What is Duckduckgpt?
DuckDuckGPT is a userscript that adds AI chat and search summaries directly into DuckDuckGo search results. Powered by GPT-4o and the latest LLMs, it displays ChatGPT answers in a sidebar alongside DuckDuckGo search results, allowing users to engage with AI without leaving their privacy-focused search engine. The tool was developed by KudoAI and is available as an open-source project on GitHub.
Key features include Proxy API Mode (which returns GPT-4o text responses without requiring a ChatGPT account), streaming mode for real-time responses, multi-browser compatibility (Chrome, Firefox, Edge, Safari, and mobile browsers), and support for multiple userscript managers like Tampermonkey, ScriptCat, and Violentmonkey. The tool also supports asking questions from any site, not just DuckDuckGo.
DuckDuckGPT is designed for privacy-conscious users who already use DuckDuckGo and want AI-enhanced search results. It appeals to researchers, students, developers, and anyone seeking quick AI-generated answers without switching tabs. The open-source nature allows users to inspect the code and contribute to development.

Frequently asked questions about Duckduckgpt
What is DuckDuckGPT?
DuckDuckGPT is a userscript that brings ChatGPT AI capabilities to DuckDuckGo search. It displays AI-generated answers in a sidebar alongside DuckDuckGo search results, powered by GPT-4o and the latest LLMs. The tool enhances DuckDuckGo with AI chat and search summaries without requiring users to leave their privacy-focused search engine.
How do I install DuckDuckGPT?
First, install a userscript manager like Tampermonkey, ScriptCat, or Violentmonkey for your browser. Then install the DuckDuckGPT userscript, which will load in your manager. Finally, visit duckduckgo.com, type your search query, and engage with the bot. The installation works on Chrome, Firefox, Edge, Safari, and various mobile browsers.
Do I need a ChatGPT account to use DuckDuckGPT?
A ChatGPT account is required when Proxy Mode is disabled (the default setting). However, if you enable Proxy API Mode, you can get GPT-4o text responses without needing any chatgpt.com account. Proxy Mode is disabled by default but can be enabled if OpenAI API is unreliable or if you don't have a ChatGPT account.
What browsers are supported?
DuckDuckGPT works on Chrome, Firefox, Edge, Safari (macOS, iOS, iPadOS, visionOS), and many mobile browsers including Edge Android, Firefox Android, Kiwi, Mises, Lemur, Quetta, and Orion. Each browser requires a compatible userscript manager like Tampermonkey, ScriptCat, Violentmonkey, OrangeMonkey, Stay, or Userscripts.
What is Proxy Mode?
Proxy API Mode is a feature that returns text responses using GPT-4o without requiring a ChatGPT account. It is disabled by default. When enabled, it allows users to fetch AI responses even without logging into ChatGPT. You should enable Proxy Mode if the OpenAI API is acting unreliable or if you don't have a ChatGPT account.
Is DuckDuckGPT free?
Yes, DuckDuckGPT is completely free to use with no subscription fees, paid tiers, or licensing costs. It is an open-source userscript developed by KudoAI. The only potential cost is if you choose to use ChatGPT Plus for higher usage limits, but the extension itself has no charges.
What is Streaming Mode?
Streaming Mode provides real-time response streaming for AI answers, making the experience more interactive. However, Streaming Mode is not supported in Violentmonkey and OrangeMonkey userscript managers, so users of these managers should use Tampermonkey or ScriptCat for the full experience.
Can I use DuckDuckGPT on mobile?
Yes, DuckDuckGPT works on mobile browsers including Safari on iOS/iPadOS, Firefox Android, Edge Android, Mises, Lemur, Quetta, and Orion. You need to install a mobile-compatible userscript manager like Stay, Userscripts, Tampermonkey, or ScriptCat depending on your browser and platform.
Is DuckDuckGPT open-source?
Yes, DuckDuckGPT is open-source and available on GitHub under the KudoAI organization. The repository has over 260 stars and accepts contributions. The code is transparent and users can inspect, modify, or contribute to the project. Dependencies include chatgpt.js, highlight.js, KaTeX, and Marked, all under permissive licenses.
Why does it show loading when I'm not logged in?
When Proxy Mode is disabled (the default), DuckDuckGPT requires a ChatGPT account to fetch responses. If you are not logged into ChatGPT, the tool will show a loading state because it cannot retrieve AI responses without authentication. Enabling Proxy Mode or logging into ChatGPT will resolve this issue.
