Should You Use AI To Write LinkedIn Posts?

Almost half of all LinkedIn long posts are generated by AI, a new study from Pangram finds.

While experts suggest AI can be used for researching and giving structure to ideas, it’s unable to create the authentic, personality-driven content that consumers want to see on their feeds.

Social media influencer JD Alewine spoke exclusively to Tech.co about the downsides of using AI to write content. Authenticity, he says, is something he strives for, and encourages brands to focus on their natural, human ability to tell stories in order to engage their audience.

Nearly Half of All LinkedIn Posts are Generated by AI, Study Finds

In a recent study, Pangram Labs found over 40% of long posts on LinkedIn were entirely AI-generated, contributing to the amount of AI slop now found on social media platforms.

LinkedIn was the “most AI-saturated platform,” of all the social media platforms analyzed, Pangram, the AI-detection platform, noted. Posts from LinkedIn made up 62% of content flagged as AI-generated, despite only accounting for a third of all content analyzed.

Of the LinkedIn long posts identified, 23.9% were entirely AI-generated, and 22.9% were written with the help of AI.

LinkedIn’s use of built-in AI writing tools (the “Write with AI” tool has since rebranded to “Enhance post”, but remains an AI writing tool) could have contributed to the increase in AI content on the platform.

Experts Say AI Can’t Provide an Authentic Experience

We’ve all heard the familiar tics of AI-generated writing. The “it’s not X, it’s Y” comparison, the continuous flow of em dashes, and the monotone thump of three sentence combinations: “Not this. Not that. But this.” Today’s brands need authenticity and personality on social media to earn engagement, and this structure doesn’t exactly support that.

I spoke to JD Alewine, co-owner of social media brand, Them Bites. Them Bites currently has over 200K followers across platforms including TikTok and Instagram. 

Alewine is firmly against the idea of using AI to post on LinkedIn. “We want to try to be as authentic as possible with the content we put out,” he said. “We know that at the moment AI is the current trend, but eventually people will grow tired of how it sounds, and reads. We are over the misuse of it as is.”

Them Bites’ content draws on the authentic and human experiences audiences crave, and these experiences are often missed when content is created by AI.

Alewine isn’t against using AI at all, though, describing it as “more of a tool to use as a jumping off point.” At Them Bites, they occasionally use AI to brainstorm, or to summarize a post they’ve already created. “We think of it as a tool to help the work that you’ve already put in.”

How AI is Changing Social Platforms

I asked Alewine about platforms other than LinkedIn where AI content is rife, and he gave Facebook as another example. However, LinkedIn was the main platform Alewine pointed to. “I have a hunch that it’s because people have gotten so used to flowery language,” on the platform, and as a result, “AI content was easily adapted to that type of user.”

LinkedIn by design is a “corporate communication platform,” says Grace Gosnear, Social Media Manager at LevLane. This makes it different than platforms like Instagram, Facebook and TikTok. People use it to connect in a business sense. Even before AI, content was grounded in polished, efficient corporate-speak. With AI, there’s a risk this is all content will become.

Similarly, there are longer term consequences for social media platforms becoming mostly AI-generated. Jenna Wuu, previously a Global Policy Programs Head at Meta, pointed out that this could impact how AI systems are trained in the future.

“If we enter a world where AI-generated posts become training data for future AI models, we’ll end up with a loop of AI models training themselves on themselves. That’s a risk for AI companies as well as users because it will reduce the overall quality of those systems.” Wuu points towards a future where models become entirely self-serving in the content they produce.

How Businesses Should Communicate with their Audiences in 2026

At the moment, AI can’t match the creativity and innovation humans have. Grace Gosnear used DoorDash’s recent collaboration with T-Pain for the World Cup as an example. “Could AI suggest working with a celebrity? Sure. But could it have landed on that exact execution with that timing and cultural awareness? I don’t think so.

“That’s the kind of work worth celebrating, not another three-paragraph LinkedIn post about how social media managers secretly have 20 different jobs. You can prompt AI to “make this sound more human,” “make it funnier,” or “remove the em dashes” all day long.

“People can still recognize when there’s a real person behind an idea, and the best content almost always reflects that.”

Therefore, businesses should focus on the powers of their own marketing and social media teams, rather than defaulting all creative work to AI. The technology can be useful, experts say, but for research or summarization, for example, and not the creative work.

However, studies have shown that audiences aren’t entirely against AI content, so long as it’s useful, personalized and relevant to them. Prioritizing this will help brands stay grounded in what will appeal to audiences.

At the end of our interview, I asked Alewine for his biggest tip for making content that lands with audiences: “Learn how to tell a story. Being able to tell a story is a form of communication that has been with humans throughout our entire existence. It resonates deeply within all of us.”
