MagenticLite is an experimental agent that works across the browser and local file system

← AI and models
Magentic-UI: browser and file agent. Automates tasks across your browser and local files using small models.

In simple English

This tool lets an artificial intelligence assistant control your web browser and your local files. You can ask it to fill out forms, find prices, or organize documents. It is designed to work with smaller models instead of expensive giant ones. You can stop or approve its actions at any time. It runs inside a sandbox to keep your main system safe.

What it is

An experimental agentic application that coordinates smaller language models to handle browser and file system tasks. It provides a local web interface where you can watch the assistant work and connect your own model endpoints.

What it is good for

Solo builders who want to automate repetitive web research, form filling, or file organization tasks without paying for costly frontier models.
