Comparative Analysis of AI-Powered Browsers

Four browsers are revolutionizing our browsing experience with impressive agentic features. They interpret natural language, plan, and execute actions autonomously. This analysis focuses on Comet, Fellou, Genspark AI Browser, and Opera Neon, each presenting distinct advantages.

Comet: The Perplexity Browser

Comet is rolling out progressively, utilizing the Chromium base code and integrating Perplexity as the default search engine. This browser, designed by former Google AI employees, is recognized for its efficiency. Its sidebar allows for smooth interaction with the browsing environment and various features.

The memory module manages a local history while executing tasks such as auto-filling forms or managing shopping carts. Through natural language commands, the user can, for example, request: “check my calendar and suggest three time slots for a meeting.” The integrated connectors include popular applications like Gmail and WhatsApp.

Comet offers an accessible freemium model, with a Pro subscription at $20/month before tax providing advanced features. The “Max” version, at $200/month before tax, allows unlimited access to Perplexity’s resources.

Fellou: The First Agentic Space Browser

Fellou emerges as the first agentic space browser, offering a revolutionary interface. It boasts a 72% success rate on complex automation tasks, surpassing other renowned browsers. Users can accomplish various tasks, including creating visual reports and organizing documents.

Custom workflows, through the Eko framework feature, enable the creation of complex agents. This browser aims to automate actions on platforms like Notion or LinkedIn. Despite these promises, many features have proven unstable during initial testing.

Fellou has a freemium model, with limited access to features. The “Pro” plan at $39.9 per month offers broader scheduled tasks compared to its basic model.

Genspark AI Browser: A Competitor to Chrome

Genspark AI Browser positions itself as a credible alternative to Chrome, with a strong reliance on AI. It operates like a traditional browser while having an integrated AI agent panel. The Autopilot mode automates various tasks without manual intervention, simplifying browsing.

This browser can chain actions like product comparisons or synthesizing customer reviews from forums. Equipped with multiple connectors, Genspark facilitates interaction with tools like Notion and Microsoft 365. However, the application’s vulnerability was highlighted during trials, revealing security flaws.

The free plan of Genspark is limited. The “Plus” option at around $20 per month provides priority access to AI agents and new features.

Opera Neon: An Experience for Aficionados

Opera Neon has been designed for users passionate about AI. It offers several AI agents: Neon Chat for classic support, Neon Make for project creation, and Neon Do for semi-autonomous actions. These agents position Opera Neon as a powerful tool for work organization.

Features include the ability to jump directly to a specific scene in a YouTube video through specific commands. The Cards feature allows for product comparisons by integrating ready-to-use prompts.

Despite this browser’s impressive capabilities, the interface has shortcomings in terms of intuitiveness. Access is by invitation only, with subscriptions starting at $20 per month.

Security Issues and Pricing

Each browser has security concerns. Comet is vulnerable to phishing attacks, while Fellou advocates a “Privacy-First” approach but remains exposed. Genspark has displayed flaws in the Android application, and Opera Neon offers an integrated VPN but with a sometimes confusing interface.

Pricing varies, ranging from freemium plans to more expensive subscriptions based on the desired advanced features. The competition among these browsers seems to be intensifying, each seeking to attract an audience eager for innovation.
