can use!

As you can see, this kind of caption generation is more suited for photos and images.

If you want something totally different (as with the webinar example above), then Grammarly may not work for you.

On the other hand, this graphic scenario can easily work in Koala.

Pros of Grammarly

  • Advanced Grammar Checks: Ensures captions are grammatically correct.
  • Versatile Tone Settings: Adapts to different styles, matching your brand voice.
  • Multilingual Support: Great for reaching a global audience.
  • Integration with Platforms: Works well with various online tools.

Cons of Grammarly

  • Creative Limitations: Sometimes less flexible in creative expression.
  • Input-Dependent: The quality of suggestions relies on your input details.

Grammarly is a popular choice for those who prioritize quality and consistency in their social media content, making it a valuable tool for enhancing social media marketing.

Do I recommend it? Yes.

Copy.ai

Copy.ai is an innovative AI Instagram caption generator that offers a creative edge to your social media posts. Copy.ai is also an excellent choice for enhancing your Instagram marketing strategy. It combines the power of AI with user-centric design, making caption generation both efficient and creative.

This one requires you to input an image – hence also limiting its features to only posts with graphics, and not stories, reels, or normal LinkedIn or Facebook posts.

Even more, you can’t upload the image – you need to upload it to maybe a Google Drive first, grab the link and drop it in the box!

It was an immediate put-off for me – but it’s in this list because it’s a free tool.

I tried it anyway. Haha.

I uploaded the image to Google Drive, dropped the link (made it publicly viewable), and put in descriptions as shown below:

After literally 5 minutes of waiting, it was still generating…so I gave it up.

Pros of Copy.ai

  • Easy-to-Use Interface: The tool is user-friendly, making it accessible for both beginners and experienced users. This ease of use is particularly beneficial for those new to AI tools.
  • Range of Styles: Copy.ai provides a multitude of styles and tones, enabling you to find the perfect match for your brand identity and the specific needs of your Instagram posts.

Copy.ai as a content creation tool (for emails, blog posts) is actually quite decent. I gave it a trial run before. I canceled my subscription after that because I felt it wasn’t intuitive enough and required a learning curve. 

Cons of Copi.ai

  • AI Quality Variation: Sometimes, the quality of the generated captions can vary, which might require additional tweaking to get the right caption.
  • Takes too long to generate: At this point it has been 10 minutes, and I have not gotten my captions. There are no clear instructions as to what image URLs we should use, so I have just given it up.

Do I recommend it as a caption generator? No.

Instasize

Instasize free caption generator

Instasize made me happy right off the bat.

No image upload needed, yay!

This works super well for me because as a freelancer, I don’t typically just sit there drinking coffee and try to come up with meaningful or thoughtful captions that do not help my followers in any way.

My clients require I come up with social content that drives traffic to a challenge, a summit, an event, or create captions that provokes one into wondering and thinking.

I gave Instasize a try to see how many captions it’ll generate and the results it can produce. There are several tones you can choose from, and I chose Inspirational. 

Now for the results!

Different types of tones available on Instasize

So Instasize gives just ONE caption each time. To generate new ones, you’ll have to press the ‘try again’ button.

It’s a long-ish caption and it does come across as inspiring.

But! Big boo boo. It does not give you hashtags! Gasp! #weneedhashtags

Pros of Instasize

  • User-Friendly Design: Instasize is known for its intuitive interface, making caption and image editing easy and enjoyable.
  • Diverse Caption Options: Gives you the ability to choose up to 8 different tones.

Cons of Instasize

  • Only one caption at a time – you’ll need to copy and paste a multitude of times onto a Google Doc after generating new ones and finally settling for one.

Do I recommend it? Somewhat yes.

It gives 2 different caption results and made them cute. However, I opted for 5 hashtags and it did not seem to be able to generate 5.

The first caption had 4, and second had only 2.
