Fellou: An agentic AI browser that automates deep search and cross-site processes, targeting knowledge workers.

I. Basic Information

Fellou is an agentic AI browser, primarily positioned to automate complex tasks across websites and applications using natural language descriptions, covering scenarios such as deep search, web page manipulation, data collection and processing, report generation, and scheduled execution. The product uses a browser as its platform, combining Browser Use and Computer Use capabilities to integrate web page automation with local applications and file management, providing visualized workflow planning, real-time intervention, and multi-task concurrency. Fellou also offers the Eko framework for developers, enabling the construction of reusable intelligent agent workflows using a hybrid approach of natural language and JavaScript.

II. Product Overview

Fellou operates on a "plan first, execute later" model. Users provide their goals in natural language, and the system generates a reviewable, step-by-step action plan, allowing for editing, approval, or intervention before and during execution. Its deep search covers public web pages and logged-in sites, supporting automated retrieval and data collection on platforms like Reddit and X, and storing the results in traceable, structured reports. For tasks requiring end-to-end processing, Fellou handles form completion, data transfer, code and documentation generation, forming a closed loop from data collection to delivery. Through Agentic Memory, the system understands user context based on browsing history, chat logs, and personal knowledge bases, providing more tailored suggestions and rapid retrieval.

III. Core Functions

1. Main functions

1. Deep search and traceable reports: Automatically retrieve information from multiple sources and integrate it into verifiable reports with rich graphics and text.
2. Cross-site automation and form manipulation: data transfer, login verification, automatic filling and submission across multiple websites.
3. Desktop-level workflow execution: Once authorized, you can operate local applications and files, and handle export, screenshots, and organization.
4. Visualized planning and real-time intervention: Displays the complete plan and steps, allowing users to view progress and pause or modify at any time.
5. Multimodal generation: Generates images, music, PPTs, tables, and front-end code in the task.
6. Task scheduling and concurrency: Supports scheduled and cyclic execution, providing concurrent operation capabilities to improve throughput.
7. Developer extensions: Use the Eko framework to build reusable proxies and tools, integrate with multiple mainstream large models, and switch between them quickly.

2. Technical characteristics

1. A layered strategy of planning before execution improves interpretability and stability.
2. Visual interactive element extraction and efficient webpage parsing significantly reduce the size of the context and the cost of calling it.
3. The Hook mechanism and tool system facilitate the monitoring, interception, and intervention of task execution in a production environment.
4. Personalized contextual understanding and long-term memory enabled by Agentic Memory.
5. The hybrid arrangement of natural language and programming language promotes the modularity and reusability of workflows.

VI. Platform and Acquisition

Currently, only macOS-based installation packages are available, differentiated by Apple chip and Intel chip versions. Support for other desktop platforms is uncertain; please refer to official updates for details. Users can obtain the browser installation package from the official website and log in and subscribe within the product.

VII. Frequently Asked Questions

Q: What are the fundamental differences between Fellou and traditional chat-based assistants?

A: Fellou focuses on browser and desktop automation, emphasizing the ability to execute from goals to actions. It can complete tasks across multiple websites and local applications, and supports concurrent and scheduled execution.

Q: Can Fellou handle sites that require login or verification codes?

A: It supports login and verification processes under compliance conditions, and has the ability to handle CAPTCHAs and identity verification to ensure the continuity of cross-site automation.

Q: How is Fellou's "interventional workflow" reflected?

A: Each task will display a visual plan, and the execution process can be viewed and paused in real time. Users can modify or terminate any step, ensuring that the process is transparent and controllable.

Q: Can the task be executed on a scheduled or recurring basis?

A: Supports setting timed or periodic plans for complex workflows, used for automation scenarios such as periodic report generation and indicator monitoring.

Q: How can developers extend Fellou's capabilities?

A: Custom agents and tools can be created using the Eko framework, employing a hybrid orchestration of natural language and JavaScript, and integrating mainstream models to adapt to different task requirements.
