Project unmaintained since February 2023, requires an OpenAI API key or active ChatGPT Plus account to function.

In plain English

ChatGPT for Google was a browser extension that showed ChatGPT responses alongside results from Google and other search engines. When you searched for something, the extension would simultaneously query ChatGPT and display its answer in a panel next to the regular search results, so you could see the AI response without switching tabs or opening a separate tool. The extension worked with ten search engines beyond just Google, including Bing, DuckDuckGo, Baidu, Yahoo, Brave, Naver, Yandex, Kagi, and Searx. It supported both the official OpenAI API and ChatGPT Plus accounts. Responses were rendered with proper text formatting and code highlighting. Other options included dark mode, a copy-to-clipboard button, a custom trigger mode to control when ChatGPT would respond, and the ability to switch display language. Installations were available through both the Chrome Web Store and the Mozilla Add-on Store. For Brave browser users, there was a known quirk: a fingerprinting-protection setting needed to be disabled in Brave's shield settings for the extension to function. Opera users needed to explicitly enable search page access in the extension management page. The project is no longer active. As of February 2023, it was acquired and the repository has not been updated since. The original author moved on to a separate project called ChatHub. The source is written in TypeScript, built with npm, and produces separate output folders for Chromium-based browsers and Firefox.
