Chrome ChatGPT Helper solves a very specific irritation: the constant round trip of copying text out of a page, pasting it into ChatGPT, copying the answer back, and pasting it in again. The extension adds a customizable set of prompts to Chrome's context menu, so running a prompt is a matter of selecting text, right-clicking, and choosing the prompt you want. Results replace your selection in place, and your original text is automatically copied to the clipboard so a quick Ctrl + V restores it.
Setup requires your own OpenAI API key, which you paste into the extension's options page. From there you can choose between GPT-4 and GPT-3.5 Turbo — the developer notes that GPT-4 is smarter but more expensive — and add or delete prompts with unique names. Prompts support a $selection placeholder that inserts whatever text you highlighted, and the extension ships with built-in examples. Because the cost is paid directly to OpenAI, the developer recommends setting usage limits on your API account to avoid surprises.
The project is fully open source on GitHub, contains no tracking, and the developer states that it collects no data at all. Its last listing update was in April 2024, and it identifies only as a bridge between Chrome and ChatGPT, with responsibility for generated output and API costs resting with the user. It is best suited to people who already have an OpenAI key and want prompt-driven edits without leaving the page.
