What is Chrome ChatGPT Helper?
Chrome ChatGPT Helper is an open-source Google Chrome browser extension that lets you directly invoke the OpenAI API to execute custom ChatGPT prompts on webpages—no need to switch tabs or copy-paste. Users can trigger it with a single right-click, automatically inject the prompt into the selected text, and receive the generated response. The original text is simultaneously saved to the clipboard, all without collecting or tracking any user data. This extension supports both GPT-3.5 Turbo and GPT-4 models, requiring users to configure their OpenAI API keys independently and recommending setting usage limits to avoid unexpected charges. The configuration interface can be accessed by clicking the extension icon in the address bar and selecting "Options," or by right-clicking anywhere on a webpage and choosing "Edit Prompts." All prompts support the $selection placeholder, allowing dynamic insertion of the currently selected text into the prompt, with built-in examples covering practical scenarios such as email polish and joke generation.
Key features
Supports invoking preset prompts with a right-click in any text box on a webpage; after selecting text, the AI-generated result automatically replaces the selected content, while the original text is saved to the system clipboard for easy rollback (Ctrl+V).
Completely open-source and zero-data-collection: contains no tracking code, does not upload user input, output, or browsing behavior, and its privacy policy explicitly states that data is neither sold nor used for unrelated purposes.
Use cases and audience
Ideal for developers, content editors, marketers, and everyday office users who frequently rely on ChatGPT to process text on webpages.
- Select text on a webpage, then use a right-click menu to invoke ChatGPT with a custom prompt, rewriting emails into a professional tone.
- Select text on a webpage, then generate a joke with one click from the right-click menu and replace the original text.
- Before posting on Reddit, process the selected text using a custom prompt; first switch to Markdown mode to ensure proper pasting.
Any text selected by the user on a webpage, along with custom prompts configured by the user that include the $selection placeholder.
The response text generated by ChatGPT based on the prompt will directly replace the originally selected text on the webpage, while the original selected text is automatically copied to the system clipboard.
Frequently asked questions
Does this extension collect or upload my data?
Does not collect, upload, or track any user data; the developer explicitly states that data will not be sold to third parties and is used solely to enhance core functionality.
Why can’t the results be pasted correctly when used on Reddit?
Due to Reddit’s rich-text editor having exceptional support for paste events, you must first manually switch to Markdown mode before using this extension.
How to use
- 01
After installing the extension, click the extension icon in the upper-right corner of your browser → select “Options” to enter the settings page, or right-click anywhere on the webpage → choose “Edit Prompts.”
- 02
On the settings page, enter a valid OpenAI API key and make sure your account has sufficient funds; it’s recommended to set usage limits to prevent unexpected charges.
- 03
In the “Model” option, choose GPT-4 (smarter but more expensive) or GPT-3.5 Turbo (more cost-effective).

Click “Add Prompt” to add a custom prompt, using the $selection placeholder to insert the selected text; all changes will only take effect after clicking “Save.”
Pricing and availability
This extension itself is free, but invoking ChatGPT consumes credits from your OpenAI account; the GPT-4 model costs more than GPT-3.5 Turbo. Users are responsible for managing their API keys and usage limits to avoid overage charges.
