Startup Fellou has launched Fellou CE (Concept Edition), a browser that the company says can interpret a user’s goal and autonomously carry out multi-step workflows across websites and apps, positioning it as the “world’s first agentic AI browser.”
Fellou CE is built around an automation engine called Eko 2.0, which the company claims achieves about an 80% task-success rate on the Online-Mind2Web benchmark—an evaluation suite for real-world web tasks. Eko 2.0’s performance represents a leap over the prior version and is presented as evidence the system can reliably execute complex sequences online.
The product emphasizes user oversight: Fellou says tasks progress in stages that users can approve or interrupt. A unified “memory” layer ties together browsing history, local/cloud files and prior interactions to maintain context across sessions. The company also highlights a “local-first, on-device” approach intended to keep sensitive data on user machines.
Alongside the browser, Fellou is rolling out Agent Studio, a marketplace for developers to build and monetize specialized agents that run within the system—part of a broader push to shift browsers from passive navigation tools to active task orchestrators.
Fellou’s launch follows a wave of interest in agentic AI interfaces and arrives with marketing that brands CE as a “spatial agentic browser,” introducing a Z-axis UI concept for arranging workspaces and agents. The company has promoted the claim across press materials and partner posts.
