parallax
Alpha macOS 11 or later

Work through a repository with the ChatGPT account you already have open.

Parallax is a macOS workspace that holds projects, threads, tool activity, and approvals in one window. A Chrome extension you load yourself drives your signed-in ChatGPT tab, so there is no API key to paste and no second account to create.

Checking the latest release

How a message reaches the model

  1. Your repository A folder you open from the app
  2. Parallax Threads, tool activity, approvals
  3. Chrome bridge An extension you load yourself
  4. chatgpt.com The tab you are already signed in to
The first three steps run on your Mac. Only the last one is a network session, and it is the one you are already signed in to. Parallax stores no model credentials of its own.

One workspace instead of a browser tab and a terminal

Work stays grouped the way the repository is already grouped, and anything that needs a decision arrives where you are reading.

Projects

Threads belong to a repository

Each project keeps its own folder, history, active state, and unread status instead of scrolling into one shared feed.

Tool activity

Commands read as work, not noise

Related commands collect beneath one activity label, and raw output stays one click away instead of filling the transcript.

Approvals

Review without leaving the thread

An action that changes the workspace turns the composer into a review surface, so approving does not mean switching context.

What you download

Both pieces ship from the same tagged release. This page resolves the rows below against the newest GitHub Release, so they describe the build you will actually get.

Downloads in the latest Parallax release, with format, size, and requirement.
Component Format Size Requirement
Parallax for macOS Universal .dmg Resolving macOS 11 or later, Apple silicon or Intel
Chrome bridge Unpacked .zip Resolving Chrome with developer mode enabled

The macOS build is signed, notarized, and universal. Sizes come from the release assets when the page loads.

Install once, then let it update

Three steps, and then Parallax checks for new releases in the background. A downloaded update installs on the next restart, and its status stays visible in Settings.

Step 1

Move Parallax into Applications

Open the DMG and drag the app across.

Step 2

Load the Chrome bridge

Unpack the ZIP, open chrome://extensions, turn on developer mode, and load the unpacked folder.

Step 3

Open a repository

Sign in to ChatGPT in that Chrome profile, pick a folder in Parallax, and start a thread.

Start with the repository you have open right now

The download is the whole evaluation. Install it, point it at a folder, and see whether the workspace holds up on real work.

Alpha. The workspace, the bridge protocol, and the release layout can still change between versions.
