What Fellou does
Fellou is a privately held developer of the Fellou AI Browser, positioned as 'the world's first Agentic AI Browser' for deep search and task automation. The product autonomously plans and executes complex web and desktop workflows from natural-language prompts, combining three core capabilities: Browser Use for end-to-end web automation (data scraping, form filling, multi-step workflows), Computer Use for system-level local app and file control, and a Deep Action Agent that operates 24/7 with real-time user intervention. The platform supports logged-in account access on sites including Reddit, X, and Notion, and can solve CAPTCHAs, schedule recurring tasks, and run multiple jobs in parallel via a Shadow Workspace. An Agentic Memory layer personalizes assistance by learning from browser history, notes, and contextual page data.
The product portfolio also includes Eko 2.0, an open-source framework (JavaScript + natural language) released on GitHub for developers to build custom intervenable agents that run within the Fellou environment. Fellou is a featured developer building on Microsoft Windows 365 for Agents as part of Microsoft's 'Frontier Firm' vision announced at Ignite in November 2025, positioning the company inside Microsoft's enterprise AI agent ecosystem. The go-to-market is product-led: users download the browser directly from fellou.ai via a self-serve flow with a free tier and unspecified premium subscription. Customer segmentation is horizontal — data analytics, career, marketing, productivity, and developer audiences — with no disclosed named enterprise customers or institutional investors. Multi-modal generation (research reports, images, music, code, presentations, spreadsheets) extends the platform beyond browsing into content production.

Fellou competitors and assessment
Company assessmentDirect peers
- Manus AI: Manus AI builds autonomous general-purpose AI agents that execute multi-step tasks across the web, and was featured alongside Fellou as a developer partner on Windows 365 for Agents. The two companies share the same agentic-AI-for-task-execution positioning and target enterprise knowledge workers.
- The Browser Company: The Browser Company (maker of Arc and Dia) is building an AI-native browser that autonomously executes tasks on the user's behalf — essentially the same value proposition as Fellou. Both compete for the same users (productivity-focused knowledge workers) with browser-based agentic experiences.
- Genspark: Genspark is an AI search engine that generates custom Sparkpages and operates agentic workflows on behalf of users, comparable to Fellou's deep-research and automation features. Like Fellou, Genspark was featured as a Microsoft Windows 365 for Agents partner and targets users seeking AI-driven research automation.
- Perplexity AI: Perplexity AI is an AI-powered answer engine and is launching its own AI browser (Comet), making it the most direct competitor to Fellou in the agentic AI browser category. Both target knowledge workers seeking AI-augmented web search and task automation, and they share the same viral PLG motion.
Broad incumbents
- OpenAI (Operator): OpenAI's Operator is an agentic product that autonomously browses the web and executes tasks for users, directly overlapping with Fellou's Deep Action Agent. As a broad incumbent with massive model capabilities and ChatGPT distribution, OpenAI is both a competitive threat and a benchmark for Fellou's reported 3.1x speed advantage.
- Microsoft (Copilot in Edge): Microsoft embeds Copilot agentic capabilities directly into the Edge browser and is Fellou's strategic partner on Windows 365 for Agents. While Microsoft is currently a distribution partner, Edge represents both a major future distribution channel and a potential long-term competitor in the agentic browser space.
- Google (Gemini in Chrome): Google is integrating Gemini-powered agentic capabilities directly into Chrome, which would compete with Fellou at the OS-level browser distribution layer. As the dominant browser vendor with billions of users, Google represents the most significant incumbent threat to any standalone AI browser.
Emerging players
- MultiOn: MultiOn is an AI agent platform that autonomously browses the web and executes tasks on behalf of users, comparable to Fellou's Deep Action Agent. As an earlier-stage competitor, MultiOn focuses on personal AI agent use cases with similar agentic browser automation features.
- Simular: Simular builds autonomous AI agents that operate computer browsers and applications, and was featured alongside Fellou on Windows 365 for Agents. The two companies share the same browser-automation agent positioning and target similar developer and enterprise audiences.
- Tinyfish: Tinyfish builds AI agents for browser automation and was featured alongside Fellou on Microsoft's Windows 365 for Agents platform. It targets similar agentic workflow use cases but as an earlier-stage emerging player with partial overlap to Fellou's offering.
