Reads articles, docs, dashboards, and forms, then answers questions based on the current page content.
Clicks, types, scrolls, navigates, and interacts with pages on your behalf for repetitive or multi-step browser work.
Extracts tables, lists, links, and form data from web pages and can work with PDFs as well.
Works with local llama.cpp setups, OpenAI, Claude, and OpenRouter, so users can choose the model and deployment style they prefer.
Supports local LLM use for reduced data leakage and is described as open-source with no telemetry, tracking, or accounts required.
Uses smart context management to reduce token overflow, starts in read-only Ask Mode by default, and asks before consequential actions.
Open a page in the browser and ask for a summary or a direct answer from the visible content, without copying text into another tool.
Use natural language prompts to pull names, prices, addresses, links, or other structured fields from a page, including PDFs.
Let the agent click through pages, fill forms, scroll, and navigate when a workflow requires multiple browser actions.
Run WebBrain with a local LLM when you want browser assistance without sending page content to a cloud model.
Use profile autofill for saved plaintext details so the agent can move through simple sign-up flows more quickly, while keeping the feature off by default.
