WebChatGPT

WebChatGPT is a Chrome extension that injects real-time web search results into your ChatGPT conversations, working around the model's knowledge cutoff by scraping relevant search snippets and pasting them as context before your prompt. It also ships with a prompt library of hundreds of pre-written templates and lets you save custom prompts, all from a panel that sits directly under the ChatGPT input box. The extension supports multiple chat assistants including ChatGPT, Claude, Bing AI and Bard/Gemini.

The extension is free and has over 1,000,000 active users with a 4.2-star rating across 3,300+ reviews, putting it among the most-installed AI productivity extensions on the Chrome Web Store. It's best for casual researchers and students who want a 'cheap and free' way to ground LLM answers in current sources without paying for ChatGPT Plus's browsing tool or a Perplexity subscription. Power users will quickly outgrow it: search quality depends on whatever scraped snippets fit in the context window, and there's no agentic deep-research behavior.

It runs entirely in your browser (no server-side processing), and the developer states no data is sold or used outside core functionality. Caveats: it requires broad website permissions, breaks occasionally when ChatGPT's UI changes, and has been overtaken in capability by built-in browsing modes from OpenAI, Anthropic and Google.
