Fellou: The Agentic Browser from Fellou AI

In a nutshell

Fellou is an Agentic browser built by the AI startup Fellou AI. It keeps the information-browsing capabilities of a traditional browser while adding intelligent task execution, turning tedious clicking into simple instructions and running tasks independently in the background.

What is Fellou?

Fellou is released by the AI startup Fellou AI, which positions it as the world's first Agentic browser. It retains the browsing functions of a conventional browser and layers intelligent execution on top: instead of clicking through steps one by one, you hand the task over with a single instruction.

In practice, Fellou parses the instruction, breaks the task down, and orchestrates operations across multiple web pages and systems; it predicts needs from your behaviour and proactively suggests actions; tasks run independently in the background without disturbing what you are doing; and you can use and share vertical-domain agents. Fellou also supports deep search, smart timeline, drag-and-drop interaction and sync tools.

Key features

• Deep Action: With a simple instruction, Fellou turns tedious clicking into an intelligent workflow — for example, filling out forms or managing tabs automatically.
• Proactive Intelligence: It proactively offers action recommendations and result suggestions, and builds a personal knowledge base from your activity to strengthen the personalised experience.
• Shadow Workspace: This intelligent workspace tracks and manages your activity in the background. You can monitor or intervene in the agent's behaviour in real time without it affecting your normal work.
• Agent Store: You get access to a wider range of vertical agent capabilities, and developers can package their experience, knowledge and workflows into agents for others to use.
• Cross-platform deep search: It supports parallel, batch searching across public web content and platforms that require sign-in (such as Quora, X and LinkedIn), and can generate a shareable visual report in one click.
• Cross-webpage task execution: It plans tasks, calls tools and executes operations automatically, coordinating across multiple web interfaces to handle in-browser tasks such as shopping, scheduling meetings, sending emails and posting updates.
• Context-aware browsing: It automatically recognises web pages opened in a conversation as context, lets you mark pages for comparison and analysis, and lets you drag images straight into the chat window with no copying and pasting.
• Asynchronous collaboration and parallel tasks: Tab groups let you switch to other work while the agent runs, and Fellou notifies you when the task finishes. Multiple tasks can be issued and handled in parallel.
• Diverse task output: It supports outputs such as files, images, websites and audio, and can run tasks automatically around the clock, 24×7.
• Ultra-long context management: It performs well in long, complex scenarios such as monitoring Slack, Discord, email and web page changes, effectively supporting an unlimited number of steps.

Technical architecture

Fellou combines three product capabilities — Browser, Agent and Workflow Automation — to close the loop between "thinking", "operating" and "executing". For developers, Fellou provides the Eko Framework, which lets you write, debug and optimise workflows in natural language.

How to use Fellou

1. Download and install: Visit the Fellou website (fellou.ai), click "Download", and pick the build for your device.
2. Launch the browser: Open Fellou after installation. First-time setup may include choices such as language and signing in to an account.
3. Deep search: Type keywords into the search box and Fellou returns deep search results.
4. Intelligent workflows: Give a simple instruction and let Fellou execute a complex workflow, such as filling in forms or managing tabs.
5. Drag-and-drop: Drag web elements or files into a designated area to trigger actions like uploading files or extracting information.
6. Shadow Workspace: Use Shadow Workspace so tasks run in the background without affecting what you are doing.
7. Agent Store: Browse the Agent Store to use agents shared by other users, or package your own experience into an agent for others.
8. Multi-task management: Use the timeline to switch between tasks and return to a previous working state.

Use cases

• Report generation: Produce a shareable visual report with a simple drag-and-drop action.
• Market research: Let deep search gather and organise information automatically and generate a detailed report.
• Behaviour prediction: Deep semantic understanding and contextual memory capture your activity across web pages and anticipate potential tasks.
• Personalised recommendations: A personal knowledge base built from your behaviour and habits drives a personalised experience.
• Everyday automation: Repetitive cross-page work such as shopping, scheduling meetings, sending emails and posting updates.

Who it is for

• Everyday users who want less clicking: People who would rather hand form filling and information lookup over to the browser.
• People doing cross-source research: Anyone who needs to search in batch across multiple platforms, including those requiring sign-in, and consolidate results into a report.
• Developers: Those who want to write, debug and optimise workflows in natural language and publish their own agents.

Summary

Fellou's core idea is turning the browser from a tool for reading information into one that carries out tasks. The Browser + Agent + Workflow Automation combination closes the "think – operate – execute" loop; a single instruction replaces tedious clicking; Shadow Workspace keeps background execution out of your way; and the Agent Store extends vertical capabilities. Compared with Fellou 1.x, version 2.0 executes different tasks 1.2–1.5 times faster. If you want a browser that does not just show information but does the work for you, Fellou is worth a look.
