Fellou is an “agentic browser” in which an AI agent operates the browser on your behalf. Where a traditional browser is a tool a person drives, Fellou takes a goal written in plain language and then opens pages, searches, clicks, gathers the data it needs, and compiles the result into a report on its own. It offers Deep Search for cross-site research, Workflow for reusing routine procedures, and scheduled execution for running tasks at a set time. Progress is visualized on screen, so you can stop the agent mid-run and redirect it. Fellou is developed by Fellou, a US company. It launched in May 2025 and is currently distributed as a Chromium-based desktop app for macOS (Intel and Apple Silicon).
Key Features
- Browser operation driven by natural language: Write a goal such as “research this product’s competitors and build a comparison table,” and the agent handles the page navigation, input, and clicking itself before summarizing the result. You no longer repeat the same steps by hand
- Cross-site research with Deep Search: Instead of summarizing a single set of search results, it opens multiple sites in sequence, collects information, and outputs a report with sources. It can also work on pages behind a login, reaching material that ordinary search engines cannot
- Visible execution plans and mid-run intervention: Before running, it presents a plan of how it intends to proceed, which you can review and edit. Each step is displayed while it runs, so you can stop it the moment it deviates from what you expected
- Workflow and scheduled runs: A procedure that worked once can be saved in reusable form and set to run automatically at a specified time — a good fit for recurring information gathering and monitoring
- Desktop and file operation (Computer Use): It goes beyond the web to work with local applications and files, so collecting information and writing it out to a file can happen in one continuous flow
- Chromium compatibility: Built on Chromium, it feels close to the browser you already use. For developers, documentation for Eko, a framework for building agents, is also published
Pricing
Alongside the free plan there are three paid tiers based on usage credits called Sparks. Annual billing is roughly 20% cheaper than monthly.
| Plan | Monthly | Annual | Usage guideline |
|---|---|---|---|
| Free | $0 | ─ | 1,000 Sparks first-time bonus, 2 scheduled tasks |
| Plus | $19.00 | $192 (about $16/month) | 2,000 Sparks/month, 3 scheduled tasks |
| Pro | $39.90 | $384 (about $32/month) | 5,000 Sparks/month, 5 scheduled tasks |
| Ultra | $199.90 | $1,920 (about $160/month) | Unlimited Sparks (limited time), unlimited scheduled tasks |
Spark consumption varies considerably with the complexity of the work, so the task counts above are only a rough guide. The main capabilities — chat, Deep Search, browser operation, and desktop operation — can all be tried on the free plan.
Pricing is current as of August 2026. Check the official site for the latest information.
Pros & Cons
✅ Pros
- The whole manual chain of searching, browsing, collecting, and organizing can be delegated, cutting research time substantially
- Because it can operate pages behind a login, it reaches information that general-purpose search AI cannot retrieve
- The plan and progress are visible, so you are less likely to be left wondering what the AI actually did
- The free plan covers the main features, and successful procedures can be reused as Workflows
- Being Chromium-based, switching from your current browser takes little adjustment
⚠️ Cons
- Official distribution is currently macOS only, so it cannot be installed if you work primarily on Windows
- The Spark credit system means repeated complex tasks can hit the limit sooner than expected
- Since the agent operates logged-in pages by itself, handling work accounts calls for care around permissions and data
- Runs can fail partway when a target site changes structure or demands a login
- As a relatively new product, features and pricing may keep changing

Agentic browsers are a fast-moving category, so treat this table as a rough characterization as of August 2026.
Who Is It For
- People who routinely face work that means repeating the same operation dozens of times — competitive research, market research, information gathering
- People who want more than summarized search results, and would rather have the sites actually opened and the data actually collected
- People who want to automate recurring duties such as gathering information at a fixed time and turning it into a report
- Cautious users who want to delegate operations to AI while still watching what it does
- macOS users who do not mind adopting a new browser
Summary
Fellou moves one step beyond “ask the AI” toward “have the AI operate for you.” Deep Search across multiple sites, Workflow for reusing procedures, and scheduled execution for recurring duties add up to a setup that pays off most for people whose work centers on research and information gathering. On the other hand, it is worth understanding up front the credit-based usage cap, the macOS-only distribution, and the operational care required when the agent works with logged-in sessions. A good way to start is on the free plan, handing it one of your own routine tasks.
