Turn Notion, Gmail and ChatGPT into Desktop Apps with WebCatalog

Your Notion workspace, your inbox and your AI assistant are probably the three tabs you open most every day. They are also the three tabs most likely to vanish into a row of forty others. Giving each one its own window and icon is a small change that makes a busy workday feel a lot calmer.

WebCatalog is a desktop tool that turns websites into WebCatalog desktop apps, so Notion, Gmail and ChatGPT can each live in their own window with their own Dock or taskbar icon. In this guide we walk through how to install WebCatalog, add those three apps from its catalog, run more than one account side by side, and organise everything into Spaces. We also cover what is free, what needs a paid plan, and when the official Notion and ChatGPT desktop apps might be the better choice.

What WebCatalog is (and what it is not)

WebCatalog describes itself as a way to turn websites into desktop apps, manage multiple accounts and organise them into spaces. Its “Turn websites into desktop apps” page explains that each app is a site-specific browser with its own window, icon, cookies, sessions and extensions. In practice, that means Gmail stops being one tab among many and becomes something you can launch, pin and switch to like any other program.

It is important to be clear about what is happening under the hood. WebCatalog’s own documentation says desktop apps “load the original website,” so you get the same content and features you would see in a browser. You are not getting a different version of Notion or ChatGPT. You are getting the same web app, in a cleaner container.

Each catalog listing also carries a disclaimer. The Notion, Gmail and ChatGPT pages on webcatalog.io all state that WebCatalog “is not affiliated, associated, authorized, endorsed by or in any way officially connected to” the service in question. So these are not official apps from Notion, Google or OpenAI. They are WebCatalog wrappers around the official websites.

The main features, according to WebCatalog

Here is what webcatalog.io lists across its homepage, desktop page and solution pages. We have stuck to what the site itself says.

• Dedicated desktop apps: each website gets its own window, icon and place in your Dock or taskbar, with native notifications and badges.
• Multiple accounts (profiles): sign in to several accounts of the same app, each with its own separate session, and switch without logging out.
• Spaces: group apps and accounts by context (work, personal, clients, projects) and switch between them without closing anything. Spaces can also contain subspaces.
• Per-app extensions: add an extension to one app without affecting the others.
• Ad and tracker blocking: built in and turned on in app settings.
• App lock: set a password and an auto-lock delay for when you switch away.
• Home and widgets: a customisable home with widgets such as weather, to-dos, a focus timer, world clock and currency conversion.
• Cloud sync: sign in to your WebCatalog account to sync your setup across devices.
• A large catalog: the homepage cites “65,000+ apps ready to install,” and you can also add any website yourself.

One honest caveat from WebCatalog itself: its privacy controls separate app data from your browser, but the site notes they “don’t make you anonymous online.” Treat it as an organisation tool, not a privacy product.

Why turn Notion, Gmail and ChatGPT into WebCatalog desktop apps?

If you run a small business, a freelance practice or a side project, these three tools often form the backbone of the day. Notion holds your plans, client notes and SOPs. Gmail is where work arrives. ChatGPT is where you draft, summarise and brainstorm. Keeping all three as browser tabs means they compete with research tabs, social media and everything else.

Giving them their own windows has a few practical benefits that line up with what WebCatalog promotes:

• Faster switching: use your normal app switcher (Cmd+Tab on Mac, Alt+Tab on Windows) to jump straight to your inbox instead of hunting through tabs.
• Notifications and badges: WebCatalog says apps support native notifications and unread counts, so a Gmail badge on your Dock icon can replace a tab you keep checking.
• Separate sign-ins: cookies and logins stay apart from your everyday browser, which helps when your personal browser is signed into a different Google account.
• Several accounts at once: keep a business Gmail and a personal Gmail open side by side, or two ChatGPT accounts for different clients.
• Less browser clutter: closing your browser no longer closes your core work tools.

Before you start: Notion and ChatGPT already have official desktop apps

We want to be upfront here, because it changes whether WebCatalog is right for you. Notion offers its own official desktop app for macOS and Windows on its download page. OpenAI also offers an official ChatGPT desktop app, and its download page lists macOS and Windows (the macOS version requires macOS 14 or later on Apple Silicon, according to OpenAI). Neither download page mentions Linux.

Gmail is different. Gmail is primarily used in the browser, and Google does not offer a separate Gmail download for Mac or Windows in the way Notion does. That makes Gmail the most natural fit for a WebCatalog desktop app out of the three.

When the official apps are the better choice

• You only use one Notion account and one ChatGPT account.
• You want features that the official desktop apps add on top of the website. Check Notion’s and OpenAI’s own pages for what those are.
• You prefer software published directly by the company that makes the service.

When WebCatalog still makes sense

• You use Linux. WebCatalog lists Linux support, while the official Notion and ChatGPT download pages list only macOS and Windows.
• You juggle multiple accounts. Profiles let you keep, for example, a client’s Notion workspace login separate from your own, each in its own session.
• You want one consistent system. Instead of three different apps with three different behaviours, everything lives in WebCatalog with the same profile and Spaces model.
• You want to group tools by client or project. Spaces let you put a client’s Gmail, Notion and ChatGPT profiles together and switch the whole set at once.
• You also want Gmail as an app. Since Gmail has no standalone desktop download from Google, WebCatalog fills that gap, and adding Notion and ChatGPT keeps things consistent.

A mixed setup is also perfectly reasonable: use the official Notion app, and use WebCatalog for Gmail plus a second ChatGPT account. That kind of setup also fits within the free plan’s two-app limit.

How to set up WebCatalog desktop apps for Notion, Gmail and ChatGPT

The steps below follow WebCatalog’s “Get started with the WebCatalog desktop app” guide, its “Create and manage profiles” article and its solution pages. Where the docs do not name a specific button or menu, we describe the step in general terms rather than guess at labels, since the interface can change between versions.

Step 1: Download and install WebCatalog

Start from the WebCatalog website. The desktop page offers a “Download for macOS” button and has separate download pages for Windows and Linux.

1. Go to WebCatalog and open the desktop download section.
2. Choose the download for your operating system (macOS, Windows or Linux).
3. Run the installer as you would for any other desktop program.
4. Open WebCatalog once installation finishes.

Step 2: Sign in to your WebCatalog account

WebCatalog’s getting-started guide recommends signing in to a WebCatalog account so your setup syncs across devices. The pricing page lists cloud sync as included on the free Basic plan, and it notes that no credit card is required to start.

1. Create a WebCatalog account or sign in to an existing one from the desktop app.
2. Stay on the free plan for now. You can start a Pro trial later if you need more than two apps.

Step 3: Find and install the Notion app

WebCatalog’s catalog includes a Notion listing, which describes Notion as “a workspace app for notes, databases, tasks, calendars, and collaboration.” WebCatalog’s desktop apps page describes the install flow simply: find the app by searching the catalog or pasting a site’s URL, install it in one click, and it appears in your Dock, Start menu or app launcher.

1. In WebCatalog, search the catalog for “Notion”.
2. Select the Notion listing and install it.
3. Open the new Notion app. It loads the normal Notion website in its own window.
4. Sign in with your Notion account. If you do not have one yet, you can sign up for Notion here.
5. Pin the app to your Dock or taskbar so it is always one click away.

Step 4: Install the Gmail app

The Gmail listing on webcatalog.io says you can launch Gmail from your Dock or taskbar, use it in a window separate from browser tabs, and switch between multiple Gmail accounts without logging out. This is the app most people get the most value from, since there is no separate Gmail download from Google.

1. Search the catalog for “Gmail” and install the listing.
2. Open the Gmail app and sign in to your main Google account.
3. Allow notifications when your operating system asks, so new mail can trigger native alerts and badges.
4. Pin it next to your Notion app.

Step 5: Install the ChatGPT app (or decide to upgrade)

The ChatGPT listing on webcatalog.io promotes launching ChatGPT from your Dock or taskbar and managing multiple ChatGPT accounts without logging out. Here is where the free plan’s limit matters: Basic allows 2 desktop apps, so a third app needs Pro.

1. Decide whether you need all three apps in WebCatalog. If you already use the official ChatGPT or Notion desktop app, you may only need two.
2. If you want all three, start the 7-day Pro trial from the pricing page.
3. Search the catalog for “ChatGPT” and install it.
4. Open the app and sign in to your OpenAI account.

Step 6: Add a second account with profiles

Profiles are how WebCatalog handles multiple accounts. Its multiple account page explains that “a profile keeps an app’s session and browsing data separate, so you can use multiple accounts without logging out.” The “Create and manage profiles” help article gives these steps:

1. Launch WebCatalog Desktop.
2. Click “Profiles”.
3. Click “Add profile”.
4. Enter a name for the profile (for example “Client A” or “Personal”) and customise it if you want.
5. Open an app using that profile, then sign in to the account you want to use.

The same article notes that one profile can be used with several desktop apps, which helps when those apps share an account or login session. That is handy for Google: a single “Business” profile signed into your work Google account can serve Gmail and any other Google app you add later.

You can rename, customise or delete profiles from the same “Profiles” area. WebCatalog’s help article explains that deleting a profile removes its local browsing data and signed-in sessions from WebCatalog, but it does not delete your accounts with the websites themselves.

Keep the plan limit in mind here too. The free Basic plan includes 2 profiles, while Pro includes unlimited profiles.

Step 7: Organise your apps with Spaces

Spaces are WebCatalog’s way of grouping apps and accounts by context. According to its help center, “Spaces help you organize your apps, accounts, and bookmarks in the WebCatalog desktop app,” and spaces can contain subspaces. The Spaces page lays out a three-part flow:

1. Create a space and name it after a client, project or part of your life.
2. Add apps and accounts: install the apps you need and sign in.
3. Switch and go: open a space when you need it and close it when you are finished. WebCatalog says a space opens in its own window.

A simple structure for a small business owner might look like this:

• Business: Gmail (work profile), Notion (company workspace), ChatGPT (work account).
• Client projects: subspaces per client, each with that client’s Notion or Gmail login in its own profile.
• Personal: personal Gmail and your own Notion life planner.

Note that the free plan includes only 1 space. Multiple spaces, like the structure above, need Pro, which includes unlimited spaces. Teams on the Business plan can also use shared spaces, where admins set up apps once and everyone receives the same space. WebCatalog says logins, bookmarks, settings and browsing data stay private on each computer, and “Not even admins can see them.”

Step 8: Fine-tune each app

Once the basics are in place, a few of WebCatalog’s listed features are worth a look. Exact setting names may vary, so check the app itself:

1. Check that notifications are on for Gmail and off (or limited) for apps you do not want interrupting you.
2. Turn on ad and tracker blocking in app settings if you want it. WebCatalog’s comparison table lists the ad blocker as part of the free plan.
3. Consider app lock for Gmail if you share a computer. WebCatalog describes it as a password plus an auto-lock delay.
4. Add extensions only to the apps that need them. WebCatalog says an extension added to one app does not affect the others.

WebCatalog pricing (Pricing as of October 2026)

WebCatalog’s help center says “The core features of WebCatalog Desktop are 100% free,” with paid plans unlocking premium features. Here is what the official pricing page shows. Prices are listed with a “$” symbol and “plus local taxes,” and annual billing is shown; the page says you can “Save up to 20% with yearly” but does not display a separate monthly-billed price, so check the pricing page for current monthly rates.

Plan	Price (billed annually)	Key limits and features
Basic	Free, no credit card required	2 desktop apps, 2 profiles, 1 space, cloud sync, ad blocker, basic widgets and customisation, focus mode
Pro	$5 per month, plus local taxes, 7-day free trial	Unlimited desktop apps, profiles and spaces, all widgets and customisation, Pomodoro timer, weather forecasts, priority support
Business	$8 per user per month, plus local taxes, 7-day free trial	Everything in Pro plus shared spaces, team management, centralised billing and SAML SSO

For the Notion, Gmail and ChatGPT setup in this guide, the maths is simple. Two of the three fit on the free plan. All three, or more than two accounts, or more than one space, puts you on Pro. The pricing page also notes the desktop app items are “Only available on WebCatalog for macOS, Windows, and Linux.”

WebCatalog pros and cons

Pros

• Works across macOS, Windows and Linux, which matters for Linux users who cannot install the official Notion or ChatGPT apps.
• Profiles make running several accounts of the same service much tidier than juggling browser profiles.
• Spaces and subspaces give a clear structure for client work.
• A large catalog, plus the option to add any website yourself.
• A usable free plan with cloud sync and an ad blocker, and an affordable Pro tier.
• Built-in extras such as app lock and per-app extensions.

Cons

• The free plan’s 2-app limit is one short of the full Notion, Gmail and ChatGPT trio.
• Apps are not official. Each listing states WebCatalog is not affiliated with the service.
• Features match the website, so you will not get extras that an official desktop app might add.
• WebCatalog’s own docs note that DRM-protected videos do not play in the desktop app, which is worth knowing if you add streaming sites later.
• The pricing page shows annual pricing; monthly rates are not displayed as clearly.

Who WebCatalog is for (and who should skip it)

A good fit if you are

• A freelancer or agency owner logged in to several client Notion workspaces and Gmail accounts.
• A Linux user who wants Notion or ChatGPT in its own window.
• Someone who wants Gmail as a proper desktop app with badges and notifications.
• A small team that wants the same set of apps on everyone’s computer through shared spaces (Business plan).

Probably not for you if

• You use one account per service and are happy with the official Notion and ChatGPT desktop apps.
• You already use your browser’s own “install as app” feature and do not need multiple accounts.
• You only want official software from each vendor.

Keep your workspace organised in Notion

A dedicated Notion window is only as useful as the workspace inside it. If your Notion is still a pile of loose pages, now is a good time to give it some structure, so that the app you pinned to your Dock opens straight to something useful.

• Free Notion Starter Kit: a free set of Create Digital Tools templates to get a clean, organised workspace going without building from scratch.
• 2027 Life Planner: plan goals, habits and the year ahead in one place. It pairs nicely with a “Personal” space in WebCatalog that keeps your planner apart from client work.

Both templates run in any Notion account. If you are new to Notion, you can create a free Notion account first, then duplicate the templates into your workspace and open them from your new desktop app.

Tips for a calmer WebCatalog setup

• Name profiles clearly. WebCatalog’s profile page suggests giving each account a name, then clicking the one you want. “Business Gmail” and “Personal Gmail” beat “Profile 1” and “Profile 2”.
• Start small. Use the free plan with Gmail and one other app for a week before deciding whether you need Pro.
• Match spaces to how you actually work. If you do not have clients, a simple Work and Personal split may be all you need.
• Keep notifications intentional. One badge on Gmail is useful; badges everywhere become noise.
• Use the official app where it is clearly better. There is no rule that everything must live in WebCatalog.

FAQ

Is WebCatalog free?

Yes, there is a free Basic plan. WebCatalog’s help center says the core features of WebCatalog Desktop are free, and the pricing page lists 2 desktop apps, 2 profiles and 1 space on Basic, with no credit card required. Pro ($5 per month billed annually, plus local taxes, as of October 2026) removes those limits.

Does WebCatalog work on Mac, Windows and Linux?

According to webcatalog.io, the desktop app is available for macOS, Windows and Linux, and each platform has its own download page. The pricing page also states that desktop app features are only available on WebCatalog for those three operating systems.

Are the Notion, Gmail and ChatGPT apps in WebCatalog official?

No. Each catalog listing states that WebCatalog is not affiliated, associated, authorized or endorsed by the service. WebCatalog’s documentation explains that its desktop apps load the original website, so you are using the real Notion, Gmail or ChatGPT site inside a separate window.

Should I use WebCatalog or the official Notion and ChatGPT desktop apps?

If you use one account each on macOS or Windows, the official apps are a sensible default. WebCatalog makes more sense if you are on Linux, need several accounts of the same service, want to group tools by client with Spaces, or want Gmail as a desktop app too.

Can I use two Gmail accounts at the same time in WebCatalog?

Yes, that is what profiles are for. WebCatalog says each profile keeps an app’s session and browsing data separate, so you can use multiple accounts without logging out. Note that the free plan includes 2 profiles; Pro includes unlimited profiles.

What happens to my accounts if I delete a profile?

WebCatalog’s help article says deleting a profile removes its local browsing data and signed-in sessions from WebCatalog. Your actual accounts with Gmail, Notion or ChatGPT are not deleted.

Can I add a website that is not in the catalog?

Yes. WebCatalog says you can install from its catalog or add any website by pasting its URL. Keep the free plan’s limit of 2 desktop apps in mind when you add your own.

Conclusion

WebCatalog is a straightforward way to pull Notion, Gmail and ChatGPT out of your browser and give each one its own window, icon and notifications. The free plan covers two apps, which is enough to try the idea, and Pro unlocks the full trio plus unlimited profiles and spaces for a modest annual price. If you only use one account each and are on Mac or Windows, the official Notion and ChatGPT apps may be all you need. If you juggle accounts, work with clients, or use Linux, WebCatalog desktop apps are well worth a try.
