Hey there, creative human! 🌟 

Not long ago, creating viral content used to require a full team: a copywriter for hooks, a designer for visuals, a video editor for clips, and a strategist to coordinate it all.

Now? You need the right set of AI tools. But with hundreds of new AI products launching every week, finding what actually works is the real challenge.

After testing countless tools across client projects and my own content, I've narrowed it down to the essentials.

This curated toolkit covers 7 key areas of viral content creation:

Let's dive in! 🚀

🎨 Best AI Tool for On-Brand Social Media Visuals

Goal: Generate scroll-stopping social media visuals that maintain your brand's unique style. Create consistent ad images, promotional graphics, and campaign assets that align with your brand identity across all platforms.

Winner: Ideogram

Pricing: Plans start at $8/mo for Basic plan. Free plan available (limited credits and features).

Why it wins: Ideogram excels at pixel-perfect text rendering (essential for ads and promotional graphics) and brand style consistency through its Style References feature. Upload up to 3 brand images, and the model learns your aesthetic – color palette, composition style, design approach. Each style can be saved and applied to future generations, making it practical for marketers who need multiple variations of the same campaign visual without manual design work.

Best use cases:

Winner: ChatGPT (with Custom Instructions)

Pricing: Free tier available. ChatGPT Plus at $20/mo unlocks GPT-4o, longer context, and priority access.

Why it wins: ChatGPT's versatility and context understanding make it the most powerful script generation tool when paired with effective prompts. It can analyze trending formats, adapt tone for different platforms (TikTok vs. LinkedIn), and generate multiple hook variations for A/B testing. The "Absolute Mode" prompt eliminates fluff and delivers direct, conversion-focused copy.

Best use cases:

  • TikTok/Reels hooks that stop mid-scroll

Why it wins: Memelord combines two essential meme workflow needs in one ecosystem: memelord.com for AI-powered meme creation and memelord.blog for tracking trending topics in real-time. Instead of guessing which format is currently viral, the blog shows you what's hot right now, then the creation tool lets you generate your version instantly.
