Browser coding agent

Beta

A coding agent that works in your browser, on your own files.

An AI workspace where the agent opens a folder on your own drive, then builds and edits real files, all from a browser tab. It also does research with sources, runs a local in-browser model and teaches through a Learning Lab. It is changing fast.

MaiaChat workspace asking 'What do you want to do?', with options to vibe code a project, research with sources or just chat.

Most AI coding tools need a desktop install or a terminal. I wanted an agent that works on real files from a browser tab, with the person still in charge.

02 / How I approached it

The decisions that shaped it.

  1. 01

    The agent works only in the folder the user picks on their own drive.

  2. 02

    Clear modes (Chat, Agent, Loop) and a choice of supervised or full autonomy, so it is obvious what the agent may do.

  3. 03

    A local in-browser model for work that should not leave the machine.

03 / What's inside

What had to work together.

  • Browser agent with project-folder access
  • Chat, Agent and Loop modes
  • Research with sources
  • Local in-browser model, Learning Lab and Comparison Lab
04 / Guardrails

Where the AI stops, and what happens when it is wrong.

  1. 01

    File access limited to the folder the user chooses

  2. 02

    Supervised mode for reviewing changes before they land

  3. 03

    Device access stays off until the user turns it on
