WebBrain est une extension de navigateur gratuite et open source qui apporte des capacités d’agent IA à Chrome, Firefox et Edge. Elle lit les pages, extrait des données et automatise les tâches du navigateur avec le fournisseur de LLM de votre choix, y compris des modèles locaux.

Qu'est-ce que WebBrain ?

WebBrain is a browser extension that adds AI agent features to your browser sidebar. It can understand pages, answer questions from the current content, extract structured data, and automate tasks such as clicking, typing, scrolling, and navigating.

The product is designed as a free, open-source alternative to proprietary browser AI tools. It supports Chrome, Firefox, and Edge, and the docs say it works with multiple LLM providers, including local models that can run entirely on your machine.

Que peut faire WebBrain ?

Page understanding

Reads articles, docs, dashboards, and forms, then answers questions based on the current page content.

Browser action agent

Clicks, types, scrolls, navigates, and interacts with pages on your behalf for repetitive or multi-step browser work.

Structured data extraction

Extracts tables, lists, links, and form data from web pages and can work with PDFs as well.

Multi-provider LLM support

Works with local llama.cpp setups, OpenAI, Claude, and OpenRouter, so users can choose the model and deployment style they prefer.

Privacy-first operation

Supports local LLM use for reduced data leakage and is described as open-source with no telemetry, tracking, or accounts required.

Context and safety controls

Uses smart context management to reduce token overflow, starts in read-only Ask Mode by default, and asks before consequential actions.

Cas d'utilisation

“Summarize a page or article”

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.

“Extract data from tables and forms”

Use natural language prompts to pull names, prices, addresses, links, or other structured fields from a page, including PDFs.

“Automate routine browsing steps”

Let the agent click through pages, fill forms, scroll, and navigate when a workflow requires multiple browser actions.

“Use local models for private workflows”

Run WebBrain with a local LLM when you want browser assistance without sending page content to a cloud model.

“Handle repetitive low-stakes form entry”

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.

Does WebBrain support local or offline use?

Yes. The site says you can run it with a local model, and the docs describe local LLM use as a privacy-oriented option that can keep data on your machine. It does not claim fully offline use for every feature in every setup, so availability depends on the model and configuration.
