Put it where the problem is.
The advantage a specialist has over a chat tab is context. Install it once and 131 copilots across 20 domains are available on whatever page you are already reading - the contract, the portal, the notice, the posting.
Where it lives
On the page you are already on.
The advantage a specialist has over a chat tab is context. Copilotly runs where the problem is, so you are not copying a contract into a different website and starting your explanation from scratch.
Every browser
Mobile
The extension is on the free plan. Desktop and mobile apps are included with Pro.
Every browser, and what you actually get
Three store listings cover eight browsers. The Chromium ones install the Chrome listing and behave identically - that is not a compromise, it is how Chromium extensions work.

Why no Safari. Safari extensions have to ship as a signed app through the App Store rather than as a web extension, which is a separate build and review process. It is on the list. Until it exists, saying so is better than pointing you at a listing that is not there.
iPhone and Android
Same 131 copilots, same history, laid out for a phone. Conversations sync, so something started on a laptop continues on the phone and back again.
The reason mobile matters more than it sounds: the moment you need a second opinion is rarely the moment you are at a desk. It is a waiting room, a car park, or the ten minutes before a call you are dreading.
Mac and Windows
A desktop app for people who would rather not run it in a browser tab - a global shortcut, document upload, and a window that stays where you put it.

- WindowsWindows 10 and 11
Desktop and mobile apps are included with Pro. The extension and the web app are on the free plan - see what each plan includes.
What the extension actually does
It is not a chat window bolted to your toolbar. The point is that the thing you are confused about is already on screen, and re-typing it into another tab is where the context gets lost.
Permissions, in plain terms
Extension permission prompts are written by the browser and they sound worse than they are. Here is what each one is for.
- “Read and change your data on sites you visit”
- This is the permission that lets it read the text you select and draw its widget on the page. It is the broadest-sounding one Chrome offers and there is no narrower version that would still work. What it does not do is read pages you have not asked it about, or send page content anywhere in the background.
- Storage
- Keeps your settings and your signed-in session so you do not log in on every page. Local to your browser.
- Per-site control
- You can switch it off for any site, and most people switch it off for banking and email. That setting is yours and it persists.
Conversations are encrypted in transit and at rest, are never used to train models, and are deletable at any time. The detail is in the privacy policy, and how we work generally is in editorial standards.
If it does not appear
- Check it is pinned. Chrome and Edge hide new extensions behind the puzzle-piece icon by default. Open that menu and pin Copilotly - this is the cause roughly nine times out of ten.
- Reload the tab. A page that was already open when you installed does not have the extension running on it. Reload, or open a new tab.
- Check the site is not disabled. If you turned it off for a site earlier, it stays off. Re-enable it from the extension menu.
- Check for a restricted page. Browsers block extensions on their own internal pages - the new tab page, settings, and the extension store itself. That is a browser rule and not something an extension can override.
- Still nothing? Tell us which browser and version, and what you see. That is usually enough to identify it.
Install questions
Which browsers is the extension available on?
Chrome, Edge and Firefox have their own store listings. Brave, Opera, Arc and Vivaldi are Chromium-based, so they install the Chrome listing and work identically - you are not getting a lesser version.
There is no Safari build yet. Safari extensions need a signed App Store build, which is a different pipeline, and saying so beats sending you to a dead listing.
What does the extension actually do on a page?
It adds a widget you can call up anywhere. Select text - a lease clause, a lab value, a paragraph of an offer letter - and hand it straight to the relevant copilot without leaving the page or re-explaining the context.
Context is the whole advantage a specialist has over a chat tab, and re-typing the situation is where most of it gets lost. You can disable it per site.
Do I need a paid plan to use the extension?
No. The extension is on the free plan, along with three copilots of your choice and 50 messages a day. No card, and the free plan is a plan rather than a trial.
Pro adds all 131 copilots, unlimited messages, and the desktop and mobile apps. See what each plan includes.
Is the mobile app the same as the web app?
Same 131 copilots and the same conversation history, laid out for a phone. Anything you start on a laptop continues on the phone and back.
The reason it matters is timing: the moment you need a second opinion is rarely the moment you are at a desk. It is usually in a waiting room, a car park, or the ten minutes before a call.
What permissions does the extension ask for?
Access to page content, so it can read the text you select, and storage, so it can keep your settings and session. That is it.
It does not read pages you have not asked it to, and per-site controls let you switch it off anywhere you would rather it not run - which for most people means their bank and their email.
Is my data used to train models?
No. Conversations are encrypted in transit and at rest, are not used to train models, and are not shared. You can delete any conversation, or your whole account, at any point.
The full detail is in the privacy policy, which is written to be read rather than to be complied with.
Will it slow my browser down?
It is idle until you call it. There is no background scraping, no content script doing work on every page load, and no analytics beacon firing as you browse.
If you do notice a slowdown on a specific site, turn it off for that site rather than uninstalling - the per-site toggle exists for exactly that.
How do I uninstall it?
Right-click the icon in your browser toolbar and choose remove, or manage it from your browser's extensions page. Nothing is left behind locally.
Your account and history are separate from the extension - removing one does not touch the other. To delete the account itself, do that from account settings or ask us.
