Janitor AI Web: Access Janitor AI Online Without Download

Janitor AI started as a website and the web version is still the most complete way to use the platform. You don't need to download anything. You don't need an app. Open a browser, go to janitorai.com, log in, and you're chatting with AI characters.

About 100 million people visit the site every month through their browser. The web version gets new features first, has more configuration options than the mobile app, and is the interface that the development team builds for before anything else. Here's what you need to know about using Janitor AI on the web.

Getting Started on Janitor AI Web

Go to janitorai.com in any modern browser. Chrome, Firefox, Edge, and Safari all work. No browser extensions are required, though you might need to disable aggressive ad blockers if the site's scripts don't load properly.

Create an account with an email address or sign up through Google. Email registration sends a verification link — check your spam folder if it doesn't arrive in a few minutes. You need to verify before you can start chatting.

Once logged in, the homepage shows trending and popular characters. The search bar at the top lets you filter by keywords and tags. The left sidebar or top navigation (depending on the current UI layout) gives you access to your chats, created characters, and settings.

The web version requires no installation, no storage space beyond browser cache, and no system permissions. It runs in a browser tab and uses the same account system as the mobile app — everything syncs between devices automatically.

What the Web Version Does Better Than the App

The Janitor AI web version has several advantages over the mobile app, especially for power users and character creators:

Full proxy and API configuration. Setting up external AI models through the proxy system is significantly easier on desktop. The API settings page gives you full control over model selection, proxy URLs, API keys, and generation parameters like temperature and max tokens. These options technically exist in the mobile app but the interface is cramped.
CSS customization. The character profile CSS editor works better with a full keyboard and screen. If you're customizing character profiles with templates or writing your own CSS, do it on desktop.
Character creation. Writing detailed character definitions is faster with a keyboard. Copy-pasting from notes, editing long text blocks, and formatting personality descriptions are all much smoother on desktop than mobile.
Chat history management. The web version makes it easier to scroll through long chat histories, copy-paste sections you want to save, and manage multiple ongoing conversations. The larger screen simply accommodates more information.
Multi-tab workflow. You can keep multiple characters open in different browser tabs, which is useful for creators who are working on several character definitions simultaneously or users who maintain parallel roleplays.

Features Exclusive to the Web Version

Some features only work on the web or were released there first:

API response debugging. When an external model returns an error, the web version often shows more detailed error messages than the app. This matters when you're troubleshooting proxy configuration or API key issues.
Browser developer tools integration. If you're customizing CSS or debugging page behavior, having access to your browser's developer console (F12) is essential. This is desktop-only territory.
Full-screen chat mode. The web version's layout uses screen real estate better for immersive reading. Long-form roleplay benefits from a wide reading column that doesn't exist on a phone screen.
Import/export workflows. Copying character definitions between the platform and external text editors, managing backups of your character library, and sharing definitions with other creators all work more smoothly through the web interface.

Performance and Browser Compatibility

Janitor AI's web version handles most of its processing server-side, so your device's specs matter less than your internet connection. The AI model runs on Janitor AI's servers or your configured API provider — your browser just displays the results.

Chrome and Chromium-based browsers (Edge, Brave, Opera) offer the smoothest experience. The platform is built and tested primarily against Chrome's rendering engine.
Firefox works well but occasionally has minor layout differences with CSS customization.
Safari on macOS is fully supported. Older versions of Safari on iOS may have layout quirks, but these are cosmetic rather than functional.
Mobile browsers on both Android and iOS support the full web version. It's responsive and adapts to smaller screens, though the experience is tighter than the desktop layout.

The site doesn't use heavy client-side processing. Memory usage is typical for a text-heavy web application — a few hundred megabytes of RAM for active tabs with long chat histories.

Security and Privacy on the Web Version

Your conversations on Janitor AI Web are tied to your account and stored on the platform's servers. The data passes through Janitor AI's infrastructure when you use JanitorLLM and through your configured API provider when you use an external model.

Use a strong, unique password. The web version is accessed through browser login, so your account security depends on your password strength. Enable two-factor authentication if Janitor AI offers it — check the account security settings.
Clear browser data if using a shared computer. Janitor AI saves login sessions. On a shared or public computer, log out after each session and clear the browser cache.
External API keys are sent to the model provider directly. When you configure a proxy with your own API key, your conversations route from your browser to Janitor AI's proxy layer to the model provider. The model provider sees your chat content. Janitor AI's proxy layer sees it too. This is inherent to the proxy architecture and applies to all platforms that support external model integration.

Conclusion

Janitor AI Web is the primary version of the platform and the best place to start. It's free, requires no download, and gives you access to every feature the platform offers — including proxy configuration, CSS customization, and detailed character creation tools that are harder to use on mobile.

If you mostly use Janitor AI on your phone but want to set up external AI models or customize character profiles, spend 10 minutes on the desktop web version to configure everything. Your settings sync to the mobile app and you won't need to touch them again.

Ready to start? Go to janitorai.com and create an account. Or if you prefer having a dedicated app, download the official Janitor AI app from APKPure. Your account and all your data carry over between the web version and the mobile app seamlessly.
