What Makes Perplexity AI Claude Sonnet 4.5 Different From ChatGPT

Perplexity AI Claude Sonnet 4.5 is connected to the internet.

ChatGPT has limited web access.

This difference is important for content creation.

When you ask Perplexity AI Claude Sonnet 4.5 to create content, it searches the web first.

It finds current information.

It uses multiple sources.

Sometimes 50+ sources and 20+ videos for a single piece of content.

Then it creates content based on this research.

The result is content backed by facts and current data.

The Comet Browser Announcement

Perplexity AI launched a new browser called Comet.

This browser has Perplexity AI Claude Sonnet 4.5 built directly into it.

The browser looks like Chrome.

You can import your Chrome data.

But it includes an AI assistant that can control your browser and perform tasks automatically.

Here’s what makes it special.

Email Automation With The Comet Browser

The Comet browser can send emails automatically.

I tested this feature.

I asked the Comet browser to email me about the latest Perplexity AI updates.

Here’s what happened:

1. It researched the latest updates

All automatically.

The email arrived with all the latest information about Perplexity AI Claude Sonnet 4.5 and other updates.

YouTube Video Analysis Features

The Comet browser can analyze YouTube videos in ways ChatGPT cannot.

Here are the features:

• Summarize the video
• Extract key takeaways
• Scroll to the next interesting moment
• Email you the notes

I tested the “scroll to next interesting moment” feature.

The AI analyzed the video content.

It identified the important parts.

It jumped directly to the key moment.

The video paused at the 43-second mark where I was explaining a specific feature.

The AI understood the video content and navigated to the most relevant part.

Extracting Video Insights Automatically

I also tested the key insights extraction.

I asked the Comet browser to extract key insights from a video.

It analyzed the entire video and created a summary with:

• Setup instructions
• Step-by-step process
• Benefits
• Pro tips
• Advanced features

Then I asked it to email me these notes.

It drafted the email and sent it automatically.

The email arrived with all the key points formatted clearly.

How The Browser Navigation Works

The Comet browser can control your browser.

This means it can:

• Navigate to websites
• Fill out forms
• Click buttons
• Read content
• Perform actions

When I asked it to scroll to an interesting moment in a YouTube video, it:

1. Analyzed the video content
2. Identified key segments
3. Moved the video timeline
4. Paused at the relevant moment

All automatically.

The AI can navigate YouTube faster than you can manually.

This is impressive because the AI has only been learning to use browsers for about a year.

Yet it already navigates better than humans in many cases.

Creating Facebook Ad Hooks With Research

• Amazing direct response examples
• Meta ad hooks that drive conversions
• Proven hook formats

Then it creates hooks based on these proven examples.

The quality is noticeably better.

The hooks are based on what actually works in the market.

The Five Hook Categories System

I split ad hooks into five categories:

1. Offer-driven (very direct)
2. Proof-driven (showing results)
3. Benefit-driven (focusing on outcomes)
4. Scarcity-driven (limited availability)
5. Curiosity-driven (creating interest)

Perplexity AI Claude Sonnet 4.5 creates hooks for all five categories.

Each category works for different audience temperatures.

Warm audiences respond to offer-driven hooks.

Cold audiences respond to curiosity-driven hooks.

Having hooks for all categories lets you test different approaches.

Real Ad Results From Hook Testing

I test multiple hooks for the same ad.

Same audience, same targeting.

Different hook.

The results vary significantly.

Hook one: $2.50 per lead

Hook two: $3.50 per lead

That’s a 40% difference in cost.

Just from changing the first 3 seconds.

This is why creating many hooks with Perplexity AI Claude Sonnet 4.5 is valuable.

You can test many variations quickly.

The Free Alternative To Paid Automations

Many automation tools cost money.

Tools like Lindy or N8N require setup time and monthly fees.

The Comet browser email automation is free.

You don’t pay anything to use it.

This makes automation accessible even if you’re on a budget.

The email feature alone saves hours of work.

I tested the email automation live.

It:

All in under 30 seconds.

Faster than any human assistant could do it.

This is the current state of AI automation.

And it’s only getting better.
