Atlarix for Chrome
An agent in the browser you are already signed into
Open the side panel, ask for something, and Atlarix works on the page in front of it — with the sessions you are already logged into, without asking you to copy anything into a chat window.
It is also how the Atlarix desktop app tests what it builds: the desktop agent opens your dev server in your Chrome and drives it from there. That part is free on every plan; only the side-panel agent needs a balance, from $10 of credit.

What you can do with it
It is the same agent as the desktop app, working on web pages instead of a repository.
Reads the page you are on
Ask about what is in front of you, or about a tab you have not opened yet. It follows links and works across several tabs at once — comparing, cross-referencing, collecting.
Fills forms, and stops before sending
Anything that sends, buys, posts or deletes stops and asks you first. Filling is automatic; submitting never is.
Reads whole documents
Attach a spreadsheet or a PDF and ask about it. It reads the entire file rather than the first page of it. Paste a long block of text and it becomes an attachment instead of filling the composer.
Builds things you can keep
Ask for a relic — a self-contained chart, table or calculator that opens in its own tab — or ask for the answer as a file, and it writes one you can download.
Follows you between devices
Conversations belong to your account, so you can pick one up on another machine. Page content is not part of what syncs.
Groups every tab it opens
Tabs Atlarix opens are collected into one labelled group, so you can see at a glance what it has touched. Closing the group stops it.
What it asks for, and what that means
When you install it, Chrome will say “Read and change all your data on all websites”. That is the real prompt and we would rather you read it here first than be surprised by it. Host access is a required permission, because the desktop app drives the browser and a request you already approved in the app should not ask you a second time in Chrome.
The in-panel agent holds itself to a narrower limit than Chrome grants it: it asks the first time it touches a site, and every site it has worked on is listed on your account page and revocable there.
How to actually take the access back
Revoking a site on your account page constrains the side panel. It does not withdraw host access from the desktop integration, because Chrome does not let an extension give back a permission it requires. To narrow or remove that, open chrome://extensions, find Atlarix, and set Site access to the sites you want — or switch it off. That is the control that actually governs both paths.
What happens to your data
To answer you, the text of the pages Atlarix reads — and screenshots of its own tabs — go to the model, along with the parts of your files a question needs, and nowhere else. The files themselves stay on your device. What syncs to your account is what was said — your messages and its replies — so a conversation can continue somewhere else; page content is not stored on our servers. The extension runs only on paid Atlarix Core, so nothing it handles is used for training.
What it costs
The extension is free to install, and the desktop app drives your Chrome through it on every plan, including Free. Its own side-panel agent runs on Atlarix Auto, which picks the right Atlarix Core model for each step, and that runs on your Atlarix balance: add pay-as-you-go credit from $10 and pay only for what you use, with no subscription, or get Atlarix Pro — $19/month, which includes Core usage across the desktop app, this extension and Atlarix Reviewer. It is one account and one balance across all three surfaces. You always see what a conversation is using in the panel, and Atlarix will not start a turn it cannot pay for. (Free Atlarix Auto is a desktop-app option; the side-panel agent does not use it.)

What does the Atlarix Chrome extension do?
It puts the Atlarix agent in the browser you are already signed into. Open the side panel and ask; it reads pages, follows links and fills forms, and never submits one without asking. It is also how the Atlarix desktop app opens your dev server in your Chrome and tests what it builds.
Is the Atlarix Chrome extension free?
It is free to install, and the desktop app drives your Chrome through it on every plan, including Free. The extension's own side-panel agent runs on Atlarix Auto from your Atlarix balance: add pay-as-you-go credit from $10, with no subscription, or use the usage included with Atlarix Pro. It is one account and one balance across the desktop app, the extension and Atlarix Reviewer.
Why does it ask to read and change data on all websites?
Host access is required because the desktop app drives the browser, and a request you already approved in the app should not ask a second time in Chrome. The in-panel agent asks the first time it touches a site, and you can narrow access any time in chrome://extensions under Site access.
What happens to the pages it reads?
The text of the pages it reads, and screenshots of its own tabs, go to the model to answer you and nowhere else. Page content is not stored on Atlarix servers, and the extension runs only on paid Atlarix Core, so nothing it handles is used for training.
