Free, open-source browser AI agent for Chrome, Firefox, and Edge that reads pages, extracts data, and automates tasks with any LLM.
WebBrain is an MIT-licensed browser extension that puts a full AI agent in your sidebar for Chrome, Firefox, and Edge, giving you a self-hostable alternative to proprietary browser AI plugins. In Ask Mode it reads the current page — articles, docs, dashboards, PDFs, forms — and answers questions grounded in that content. In Act Mode it clicks, types, scrolls, navigates, and interacts on your behalf, always asking before consequential actions and defending against hidden prompt injections. It works with any provider you plug in — local llama.cpp for offline privacy, or OpenAI, Anthropic Claude, and OpenRouter for hosted models — and can pair a fast text-only model for planning with a separate vision model for reading screenshots to keep costs down. Smart context management prevents token overflow, no telemetry or accounts are required, and the UI ships in 20+ languages so it works globally out of the box.
WebBrain is a free, open-source browser AI agent compatible with Chrome, Firefox, and Edge. It reads web pages, extracts data, and automates tasks using any large language model (LLM), significantly enhancing productivity and efficiency while browsing the internet.
WebBrain leverages advanced AI technology to enhance your web browsing experience. It functions as an AI agent that can comprehend and interpret the content of web pages. With its ability to extract relevant data, WebBrain streamlines information-gathering processes, making it ideal for researchers, students, and professionals alike.
WebBrain operates by combining advanced page understanding, a full browser agent for automation, and a multi-provider large language model. It reads content, interacts with web pages, and offers offline capabilities, ensuring efficient task execution while prioritizing user safety and privacy.
WebBrain harnesses sophisticated AI technology to enhance web interactions. Here’s how it works:
Page Understanding: WebBrain can read and comprehend a wide range of content, including web pages, PDFs, articles, and documents. By analyzing the text, it can answer specific questions or summarize information effectively. For instance, if you open a lengthy research article, you can ask WebBrain to provide a concise summary or to clarify complex sections.
Full Browser Agent: This feature allows WebBrain to automate repetitive tasks by performing actions such as clicking, typing, scrolling, and navigating through pages. Users can issue natural language instructions like “Fill out the tax form” or “Search for the best laptop,” and WebBrain executes these commands seamlessly, saving time and effort.
Read-Only Ask Mode: To enhance security, WebBrain operates in a “Read-Only Ask Mode” by default. This means it will ask for user confirmation before taking any significant actions, particularly on sensitive fields, thereby protecting against potential hijacking or unauthorized changes.
Multi-Provider LLM Compatibility: WebBrain is compatible with various large language models, including local llama.cpp, OpenAI, Anthropic Claude, and OpenRouter. This flexibility allows users to choose their preferred model or operate fully offline, which is particularly beneficial for those handling sensitive data.
Dedicated Vision Model: By utilizing a separate vision-capable model for processing screenshots, WebBrain can deliver faster and more cost-effective operations than a singular multimodal model. This functionality is particularly useful for extracting visual data from web pages.
Use Cases:
WebBrain offers advanced features like Page Understanding, a Full Browser Agent for task automation, and a Read-Only Ask Mode to enhance user safety. It supports multiple language models and incorporates a dedicated vision model, making it versatile for different web interactions and automation needs.
WebBrain is designed to streamline web interactions and automate repetitive tasks efficiently. Here’s a breakdown of its main features:
Page Understanding: WebBrain can read and understand various formats, including web pages, PDFs, articles, documents, and dashboards. This capability allows users to ask questions about the content displayed on their screen, yielding immediate answers based on real-time data.
Full Browser Agent: This feature mimics user behavior by clicking, typing, scrolling, and navigating. Users can provide natural language instructions to automate tasks such as filling out forms or gathering information, significantly reducing time spent on mundane activities.
Read-Only Ask Mode: For enhanced security, WebBrain operates in a Read-Only Ask Mode by default. This means it will prompt the user for confirmation before performing any significant actions, especially in sensitive areas, effectively defending against potential hijacking or unintended consequences.
Multi-Provider LLM: WebBrain supports various language models, including local llama.cpp, OpenAI, Anthropic Claude, and OpenRouter. This feature allows users to choose a model based on their needs, ensuring flexibility and performance. Additionally, it can run completely offline, catering to privacy-conscious users.
Dedicated Vision Model: By combining a fast text-only planning model with a vision-capable model, WebBrain can process screenshots and images more efficiently. This dual approach is not only cheaper but also faster than using a single multimodal model, ensuring quicker responses and interactions.
