1. Captivate by Sked
Coming in at #1 is the new Sked AI feature called ‘Captivate’. We LOVE this feature for a number of reasons. The new Captivate AI feature from Sked is an exciting and innovative way to generate social media copy, and the best part is, it's integrated into the one of the most popular social media scheduling platforms.

So, the future is officially here! (Almost). AI generators are able to support copywriting, inspire creative ideas and optimise copy for search engines. But, should you give your social media agency your notice? Definitely not! While our top 5 AI generators for social media posts may have great potential, there are so many aspects of your social media marketing strategy that need that human touch and expertise. Read about why social media agencies are still crucial, despite the emerging ability of AI.
New in 2025 / 2026: Emerging AI Post Generators to Watch
AI for social media has exploded since our original list came out. Today’s tools don’t just write captions — they analyze trends, design graphics, predict engagement, and even schedule entire campaigns for you. Here are five new AI generators shaping how marketers create in 2025 / 2026.
6. Buffer AI Assistant
Buffer’s AI assistant is perfect for busy marketers who want to create quick, on-brand captions without leaving their scheduling platform. Just add a topic or link, and it suggests fresh post ideas, hashtags, and tone variations.
Why we like it:
It feels like having a mini copywriter inside your scheduler, ideal for social teams managing multiple brands or accounts.
Pro tip:
Combine Buffer AI with its performance analytics to learn which caption styles perform best over time.
7. Hootsuite OwlyWriter AI
OwlyWriter is Hootsuite’s built-in caption generator, and it does more than just write posts — it recycles your top-performing content into new formats automatically. If you already use Hootsuite for scheduling, this integration is a no-brainer.
Why we like it:
You can repurpose your own content in seconds — turning a LinkedIn post into an Instagram carousel or a tweet thread with minimal editing.
Keep in mind:
It’s great for speed and consistency, but still needs a human check for tone and nuance.
8. Predis.ai
Predis has leveled up since our first review. It now offers trend analysis and multi-format creation — so you can generate carousels, short videos, or static posts from a single idea. It even suggests music tracks and color themes to match your brand.
Why we like it:
It’s like a creative director and social analyst in one. Perfect for brands that need a steady stream of relevant content.

9. SocialBee AI
SocialBee’s new AI suite goes beyond caption generation — it can outline an entire campaign from pre-made prompts. Just enter your goal (“launch a new product,” “grow followers on LinkedIn”), and SocialBee creates a month-long content calendar.
Why we like it:
Ideal for small businesses and agencies that want structure without spending hours in strategy mode.
Watch out:
It can feel templated if you don’t personalize the outputs — add your voice and brand tone for authenticity.
10. Jasper AI
Jasper is still a standout for social media writers who need depth. It combines AI-generated text, image prompts, and tone training in one dashboard. You can build brand voice profiles and train it on your existing content to keep your style consistent across posts and ads.
Why we like it:
It’s the closest thing to a virtual content team — great for marketers handling multi-platform campaigns who want to stay on-brand without micromanaging every caption.
Bonus tip:
Pair Jasper with a visual tool like Canva or Adobe Express to turn your AI-generated copy into scroll-stopping graphics instantly.
Conclusion
Exploring today’s best AI tools for social media can completely transform how you create and manage content. What used to take hours — from writing captions to designing visuals — can now be done in minutes with tools like Buffer AI, Predis.ai, and Jasper. Each platform has its strengths: some excel at automation, others at creativity or data insight.
Still, even the smartest AI needs a human in the loop. Algorithms can optimise timing, test formats, and analyse trends — but they can’t capture your brand’s story, humour, or values quite like you can.
At Born Social, we believe the sweet spot lies in combining AI efficiency with authentic human creativity. Let AI handle the repetitive tasks, but keep your voice and storytelling at the heart of your strategy. That’s how you’ll stand out in the noisy world of social media.
If you want to see how AI fits into your wider social strategy, check out our full guide on how to use AI for social media marketing — and discover even more options in AI tools for social media management.
Embrace the future of social media with AI — but remember, the most powerful marketing still starts with a human touch.
