How to set up Page Assist with Ozeki AI Gateway
This guide walks you through installing the Page Assist browser extension and connecting it to Ozeki AI Gateway as a custom model provider. By following this tutorial, you will learn how to install the extension from the Chrome Web Store, add Ozeki AI Gateway using the OpenAI Compatible API option, and verify the connection by sending a test prompt directly from your browser.
What is Page Assist?
Page Assist is a free, open-source browser extension that adds a sidebar and web UI for interacting with AI models directly from any webpage you visit. It supports Chromium-based browsers including Chrome, Brave, and Edge. Page Assist is designed to work with locally hosted AI providers and it supports OpenAI-compatible API endpoints. All your chat data is stored locally in the browser, so nothing is sent to external servers.

Steps to follow
We assume Ozeki AI Gateway is already installed on your system. You can install it on Linux, Windows or Mac.
Video tutorial
The following video shows how to install the Page Assist extension and configure it to work with Ozeki AI Gateway step-by-step.
Step 1 - Install Page Assist extension
Open your browser and navigate to the Page Assist listing on the Chrome Web Store. Review the extension details and click the Add to Chrome button to begin the installation (Figure 1).
A confirmation dialog will appear listing the permissions the extension requires. Click Add extension to confirm and complete the installation (Figure 2).
Once installed, click the puzzle-piece icon in the Chrome toolbar to open the extensions menu. Find Page Assist in the list, click the pin icon to keep it visible in the toolbar, then click the Page Assist icon to open its interface (Figure 3). Pinning the extension makes it easier to access on future visits.
Step 2 - Configure provider
Inside the Page Assist interface, open the settings by clicking the gear icon. This will take you to the configuration panel where you can manage providers and other options (Figure 4).
Locate the OpenAI Compatible API provider section, then click Add Provider to open the configuration form (Figure 5). This option enables Page Assist to communicate with any API that follows the OpenAI format.
Fill in the provider details using the values below, then click Save to store the
connection (Figure 6). Replace ozkey-abc123 with the
API key you created.
Page Assist will attempt to connect to your gateway and retrieve the list of available models.
Provider Name: Ozeki AI Gateway Base URL: http://localhost/v1 API Key: ozkey-abc123
You will see a list of available models, select the ones you want to make available in the chat interface. You can enable multiple models and switch between them at any time from the chat view (Figure 7).
Step 3 - Test Page Assist
Return to the chat interface and start a new conversation. Open the model selector and choose one of the models you enabled from Ozeki AI Gateway (Figure 8).
Type a test question in the chat input field and press Enter or click the send button to submit the prompt (Figure 9). Page Assist will forward the request to Ozeki AI Gateway, which will route it to the selected model and stream the response back to the extension.
The AI response will appear in the chat window, confirming that Page Assist is successfully connected to Ozeki AI Gateway and routing requests through your configured model (Figure 10).
To sum it up
You have successfully installed Page Assist and configured it to use Ozeki AI Gateway as its model provider. All prompts sent through Page Assist are now routed through your gateway, giving you centralised control over API access, model selection, and usage monitoring. Because Page Assist works as a browser extension, you can open it on any webpage and use AI assistance in context without switching applications.
