How much does ChatGPT for Google cost?

The extension itself is free. However, you must provide your own accounts with underlying AI providers like OpenAI or Anthropic, meaning you pay for the model usage separately.

Which AI models does it support?

It supports a multi-model approach, including GPT-4, Claude 2, and other large language models. You can view responses from these different providers in the sidebar next to your search results.

Is there an API or open-source code available?

No. There is no public API and no open-source codebase. The tool functions strictly as a packaged browser extension, so it cannot be integrated into custom software stacks or self-hosted environments.

What search engines does it work with?

It works with Google, Bing, DuckDuckGo, Brave, Yandex, Kagi, Searx, and regional engines like Baidu and Naver. It injects AI answers directly into the results page for these platforms.

What extra features does it offer besides search?

Beyond search augmentation, it includes utilities for summarizing YouTube videos and PDFs, image generation and editing, AI text detection, mind mapping, a math solver, and various PDF conversion tools.

In short

A free Chrome extension that displays GPT-4 and Claude answers in a sidebar next to Google, Bing, and other search results, requiring your own AI provider accounts.

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.
