In their own words
Auto Browser
Auto Browser is a free Chrome extension that uses an AI agent in the browser’s side panel. It reads a webpage’s accessibility tree and can click, type, scroll, navigate, fill forms, and handle research tasks described in plain English. Pages exposing WebMCP tools can let it use those tools instead of the page DOM. Supported providers include Chrome Built-in AI (Gemini Nano), Google Gemini, OpenRouter, and local OpenAI-compatible endpoints such as Ollama and LM Studio. You can change providers during a conversation without losing its history. Write actions require approval, arbitrary JavaScript prompts for approval, and banking, government, and healthcare origins are blocked by default. The extension is free to install at free; Google Gemini and OpenRouter charge per request using your API key. Chrome 126 or newer is required for basic use. Attachments can be images or audio up to 10 MB each.
Fellou
Fellou is an agentic AI browser for automating web and desktop work on macOS. Users describe a task in natural language, then can review, edit, or approve the step-by-step workflow before it runs. Its research tools work across the internet, including logged-in accounts such as Reddit, and create reports with verifiable sources. Browser Use can scrape data and fill forms; with permission, Computer Use can operate local apps and manage files. Workflows can connect apps, with LinkedIn-to-Notion data transfer given as an example, and can be scheduled once or on a recurring basis. Users can monitor progress and intervene during execution. Developers can use the open-source Eko 2.0 framework to build custom agents with natural language and JavaScript. A free plan is listed, alongside paid options including Plus at $19 a month and Pro at $39.90 a month. Fellou says Spark use varies significantly with workflow complexity, so task estimates are approximate. Its privacy policy says service content and output may be used to improve services after encryption and de-identification; users can object to data use for service training.
