The idea for Fellou began with a simple but daring question, what if a browser could do more than just open pages? Conceived as a response to the limitations of traditional web browsing, its creators imagined a tool that could think, adapt, and assist. After months of development, Fellou was introduced in mid-2025, positioning itself as the world’s first agentic browser.
Most browsers just render pages and get out of the way, but Fellou tries to act on your behalf. Give it a goal (“find competitive pricing, collect specs, draft a brief, and prep an email”) and it plans steps, opens tabs, reads pages, clicks buttons, fills forms, and compiles a result.
It wasn’t born to compete with existing browsers on speed or design alone, but to redefine their purpose. With Fellou, the goal was to shift the browser’s role from simply displaying content to actively assisting in navigating the online landscape.
What’s Actually Inside Fellou?
Fellou’s core falls into four buckets:
1. Deep Action and Workflow Automation
Fellou sequences tasks, like opening source pages, reading content, interacting with forms, downloading files, and producing a report, without the user micromanaging every step. It shows work in a “virtual” or shadow window so your main workspace isn’t constantly flickering.
2. On-Page Intelligence
Point Fellou at a page and ask questions, or summarize the article, extract dates and prices, translate a section, or cross-reference across open tabs. Community write-ups repeatedly highlight “website Q&A” as a useful baseline feature.
3. Triggers and Custom Agents
Fellou’s website markets event-driven automations (like responding when a page updates or a system event fires) and the ability to build reusable “agents” that run those workflows for you. For developers, Fellou advertises hooks into browser/OS APIs and a no-extra-client approach, exposing “computer use” capabilities via JavaScript and letting users access them by installing Fellou.
4. Security Posture
Fellou runs on your device with your login, and avoids sharing credentials with remote services. The sensible design for agentic tools, look for independent auditing as the product matures.
What’s New Right Now?
On August 12, 2025, Fellou issued a press release for a “Next-Generation Agentic AI Browser,” emphasizing workplace automation and a feature called Agentic Memory, positioned to personalize help and improve over time. Typical release language aside, the timing signals active development and a push beyond early adopters to business workflows.
The User Experience
If you want a quick sense of the UX without installing anything, several hands-on demos show Fellou planning a task, opening a flurry of tabs, extracting information, and generating a human-readable brief. These are not lab benchmarks, but they’re helpful to gauge maturity and friction points.
On the community side, a Reddit write-up calls out practical workflows like composing emails, creating social posts, or even making a purchase end-to-end, but aligned with Fellou’s stated capabilities. A Show HN discussion presents Fellou as going beyond search to generating reports, helping edit them, and capturing content through dev tools.”
Fellou’s branding strongly emphasizes its claim of being the “first” in its category. However, it enters a space already explored by other AI-driven browsers, such as Perplexity’s Comet, the Browser Company’s Arc and Dia, and AI copilots built into mainstream browsers. What sets Fellou apart is its focus on native autonomy, performing actions rather than merely providing answers, and its developer-centric approach to enabling computer use directly within the browser.
While this is a notable differentiator, verifying the “first” label is challenging without standardized benchmarks and a clear historical timeline. For now, the claim is best viewed as strategic marketing until more independent, side-by-side comparisons emerge.
A recent HN discussion comparing agentic approaches suggests that DOM-aware, programmatic interaction can outperform “vision-only” page control in some scenarios. That isn’t specific to Fellou, but it hints at why implementation details matter more than slogans when you evaluate any agentic browser.
Where Fellou Could Be Useful Today?
Fellou’s agentic approach to browsing opens up practical applications across different workflows.
- For researchers, it can quickly scan multiple sources, extract relevant details, and compile them into organized summaries or reports, saving hours of manual tab-switching.
- Operations teams could benefit from its event-triggered workflows, automating repetitive tasks like tracking shipments, gathering analytics, or updating dashboards.
- Content creators and marketers might use it to draft emails, blog posts, or social updates based on fresh data it gathers in real time.
- Even for individual users, Fellou’s ability to act, rather than just display results, means everyday tasks like comparing products, booking services, or managing online accounts can be completed with minimal input. Fellou bridges the gap between search and execution, making it a versatile tool for both professional and personal productivity.
Availability and Pricing
Fellou is available through its official website https://fellou.ai, where users can either download the browser or join an early-access program. Depending on your region and rollout phase, you may encounter a waitlist before receiving access. The site also provides basic product overviews, feature descriptions, and entry points for developers interested in building custom agents. Fellou’s team occasionally shares updates via press releases, blog posts, and social media channels, making these good sources for tracking new builds and feature rollouts.
Fellou uses a credit-based system, with a tiered structure that offers both a free starter allotment and paid credit packages:
- New User Bonus
You start with 5,000 free credits. On the 1st of each month, if your balance dips below 2,000 credits, Fellou automatically refills it to 2,000.
- Credit Package – $20 (Popular)
Purchases 2,000 credits, estimated to enable up to 5 workflows.
- Credit Package – $50 (Best Value)
Offers 5,000 credits, roughly estimated for up to 12 workflows.
Fellou notes that actual credit consumption varies depending on workflow complexity, so these estimates are just a general guide.
How Fellou Compares to “AI in Your Browser?”
If you’ve tried assistant sidebars in Chrome, Edge, or a research tool that summarizes pages, Fellou’s difference is the action layer. Instead of helping you read a page, it tries to finish the job, fetch data across many pages, transform it, and take the next steps (compose, fill, submit). It’s closer to a desktop automation companion wrapped in a browser UI than a search helper.
If your work is a string of web tasks, open, search, filter, export, email, Fellou’s ceiling looks higher than a typical sidebar chatbot. The tradeoff is complexity and the need for guardrails when actions have consequences.
Agentic software is moving from novelty to utility, and Fellou is a clean test case of what that future might feel like. It unifies planning, browsing, and acting under one roof; it courts developers with browser or OS hooks; and it’s starting to communicate a roadmap geared to real work, not just demos. If you’re curious, watch a couple of recent demos, skim the HN thread for counterpoints.
Fellou is more than a browser, it’s a step toward an AI-powered web that works for you. With its agentic design and automation-first approach, it offers a glimpse into the future of online interaction. While its “first” claim will face competition, Fellou’s vision is already reshaping how we think about browsing.
