Fellou
An agentic browser that automates multi-step web research and workflows from a single prompt
Best for
1|Fellou is an agentic browser that automates complex, multi-step web tasks through natural language prompts. Launched in 2026, it plans before executing, turning plain English instructions into reliable workflows across websites and connected apps. 2| 3|- Deep Action mode -- Fellou plans the entire workflow as a step-by-step sequence and shows it to you for approval before executing. This plan-first architecture reduces errors and gives you full visibility into what the AI will do on your behalf. 4| 5|- Shadow Workspace -- Background task processing that runs your automations while you continue browsing normally. Research reports, data extraction, and cross-app workflows complete in a separate workspace without blocking your main browser session. 6| 7|- Cross-app integrations -- Connects directly to Notion, Google, Reddit, X (Twitter), and general web platforms. Fellou operates across sites where you are logged in, pulling data from multiple sources in a single workflow without manual copy-paste. 8| 9|- Natural language task execution -- Describe what you need in plain English and Fellou builds the automation. No coding, no Zapier-style connector setup. Travel planning, competitive research, and report compilation all start with a single prompt. 10| 11|- MCP support -- MCP integration lets Fellou connect with other AI tools and services that support the Model Context Protocol standard, expanding its automation capabilities beyond built-in integrations. 12| 13|- Free tier Sparks deplete fast -- This is a major Limitation. 1000 Sparks sound generous, but complex multi-step workflows consume Sparks quickly. A single deep research task across 10+ sources can burn through a significant portion of the monthly free allowance. 14| 15|- No API for custom integrations -- Another Limitation is that Fellou does not offer a public API, so you cannot build custom integrations or connect Fellou to external automation tools like Zapier or n8n programmatically. 16| 17|- macOS and web only -- A final Limitation is that there is no Windows desktop app and no mobile apps as of 2026. Users on Windows must rely on the web version, which may have reduced performance for background Shadow Workspace tasks.
Limitations: - Cost: Starts at $19.9/mo with unpredictable usage limits. - API: No API available for integration. - Steep Learning Curve: Not as simple as basic chatbots.
Pricing: - Free Tier: Basic allowance included. - Paid Plan: Starts at $19.9/mo.
Our Verdict
1|Fellou is a promising agentic browser that fills a real gap between passive AI chat tools and full automation platforms. It scores 7.8/10. Its Deep Action planning mode and Shadow Workspace background processing make it genuinely useful for research-heavy workflows. The Sparks-based pricing can be hard to predict, and the lack of an API limits extensibility for advanced users. 2| 3|
For the Vibe Builder, Fellou offers cross-app workflow automation without writing code or configuring integration platforms. Deep Action mode lets you review the plan before execution, and Shadow Workspace keeps tasks running in the background. The main trade-off is the absence of a public API, which means you cannot extend Fellou or connect it to external automation tools. 4| 5|For the Basic User, Fellou eliminates the tedious grunt work of opening dozens of tabs, copying data, and compiling research by hand. Describe what you need in one prompt and Fellou handles the rest. The free tier with 1000 Sparks is enough to test the core experience, though active users will hit the limit quickly. 6| 7|Skip it if you need a Windows or mobile app, require API access for custom integrations, or want predictable flat-rate pricing instead of a Sparks consumption model. Consider using Lindy or Relevance AI for more flexible agent building with broader platform support.
