Plan-first execution
Fellou analyzes a goal and produces a step-by-step plan before it starts acting. Users can review, approve, or edit that plan, which helps keep multi-step work understandable and controlled.
Fellou
認証するFellou is an agentic AI browser for deep search, browser automation, and cross-app task execution. It includes a free tier, paid plans, and desktop downloads for Mac and Windows.
Overview
Fellou is an agentic AI browser built for deep search, cross-site automation, and task execution. The site positions it as a self-driving browser that does not just answer questions; it analyzes a goal, plans a workflow, and then acts across websites and desktop apps.
The product is aimed at people who want to delegate repetitive research and online work such as competitor analysis, report compilation, form filling, data transfer between tools, and scheduled workflows. It also supports review and intervention during execution, so users can supervise the agent instead of handing over control blindly.
Core features
Deep search and report generation
The browser can run deep research across the web, including logged-in sources such as Reddit or X, and turn that research into traceable reports with sources.
Browser automation
Fellou can automate end-to-end browser workflows such as data scraping, form filling, and other repetitive web tasks from a single command.
Desktop file and app control
The product extends automation to local apps and files through its computer-use capability, allowing it to operate at the system level with permission.
Real-time oversight
Users can intervene during a workflow, inspect what the agent is doing in real time, and stop or adjust the task when needed.
Multimodal agents and memory
The site also describes multimodal outputs and agent types for image, music, and code creation, along with browser history-based memory for context.
Representative use cases
Competitive research
Use Fellou to gather competitive information, compare features, and compile the findings into a structured report with traceable sources.
Cross-app workflow automation
Use the browser to move data between websites and apps, such as copying information from one platform into another or preparing updates from notes to email.
Repetitive browser operations
Use Fellou for routine web tasks like scraping, form filling, and repeated account work that would otherwise require many manual clicks.
Multi-source reporting
Use the agent to pull together updates from multiple sources, including logged-in sites, and turn them into a research brief or summary document.
Browser plus desktop tasks
Use the desktop-capable workflow to handle local files and app interactions alongside browser actions when a task spans both web and computer use.
Pros and Cons
Pros
- Plans work before acting, which makes multi-step automation easier to inspect and correct.
- It supports deep research plus execution, so users can move from finding information to producing reports and taking action in one flow.
- The browser can operate across websites and desktop apps, not only within one web app.
- Users can monitor, edit, or intervene while a task is running.
- The pricing page shows a free tier and paid plans, which gives users a low-friction way to try the product.
Cons
- Pricing is usage-based through Sparks, so actual task coverage can vary with workflow complexity.
- Some capabilities are described broadly on the site, but the public pages provide limited technical detail about integrations and supported services.
- The product is still browser-centered, so tasks that require very specific third-party handling may depend on how well the agent can navigate the target site.
FAQ
How is Fellou different from a normal AI chat assistant?
Fellou is an AI browser that can plan and execute multi-step work across websites and desktop apps. Unlike a chat assistant that only responds, it is designed to carry out tasks such as research, data collection, and cross-app workflows.
What kinds of tasks can Fellou handle?
The source describes Fellou as handling complex web automation, deep research, browser use, computer use, image and music generation, and code creation. It is positioned for work that goes beyond page summaries or tab organization.
Can I control what Fellou does before it runs?
Yes. The home page says Fellou shows a task plan before execution, and users can review, approve, edit, or intervene during the workflow. That makes the automation more transparent than a fully hidden background process.
Can Fellou work across different apps and websites?
Yes. The FAQ on the site says Fellou can automate workflows across apps and websites, including pulling data from one platform and using it in another. It is presented as broader than tools that rely only on a single API connection.
What platforms does Fellou support?
The download page offers separate Mac and Windows downloads. On Mac, it distinguishes between Apple silicon and Intel versions.
