Best for

Pick ChatGPT for Google if you want GPT-4 or Claude answers rendered next to your normal Google or Bing results without juggling tabs.

Skip if

Skip it if you need an API, an open-source stack, or you're uncomfortable letting a third-party extension read every search you run.

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.

Editor's take

A pragmatic sidebar-AI extension that does the obvious thing well: dual-pane answers next to real search results. The bring-your-own-key model keeps it free but means it's really a UI layer, not a product with its own moat, and the rebrand away from the ChatGPT name is worth watching.
