ChatGPT for Google

ChatGPT for Google (now branded AI Chat for Search at aichat4search.com) is a Chrome extension that injects conversational AI answers alongside results from Google, Bing, DuckDuckGo, Brave, Yandex, Kagi, Searx and a handful of regional engines like Baidu and Naver. Instead of forcing you to flip between tabs, it shows GPT-4, Claude 2 and other model responses in a sidebar next to the standard SERP, and bundles utilities for summarizing YouTube videos and PDFs.

The extension is free and aimed at researchers, students and heavy searchers who want a second opinion to the ten blue links without switching context. You bring your own provider accounts (OpenAI, Anthropic, etc.) so it's a thin client over models you already pay for rather than a hosted inference service. It claims roughly two million users, which puts it among the more established entries in this crowded category of search-sidebar AI add-ons.

Beyond search, it ships extras: image generation and editing, AI text detection, mind mapping, a math solver and a grab-bag of PDF conversion tools. There's no public API and no open-source codebase, so it lives or dies as a packaged browser extension, and the redirect from the original chatgpt4google.com domain to aichat4search.com suggests an ongoing rebrand away from the OpenAI-adjacent name.
