How the AI Comparison Tool Works Behind the Scenes

This AI model comparison tool isn’t just visually clean, it’s also powered by a smart, custom-built script that makes the entire experience fast, dynamic, and interactive. Let’s break down how it works in simple terms:

Custom Code That Powers the Tool

The comparison tool is built using custom JavaScript code that performs multiple functions to make the site feel smart and dynamic. Here's what the code does behind the scenes:

1. Pulls Data from an API

• The code connects to a backend API where all the model data is stored.
  
• It fetches all the AI model information like name, release date, use cases, model type, pricing, etc.
  
• Even if data is missing (like GPT-5 in some APIs), the script automatically adds it.

2. Dynamic Model Search

• You can type in the model name (like GPT-4.1, Claude 3, Gemini), and it shows suggestions.
  
• It avoids showing duplicate comparisons (you can’t select the same model on both sides).
• It even handles keyboard navigation with the arrow keys and the “Enter” key for faster selection.

3. Smart Table Population

• Once you select a model, the script fills in the entire comparison table with that model’s details.
  
• You don’t have to refresh the page, it’s instant!
• It supports comparing one or two models side-by-side.

4. Auto-Updates URL for Sharing

• This means you can share the link, and others will see the same comparison directly.
• The tool updates the URL with the selected models using query parameters like: ruby

Code

?model1=GPT-5&model2=GPT-4.1
      

5. Updates Page Title & Meta Description

• The script updates the SEO metadata like page title and meta description, based on your selected models.
  
• This helps with better visibility on Google and social media sharing.

6. Generates Custom Sitemap

• A special feature lets you generate and download an XML sitemap.
  
• This includes comparison URLs for all possible model pairs.
  
• It’s great for SEO indexing and keeping search engines updated.

Handles Edge Cases

• If a user types a model that doesn’t exist, it shows a friendly message.
  
• If no models are selected, it defaults to showing GPT-5.
  
• It also ensures accessibility by supporting both mouse and keyboard interactions.

Why We Used Custom JavaScript Instead of Plugins

Even though Webflow is a no-code/low-code platform, we used custom JavaScript for this tool because:

• We needed more control and flexibility.
  
• Webflow CMS couldn’t handle dynamic table comparisons out of the box.
  
• This approach allows us to scale, add new models, or features without redesigning everything.

1. Planning the Tool: Features & Scope

• Features required:
  
  • Dynamic list of AI tools/models
    
  • Search & filters (e.g., by type, cost, modality)
    
  • Comparison feature
    
  • SEO-friendly pages
    
• Target audience: developers, product managers, AI researchers

2. Creating the Layout in Webflow

• Design a clean layout using Webflow Designer
  
• Use Collection List for CMS Items
  
• Include a filters section at the top
  
• Add a compare checkbox or button
  
• Add mobile responsiveness
  
• Screenshot the layout structure from Webflow Designer

3. Custom Code Integration

Embed custom JavaScript to enable:

• Dynamic Filtering (by tag/category)
  
• Real-time Comparison Logic
  
• Local Storage to Save Compared Items
  
• Dynamic URL for Comparison (e.g., ?compare=model1,model2)
• Explain how scripts are added in Webflow settings (Page Settings > Before Body Tag)

4. SEO Setup

• Use Webflow’s dynamic SEO tags for CMS pages
  
• Set up Open Graph image, dynamic title, and description
  
• Add structured data (JSON-LD for Product or SoftwareApplication)
  
• Show example: ( random example is here )

Code

<script type="application/ld+json">
{
  "@context": "https://schema.org/",
  "@type": "SoftwareApplication",
  "name": "ChatGPT",
  "operatingSystem": "Web-based",
  "applicationCategory": "AI Assistant",
  "offers": {
    "@type": "Offer",
    "price": "Free",
    "priceCurrency": "USD"
  }
}
</script>
      

5. Generating Dynamic Comparison Pages

• Explain how to use query parameters (?compare=a,b) to load multiple CMS items and compare them
  
• Mention logic: fetch data using CMS item slug
  
• Use JavaScript to parse the query, fetch CMS content, and render the comparison layout

6. Deployment & Testing

• Test on multiple devices (mobile/desktop)
  
• Test CMS binding and dynamic logic
  
• Test filter combinations and comparison limits (3 max, for example)
  
• Add real screenshots of the testing phase

7. Lessons & Future Improvements

• Add potential ideas:
  
  • Filter by performance benchmarks
    
  • User reviews
    
  • Auto-recommendation based on user needs
    
• Add GA/GTM tracking to track interactions

Challenges We Faced in AI Compare Tool Development in Webflow

Building the AI Model Comparison Tool in Webflow was fast and efficient, but it wasn’t without its challenges. One of the biggest hurdles we faced was dynamic sitemap generation, something Webflow doesn’t natively support. Here’s a breakdown of the challenges and how we solved them.

Dynamic Sitemap Generation Error in Webflow

The Challenge:

‍Webflow automatically generates only one default sitemap for the website. But our AI comparison tool creates hundreds of dynamic URLs (for example: /compare-ai-models?model1=GPT-5&model2=Claude-3) These dynamic pages were not getting indexed in search engines because Webflow doesn’t allow adding or managing a second sitemap file.

The Solution:

‍We solved this using custom JavaScript code.

• The script automatically generates all possible model comparison URLs.
  
• It then creates a custom sitemap.xml file dynamically.
  
• Users (or admins) can also download this sitemap with a single click.
• This ensures that all comparison pages are properly indexed by Google and other search engines.

Custom Sitemap Hosting Challenges

The Challenge:

‍Even after generating the custom sitemap, Webflow did not allow us to upload or host it directly as a second sitemap on the main domain. This was a limitation of the Webflow platform.

The Solution:

‍We used a workaround:

• The custom sitemap was hosted on a separate subdomain (for example: sitemap.zignuts.com).
  
• This gave us flexibility to manage, update, and serve the sitemap outside Webflow’s restrictions.
  
• Search engines could now crawl all our AI model comparison URLs.
  

Key Takeaway

By combining Webflow’s CMS capabilities with custom JavaScript scripting, we managed to:

• Generate a fully dynamic sitemap for hundreds of AI model comparisons.
  
• Overcome Webflow’s limitation of only one sitemap.
  
• Improve SEO by ensuring all comparison URLs are discoverable.
  

This was one of the biggest technical wins in making the AI Model Comparison Tool both user-friendly and search engine–friendly.

Final Thoughts

Webflow helped the team build a fast, flexible, and data-friendly AI comparison tool without the need for a full backend or complex custom code. It's the perfect platform for launching tools quickly, while keeping the design modern and the experience smooth for users.

If you're planning to build an AI-powered solution or are just curious about which model is better, this comparison tool gives you everything at a glance. No more guesswork or hours of research.
