Fellou Browser 2.0: Faster, more amazing, and more reliable than ever.
The only thing comparable is yesterday's Fellou.
In the Marvel Cinematic Universe, Jarvis is Iron Man Tony Stark's personal AI assistant, virtually omnipresent, providing support and help to Tony anytime, anywhere. Jarvis is not just a simple voice assistant; it is deeply integrated into Tony's life, managing his daily affairs, controlling his high-tech equipment, and even offering real-time tactical advice during battles. Jarvis's presence allows Tony to focus on more important matters, knowing he has a reliable assistant backing him.
Over the past month, we have carried out deep architectural adjustments and comprehensive optimizations for the Fellou browser. These improvements have not only enhanced performance and stability but also brought a smoother experience to users. Today, we are very proud to announce that Fellou 2.0 has taken a significant step towards our dream of a Jarvis-like general-purpose intelligent agent.
We hope Fellou is not just a tool but an intelligent partner that can integrate into users' daily lives. Our vision is for Fellou to become an indispensable part of users' lives, providing help and support anytime, anywhere, and not just a virtual assistant floating in the cloud.

Fellou's Next Steps
Why Agentic Browser?
An Agentic Browser represents a general-purpose intelligent agent based on a browser that can not only access the internet but also understand user needs and automatically break down complex tasks. Its original design intention was to allow the intelligent agent to deliver better results for users with their complete context, and we hope to fundamentally change how users interact with the web and computers.
Fellou relies on its unique Browser + Workflow + Agent architecture to pioneer this new category of Agentic Browser, creating a browser agent that can "auto-surf" like an "autonomous driving car".
Imagine no longer needing to switch between multiple applications to complete a task. Fellou can automate the entire process for you, from information gathering and data analysis to final task execution and result delivery. Whether it's market research, report generation, music creation, 3D design environment generation, or logo creation, Fellou provides end-to-end solutions.
Fellou's goal is to enable users to find happiness through Fellou's existence—the happiness of freeing their hands, liberating themselves from repetitive labor, and escaping the cubicle, computer screen, and office building—yet not abstaining from work. People find satisfaction in labor, and Fellou's existence is to allow people to do more dopamine-inducing work, while tasks that drain mental energy, patience, and physical strength can be left to Fellou.
Time is an irreplaceable resource for everyone, and giving people time and the freedom to be themselves is Fellou's original intention.
This is also the fundamental reason why we designed and developed Fellou and insisted on the Agentic Browser direction — we believe that the development of AI will accelerate more people's creative needs rather than reduce job opportunities. Humans and AI have a relationship of collaboration and achievement, not opposition. As a browser client on the user's local device, Fellou is that ubiquitous, responsive, and deeply integrated general-purpose intelligent agent that knows the user best, remembers the most, and understands their preferences.
With this expectation, we completed the Fellou 2.0 upgrade to deliver more and better results for users.
Fellou 2.0: Enabling AI Batch Production
Here's a summary of the 2.0 upgrade:
Faster: Reduced waiting, multi-tasking in parallel, more deliveries;
More Amazing: Diverse task delivery, 24/7 execution;
More Reliable: Production-grade coverage of diverse scenarios, success rate significantly increased from 31% to 80%;
Faster: Reduced Waiting, Parallel Multi-tasking, More Deliveries
Thanks to extensive, comprehensive, and multi-dimensional optimizations, Fellou 2.0 has achieved breakthrough progress in speed. Compared to Fellou 1.x versions, Fellou's execution speed for various tasks has increased by 1.2 - 1.5 times. Compared to some general-purpose agents, we have a significant speed advantage across different tasks, such as:
Task 1: Generate a 3D Minecraft scene with the Eiffel Tower.
Fellou Time Taken: 1 minute 20 seconds

A certain general-purpose Agent Time Taken: 4 minutes 30 seconds
Task 2: Convert "Fellou is the world's first Agentic Browser" into Morse code, then generate an audio file in MP3 format.
Fellou Time Taken: 1 minute 30 seconds
Fellou Deliverable:
A certain general-purpose Agent Time Taken: 2 minutes 30 seconds
Task 3: Create a Snake game using HTML.
Fellou Time Taken: 1 minute 20 seconds
Fellou Deliverable: https://chat.fellou.ai/sites/snake-game-classic-retro-fun-aiz5HkaM
A certain general-purpose Agent Time Taken: 6 minutes
Marketing Task (Cross-Application Productivity Workflow): Search Reddit/ Twitter / Youtube / Tiktok for posts about browsers published in the last week, and post comments to promote Fellou AI under these posts.
Fellou executed successfully.
Some general-purpose Agents failed to publish the generated promotional information to Twitter, LinkedIn, and other platforms, only generating the promotional information.
At the same time, we have optimized the multi-tasking parallel processing feature, allowing users to issue multiple tasks to Fellou simultaneously, greatly enhancing users' multi-threaded work capabilities:
Task A: Based on {@Youtube AI related videos}, create a website that summarizes the core knowledge of the video, including its main points, how it explains AI Agents and Agentic Reasoning, and its significance and application trends in AI development. The website should conclude with a few questions to test knowledge acquisition.
Task B: Use this {@Google Sheet bill} as a data source and generate a bill analysis website. The website should allow custom filtering from various dimensions.
Note: Parallel tasks are currently in the Alpha stage and will be significantly different in the official release.
More Amazing: Diverse Task Delivery, 24/7 Execution
By providing collaboration among diverse Agents (such as Browser Agent, Coding Agent, File Agent, Shell Agent, Computer-use Agent, etc.), Fellou offers a variety of deliverables beyond cross-application productivity workflows, including text, images, websites, PPTs, CSVs, Excels, Words, MP3s, video-to-speech conversions, logo generation, and YouTube video summaries.
Music Delivery Task: We're having a party tonight, and everyone wants to sing Jay Chou's songs, so help me find a few of his popular songs, then write some connecting chords or similar in between to string them together, and finally return the complete stitched accompaniment. A piano version is needed. Add some complex sound effects; I like experimental sound effects like Pink Floyd, or those Nujabes used to use.
Audio Delivery Task: Generate a complete set of feedback sound effects for smart home devices.
(Due to WeChat official account restrictions, this task does not provide a video)
Logo Delivery Task: Search for the architectural styles, culture, and imagery of Youxi County. Help me create a logo with the text "Youxi County Urban Tourism". Elements should include the image of Zhu Xi, the shape of a kumquat, and the landscape imagery of "eight mountains, one water, one field"—ideally, one element embodies all three meanings. The elements should be minimal to avoid appearing complex like a badge. The background should be white, flat, and simple. The Chinese text proportion should be 2x, English 1x, and graphics 6x. Colors should be strictly controlled within 2 colors, vector, flat, and aesthetically pleasing. Produce 10 designs in the style of Alan Chan, with one incorporating Youxi County's cultural heritage and imagery, another with the logo design style of Liu Bowen's former residence, and one integrating Zhu Xi's portrait.

In addition, Fellou 2.0 also provides ultra-long context management, especially for listening-type tasks (e.g., Slack, Discord new message monitoring, email monitoring, web content change monitoring), achieving infinite step length, truly solving long-process and complex scenario problems.
Monitor Gmail Task: Monitor my Gmail. When there's an email related to user product feedback, reply to the email in a friendly manner to express gratitude. At the same time, break down the user's mentioned requirements and bugs from the email and fill them into the {Airtable feedback form}.
Cross-border E-commerce Monitoring and Negotiation Task: Monitor SalesSmartly, answer user questions, guide users to complete orders. When users ask for prices, provide a quote according to the price list. When users ask for shipping time, provide an estimated delivery time based on the shipping schedule. When users negotiate prices, do not go below our bottom price, and continue communicating with users at the expected low price. Immediately generate a CSV order form (including: product name + quantity + unit price) once the user confirms the order.
Production-grade means closer to users' actual needs, more end-to-end, more unmanned, and closer to "reality," such as diverse scenario applications like information entry, data transfer, social media operations, closed-loop recruitment processes, and automated cross-border e-commerce negotiations.
People Search Task: Find the first five authors in the PDF I uploaded, then help me find all their background information and contact details. Background information includes Homepage, Google Scholar links, and Github links. Contact information includes email and phone number. You can find their commit emails by concatenating their Github Repo commit history URL with .patch, and find their emails and phone numbers on contactout.com. All links must be complete URLs.
Due to WeChat official account restrictions, the following cases cannot provide videos or GIFs for reference:
Marketing Task: Find 20 pet bloggers with 10k+ followers each on Twitter / Instagram / Youtube / Tiktok, and privately message them to inquire about collaboration for promoting Brand A cat food. Ignore YouTube if private messaging is not possible. Organize the blogger information into a web report.
Job Search Task: On BOSS Zhipin, find the latest posted Front-End Engineer positions. Based on the corresponding job descriptions and my uploaded resume content, write a self-introduction and send it to 10 recruiters via "Immediate Communication".
The above tasks are just the tip of the iceberg; more tasks await discovery, stemming from Eko 2.0's new architecture, which has boosted the task completion rate from 31% to 80% on the Online-mind2web leaderboard.
