Overview
Fellou describes itself as an agentic browser, meaning the browser is the agent. You type a task rather than a query, and it opens a shadow workspace in the background to navigate pages, click buttons, fill forms and pull data across sites while you keep using the main window.
Its capability splits into three layers. Deep Action handles cross-application workflows, turning one sentence into an execution plan you can edit before it runs. Deep Search retrieves across logged-in sites such as X and Reddit and returns a sourced report. Computer Use extends it beyond the web into local files and apps, so a workflow can pull a file from a download folder and upload it somewhere else.
Two more pieces matter. Agentic Memory accumulates context from browsing history, conversations and notes so a new task does not need the background explained again. Eko 2.0 is an open-source agent framework for people who want to assemble their own workflow and run it inside the browser. Scheduled tasks let it start on its own at a set time, which suits daily monitoring and recurring summaries.
Key Features
- Plan first, then act: A task becomes a step-by-step plan you can add to, trim or reorder before execution begins, and you can pause or take over at any point while it runs.
- Shadow workspace in parallel: Tasks execute in a separate background space, several at once without interrupting each other, while you continue browsing in the main window.
- Deep Search with logged-in sessions: It retrieves across sites where you are signed in, gathering material from X, Reddit and forums into a report with source links rather than summarising the top results.
- Computer Use on the desktop: With permission it operates local apps and files, connecting web tasks to local assets such as exporting from a folder and submitting elsewhere.
- Agentic Memory: It accumulates preferences and background from browsing history, conversations and notes, carrying that context into new tasks so briefs stay short.
- Scheduling and Eko 2.0: Common workflows can run on a timer for daily price or changelog monitoring, and developers can write their own agent logic with the open-source Eko 2.0 framework.
Use Cases
- Competitive monitoring that sweeps competitor pricing pages and changelogs every morning into a change list.
- Recruiting and sales research across logged-in sites, assembled into a spreadsheet instead of opened tab by tab.
- Matching web data against local files by having it export a table and read the download folder.
- Research collected across sites into a cited report, then checked line by line back in the browser.
- Repetitive expense, form-filling and submission flows recorded once and left to run on a schedule.
- Developers writing custom agents with Eko 2.0 that reuse the browser's page-control layer.
Pros
- Tasks produce a plan before acting, so there is a clear approval step.
- The shadow workspace runs several tasks at once without disrupting normal browsing.
- Retrieval works inside logged-in sessions, reaching material public search does not surface.
- Computer Use connects the web to local files, so workflows need not stop at the browser.
- Agentic Memory reduces repeated briefing on recurring tasks.
- Eko 2.0 is open source, so anyone who codes can extend it.
Pricing
Free is 0 dollars a month with 1,000 Sparks for new users, roughly four tasks, and two scheduled tasks; chat and deep search are available on every tier. Plus is 19 dollars a month with 2,000 Sparks, about eight tasks, and three scheduled tasks. Pro is 39.9 dollars a month with 5,000 Sparks, about twenty tasks, five scheduled tasks, advanced models and visual reports. Ultra is 199.9 dollars a month with unlimited Sparks and scheduled tasks plus unlimited concurrency. Annual billing saves about 20 percent. Browser Use, Computer Use, Image, Music and Code agents are available on all tiers and consume Sparks, with actual usage varying by workflow complexity.
Summary
Fellou picks a blunt entry point: instead of asking you to switch to an agent, it asks you to switch browser. Tasks run in a shadow workspace while the main window stays usable, which is less disruptive than leaving for a chat tab and coming back. Producing a plan before acting puts a checkpoint on the riskiest step, and deep search across logged-in sites is a real difference in retrieval. For anyone shuffling information across the web all day, the saving is in switching windows and re-explaining context.
Version History
