FAQ

Any questions?

Installation & Basic Setup

You can find SplitLook on the Chrome Web Store by searching “SplitLook,” or go directly via the “Install” button on our official website.

You need the desktop version of Google Chrome. Mobile Chrome does not support extensions.

We recommend pinning the SplitLook icon on your toolbar (clicking it splits the current tab).
Otherwise, no additional setup is required. It’s ready to use from the moment you install it.

Usually it’s fine, but there may be conflicts with extensions that also modify or split the page display. If so, try temporarily disabling one or the other.

Usage

Click the SplitLook icon on the toolbar, or the floating icon at the bottom right of the page to split the current tab horizontally. You can also select “Enable Page Split” from the right-click menu.

Some sites may have restrictions that block resizing. If it works on other pages but not on a specific one, that site’s unique settings might be causing it.

Yes. The top and bottom frames each have their own scroll, so you can view the top while independently navigating the bottom.

Just click the SplitLook icon again, or select “Disable Page Split” from the right-click menu to return to a single view.

Each tab maintains its own split on/off state, so if you return to a split tab after viewing another, it stays split.

Compatibility

As long as you have the desktop version of Google Chrome, it’s OS-independent. It works on both.

Mobile Chrome does not officially support extensions. It may change in the future, but currently it’s for desktop only.

Officially, SplitLook is developed for Chrome. It may be partially installable on Chromium-based Edge, but not guaranteed. A Firefox version is under consideration.

Tablet Chrome is generally treated like mobile, so it doesn’t allow extension installation. Unless a special “PC mode” is used, it’s not supported.

It works on most sites, but certain domains or authentication systems may block SplitLook. If it fails, the site’s own restrictions or security setup might be the cause.

Optional Features & Pricing

SplitLook’s core features are completely free. The standard split-screen view and independent scrolling are available at no charge for all users. Specialized add-on features tailored to specific websites are available for a fee. See the Optional Features section for details.

We currently offer a paid add-on called “ChatGPT Optimizer,” designed specifically for ChatGPT pages. It enhances your split-screen experience with jump-to-message buttons, message index displays, and more. We plan to add other website-specific optional features in the future.

Yes—ChatGPT Optimizer includes a 30-day free trial. During this period, you can use every feature of the ChatGPT Optimizer at no charge. After the trial ends, please purchase a license key to continue using it.

After installing SplitLook as a Chrome extension, simply turn on the desired add-on in the options page. You can open the options page from the extension toolbar icon, the right-click menu (context menu), or the “Manage” menu.

All payments are securely processed via Stripe using a credit card. To complete your purchase, click the “Purchase License Key” button in the Optional Features section. We do not accept bank transfers or checks.

The optional features are a one-time purchase, not a subscription. Once you buy a license key, the add-on is yours to keep—no monthly or annual fees.

A license key will be sent to the email address you provided during purchase. Open the SplitLook options page and click “Register License Key” to enter your key. A single license key can be used on up to 5 devices.

Currently only the ChatGPT Optimizer is available, but we plan to develop additional add-ons for other web services where SplitLook’s split-screen view offers significant benefits.

Please use the contact form to let us know which web services you’d like optimized and what features you need. Your feedback will guide our future development.

If you reinstall SplitLook, just enter the same license key to restore your purchase. Please keep your license key email safe. Remember, a single license key can be used on up to 5 devices.

Troubleshooting

On certain sites, domain restrictions or security settings may cause issues.
If it doesn’t work on all pages, try restarting Chrome and ensure SplitLook is up to date. Conflicts with other extensions could also be a factor—try disabling suspicious ones temporarily.

The top/bottom frames may be blocked or there could be script conflicts. If it’s fine on other sites, then it might be that particular site’s limitations.

Some sites’ scripts can interfere, leaving frames stuck. Try reloading the page or clearing cache to fix it.

This isn’t unique to SplitLook; having many tabs open can increase memory load in general. Close unnecessary tabs or disable other extensions to lighten the load.
