Why Should You Use an AI-generated Caption Writer for Instagram?

Before we jump into the how — let’s address the elephant in the room: AI-generated content

Social media is abuzz with everything AI right now, and while it won’t replace content writers, marketers, and social media managers, it will change content creation as we know it. 

“I don’t think AI-generated content will replace human writing, nor should it,” says content creator Lucas O’Keefe.

"Instead, it’s a powerful timesaver which we can then supplement with our own unique stories and messages,” he adds. 

So, why not use it to your advantage?

Here at Later, we already encourage the use of our AI-powered tools like Hashtag Suggestions and Best Time to Post

Now, with a writing tool like Later’s AI Caption Writer, you can: 

  1. Save Time 

  2. Streamline Your Workflow

  3. Get Inspiration

#1: Save Time

Between creating content, writing captions, and responding to comments and DMs — managing a social media account is a lot of work. 

Plus, if you’re doing it solo, you’ll also need to block out time to strategize and analyze how your content is performing. 

By leveraging an AI-powered caption writer tool, you can save tons of time. 

“It’s useful for fast-track brainstorming and outlining your copy,” says Later’s Content Marketing Specialist, Alyssa Gagliardi.

#2: Streamline Your Workflow 

Speaking of saving time, many social media managers point to the importance of maximizing their efficiency and batching content.

Content batching is a productivity technique where you create a bulk of content (or captions!) during a set period of time. 

While it may sound like more work, you’re able to focus your creative energy on one task instead of multiple at once. 

So, when you’re ready to write captions for the upcoming week, using a tool like Later’s AI Caption Writer can help make the process easier — especially as it’ll learn to match your brand’s tone based on the language used in previous posts. 

TIP: To maximize your efficiency even further, schedule your Instagram posts when you’re done. Work smarter, not harder. 💪

#3: Get Inspiration 

Consistently writing engaging captions isn’t always a piece of cake — especially when you’re experiencing writer’s block. 

With an AI-powered caption writer, you can get a much-needed dose of inspiration to generate new ideas, hooks, or call-to-actions (CTAs). 

“AI writing tools can provide helpful prompts as a baseline when you’re feeling stuck," says Later’s Social Media Manager, Christine Colling.

“However, it’s still important to edit and tweak the copy to make sure it’s on-brand and telling the story you want to tell,” she adds. 

Goodbye writer’s block — hello Instagram captions. 👋

How To Use Later’s AI Caption Writer for Instagram (& Schedule Posts)

Later is a social media management platform trusted by over 4M brands, creators, and social media managers to schedule content, analyze data, and more. 

Here’s how you can use our AI-powered Instagram caption generator (and post your content) in six easy steps:

Step #1: Connect Your Instagram Profile

Upgrade or sign up to a new Later paid plan and connect your Instagram profile.

TIP: To add, remove, or transfer your Instagram profile in Later, check out this helpful page

Step #2: Upload Your Content to Later’s Media Library

From there, click “Upload Media” and upload content from your computer, Dropbox, or Google Drive. 

You can also drag and drop files directly into the Media Library, for an even faster process! 

Step #3: Select Content to Schedule 

Choose the Instagram profile you’d like to publish to (double-check the highlighted circle).

Then, drag and drop an image or video from your Media Library to the content calendar: 


Step #4: Select the AI Caption Writer Tool

To generate your caption, click on “AI Caption Writer” in the Post Caption field:

Step #5: Type in Your Text

Input text (between 3-80 characters) that describes your post. 

It could be a description of the image or video you’re using, or the general topic of the post — for example, celebrating the launch of a new product.

Try to use specific keywords, and remember to include your brand’s tone of voice.

Click “Generate Captions” and you'll have new captions in seconds: 

Up to three captions will be generated — with various lengths, copy styles, and occasionally emojis or hashtags. 

Click on the caption you’d like to use, and it will automatically get added to your Post Caption field: 

From there, you can edit the caption, insert more relevant emojis or hashtags, add a first comment, add design elements to your content (like filters), and tag other accounts.

NOTE: You can also apply a thumbs up or thumbs down to the generated captions — this will allow Later’s AI Caption Writer to adapt to your style. 

Step #6: Choose the Date and Time to Schedule Your Post

If you have an Instagram Business profile, select “Auto Publish” from the dropdown list and select the date and time you want your post to go live. 

Click “Save” — and voila! 

NOTE: If you have an Instagram Creator or Personal profile, you cannot auto-publish posts due to Instagram’s API limitations. Instead, you'll receive a mobile notification when it's time to post. 

So, do we think you should switch to only using Instagram caption generators? No.

But they can be a great feature to help you save time and get those creative juices flowing.

Plus, judging by the sudden boom in AI-powered tools for social media, this is just the beginning.

Stay tuned. 👀
