Fellou AI Browser: Smarter Browsing with AI Agents

AI browsers are everywhere. Each new entry promises to change how we search, work, and browse. Fellou AI Browser is the latest to make that claim. But is Fellou truly different, or is it just another AI layer over Chrome or Edge? Fellou AI Browser was officially released on 11 May 2025 by Fellou Technologies, a European startup led by ex-DeepMind and Mozilla engineers with a vision for agentic productivity. A major update followed on 3 June 2025 with Fellou 2.0, boosting speed, reliability, and deep context-awareness. 

This browser is available for Windows and macOS. It offers a familiar interface. What really sets Fellou apart is its “army of AI agents” working behind the scenes. Fellou does not just add AI to web browsing. It introduces a new agentic architecture where multiple intelligent agents collaborate to handle complex tasks for you. Many are calling it a fundamental shift in how we interact with the internet. 

So, does Fellou AI Browser truly live up to its bold promises, or is it just more AI hype? Let us take a closer look at what it actually delivers. 

What is Fellou AI Browser? 

Fellou AI Browser is built around the idea of agentic computing. Instead of a single assistant, it puts an entire team of autonomous AI agents to work for you.

The browser uses contextual intelligence, meaning it understands what you are working on and coordinates different agents to help, often without you even asking. From the moment you open Fellou, you notice its clean and modern interface. But the real magic happens in the background.

As you browse, a network of AI agents reads, organises, and acts on information, streamlining your workflow and reducing manual effort. 

Agentic Deep Action: a new way to browse 

Fellou’s biggest leap is its Agentic Deep Action (ADA) framework. This is not just about smart search bars or AI sidekicks. ADA lets Fellou deploy multiple agents across platforms and tabs.

This means that when you need research done, reports prepared, or multiple sites monitored, Fellou’s AI agents handle it all. You no longer have to switch between fifteen tabs or copy-paste information. 

Built-in productivity for the agentic era 

Fellou goes beyond browsing and searching. Its built-in productivity features are tightly integrated with agentic automation.

There is a note-taking panel, a basic task manager, and a calendar view, all powered by AI agents. You can save entire web pages as notes and ask agents to summarise or tag them. The browser supports split-screen mode, which is perfect for comparing sources or tracking workflows.

Fellou also syncs tabs and settings if you sign in, so your AI agents can continue tasks across devices. 

Use cases: Who is Fellou for? 

Researchers are using agentic search to cut hours off their process, letting AI agents comb through academic papers and data.

Social media managers use Fellou’s agents to monitor multiple platforms and generate content summaries automatically. Professionals are automating repetitive tasks such as compiling news, updating dashboards, or scheduling emails, leaving agents to handle the boring bits. Even students benefit.

They can highlight a passage and let agents fetch references, translate text, or create summaries without leaving the page. 

The shadow window: True autonomous AI 

Perhaps Fellou’s most impressive feature is the “shadow window.” This is a hidden workspace where agents run in the background, handling multi-step jobs without interrupting your main browsing.

For example, you can ask Fellou to collect market data from several logged-in platforms. The AI agents will gather, sort, and visualise results while you keep working in your primary window. This is what true agentic productivity looks like.

Work continues, powered by AI, with zero tab overload and no lost research trails. 

Privacy, security, and trust 

With so much power, what about your data?

Fellou uses local processing for basic features and encrypted cloud services for agentic actions. Sensitive data, such as passwords, is not shared with Fellou’s servers. You control what agents can access, and privacy settings are clear and easy to adjust. However, Fellou is not open-source. While privacy is a focus, complete transparency is not possible.

If you handle sensitive work, check the privacy policy before diving in. 

Real-world use: Does Fellou deliver? 

Using Fellou AI Browser feels fast and fluid. The design is clean and the agentic features are truly handy for research-heavy or multi-tasking workflows.

The shadow window stands out, letting you hand off boring or repetitive tasks with confidence. There are still some rough edges. The agents can occasionally miss complex context, and the task manager is basic compared to full-featured apps. Heavy AI use can demand more from your system as well. 

Still, for users who need more from their browser with less manual work and more automation, Fellou feels like a real leap forward. 

How does Fellou compare to other AI browsers? 

Fellou is not the only AI-powered browser out there.

Rivals such as Arc, Opera with Aria, and Microsoft Edge with Copilot also offer AI assistants. Fellou is unique in making agentic computing with multiple autonomous agents, background tasking, and hands-free automation its core. While it still runs on the Chromium engine, the agentic layer on top feels genuinely new.

The main challenge will be convincing users to switch from their current browsers, especially with habits and plugins already in place. 

Should you switch to Fellou AI Browser? 

Fellou AI Browser is best suited for anyone who juggles research, content, or multi-platform work, such as researchers, professionals, social media managers, and students.

If you only browse social media or shop online, you might not see much value. For now, Fellou is free, though some advanced features may be paid for later. If you want to experience the future of AI-powered browsing, where the browser works for you instead of simply with you, Fellou is worth a try. 

Distilled 

Fellou AI Browser delivers on its promise of agentic productivity. By putting an army of AI agents at your disposal, it reduces manual tasks, organises research, and changes how you use the web. Its shadow window and deep automation are not just clever extras. They could be the start of a new way to work online. Fellou is not perfect, but it is more than just another wrapper. If you are curious about the next evolution of AI in your browser, Fellou AI Browser is leading the charge.
