Carosello vs aiCarousels: AI-Generated Images or Templates?
LinkedIn carousels earn 278% more engagement than text posts (Buffer, 2025), and custom visuals are the single biggest reason the format performs — carousels drive 11.2x more impressions than text updates (Sprinklr, 2025). Carosello and aiCarousels both target this opportunity with very different strategies: aiCarousels relies on pre-designed templates and stock imagery, while Carosello generates original images from scratch using Google Gemini AI.
This guide compares both tools across features, image quality, pricing, and workflow so you can pick the right carousel generator for your LinkedIn content strategy.

The Fundamental Difference: Templates vs AI Generation
The most important distinction between these two tools is how they create visuals. aiCarousels provides a library of professionally designed templates that you fill with your own text, colors, and stock photos. The output is polished but inherently shared — other aiCarousels users may produce similar-looking carousels using the same templates.
Carosello takes a generative approach. Its Image Laboratory, powered by Google Gemini, creates original images from text prompts. You can provide reference images for style guidance, combine two references with dual-reference mode, and fine-tune results with retouch mode. Every carousel is visually unique because the images are generated fresh each time.
Neither approach is universally better. Templates offer predictability and speed, while AI generation offers originality and creative flexibility. Your choice depends on whether you value consistency with proven layouts or the ability to create something no one else has.

Carosello's BYOK model is unique in the carousel generator space. By bringing your own Google Gemini API key, you can create unlimited carousels with AI-generated images at no cost beyond your own API usage (typically a few cents per carousel). For users who prefer managed pricing, Carosello's credit packs start at just €4 with no expiration date and no recurring fees.
The Verdict
Carosello and aiCarousels both solve the same problem — creating LinkedIn carousels quickly — but they take opposite approaches. aiCarousels is ideal for creators who want proven, template-based designs they can customize with their own content. It is fast, predictable, and removes the need for design decisions.
Carosello is built for creators who want original visuals that stand out in the feed. Its AI image generation, dual-reference compositing, and retouch mode give you creative tools that no template-based generator can match. The trade-off is that generative output is less predictable than templates, though the retouch mode helps you refine results quickly.
On pricing, Carosello has a clear edge. Its BYOK free tier and one-time credit packs (starting at €4) make it accessible to individual creators, freelancers, and small teams who cannot justify another monthly subscription. If you are creating carousels regularly and want your content to look genuinely different from everyone else's, Carosello's generative approach is worth exploring.
Frequently Asked Questions
What is the main difference between Carosello and aiCarousels?
The core difference is in how visuals are created. aiCarousels uses pre-designed templates and stock imagery that you customize with your text. Carosello generates original images from scratch using Google Gemini AI, with features like dual-reference compositing and retouch mode. This means Carosello carousels are unique every time, while aiCarousels carousels share template designs with other users.
Does aiCarousels have AI image generation?
No. aiCarousels uses a template-based approach where you select from pre-designed layouts and add your own text and stock images. It does not generate original images with AI. Carosello includes a full Image Laboratory powered by Google Gemini that creates original images in 10 different aspect ratios, supports dual-reference image generation, and offers a retouch mode for fine-tuning results.
Can I use Carosello for free?
Yes. Carosello offers a completely free tier through its BYOK (Bring Your Own Key) feature. If you have a Google Gemini API key, you can use all of Carosello’s features at no cost — the only expense is your own API usage, which is typically pennies per carousel. Paid credit packs start at €4 for users who prefer not to manage their own API key. aiCarousels requires a paid subscription with no free tier or BYOK option.
Which tool is better for brand consistency across carousels?
Carosello offers more granular brand control with 16 color slots per brand palette, ensuring every slide matches your brand identity. aiCarousels provides some template customization but is limited by the design constraints of each template. If maintaining a distinctive, on-brand visual identity across all your carousels is important, Carosello gives you more control over colors and visual style.
