Setup
Prerequisites
Before using articleSummary.js, the following are required:
- A registered Wikipedia account
- JavaScript enabled in the browser
- A Google Gemini API key
The script runs entirely in the user's browser and does not require any browser extensions or userscript managers.
Obtaining a Google Gemini API Key
The script uses Google's Gemini API to generate article summaries. Each user must supply their own API key.
Steps to obtain an API key
- Visit Google AI Studio
- Sign in with a Google account.
- Open the API Keys section from the dashboard.
- Create a new API key.
- Copy the generated key.
No billing information is required for basic usage at the time of writing, although usage limits and policies are determined by Google.
Adding the Script to common.js
Wikipedia allows registered users to run personal JavaScript by editing their user common.js page. Steps
- Log in to Wikipedia.
- Navigate to your personal common.js file.
- Add the following code to your common.js file.
importScript('User:Overandoutnerd/Scripts/articleSummary.js');
- Save the page.
- Reload Wikipedia pages (bypass cache if necessary).
The script will now load automatically on Wikipedia pages while you are logged in.
First-Time Use
When the Generate AI Summary button is clicked for the first time:
- The script will prompt the user to enter their Gemini API key.
- The key is stored locally using localStorage in the browser.
- The key is never sent to Wikipedia or shared with other users.
If the stored key is removed from localStorage, the prompt will appear again.
API Key Storage and Privacy
- The API key is stored only in the user's browser.
- The key is used solely to send requests directly to Google's Gemini API.
- Wikipedia servers do not receive or store the API key.
- All generated summaries remain local and are not saved or published.
Users are responsible for complying with Google's API usage limits and terms of service.
