Meet WebBrain: An Open-Source, Local-First AI Browser Agent That Reads Pages and Automates Tasks in Chrome and Firefox
WebBrain is a free, open-source browser agent for Chrome and Firefox. It reads pages, extracts data, and automates multi-step tasks. Unlike most browser AI plugins, it can also run entirely on a local model. It is built by Emre Sokullu and licensed under MIT. The full source lives on GitHub. Run the agent against a local model, and no page data leaves your machine. Connect a cloud API when you want more capability. What is WebBrain? WebBrain lives in your browser’s side panel

WebBrain is a free, open-source browser extension for Chrome and Firefox that uses AI to read web pages, extract data, and automate tasks. It can run entirely on a local model installed on a user's machine, meaning page data never leaves the device, or it can connect to cloud APIs for more capability. The tool operates in two modes: Ask mode for reading pages without making changes, and Act mode for clicking, typing, and automating multi-step workflows. Security is built in by design, starting in read-only mode and requiring approval before the agent takes consequential actions like submitting forms or making purchases.

RAG-Anything Tutorial: Build a Multimodal Retrieval Pipeline for Text, Tables, Equations, and Images in Colab
In this tutorial, we build a RAG-Anything workflow and use it to explore how multimodal retrieval works across text, tables, equations, and images. We start by preparing the Colab environment, installing the required packages, and securely entering our OpenAI API key at runtime to keep the notebook practical and safe to run. We then create a synthetic multimodal report, generate a chart and PDF, convert the content into RAG-Anything’s direct content_list format, and insert it into the retrieval
