DuckDuckGPT
Add AI chat & search summaries to DuckDuckGo with latest LLMs
If you’re a daily DuckDuckGo user who wants AI summaries without leaving the page, DuckDuckGPT delivers for free. It’s open-source, privacy-respecting, and versatile across browsers. The caveats: you need a userscript manager, streaming mode doesn’t work in Violentmonkey/OrangeMonkey, and the project’s move to Codeberg means you’ll need to follow there for updates. Power users will love it; casual searchers might find the setup a chore.

About DuckDuckGPT
DuckDuckGPT is a free, open-source userscript that embeds AI chat and LLM-generated search summaries directly into DuckDuckGo results. If you’re privacy-conscious but want ChatGPT-like answers while you search, this layers a sidebar onto every query with AI responses and auto-summarized results, plus a model dropdown. You install it via a userscript manager (Tampermonkey, ScriptCat, Violentmonkey, OrangeMonkey, Stay, Userscripts) and then just search normally. The project has migrated from GitHub to Codeberg (codeberg.org/KudoAI/duckduckgpt) as of August 2026, so future updates live there while the GitHub repo remains read-only. Keep that in mind for where to get the latest version and report issues. Key capabilities include Proxy Mode, which lets you get responses without a chatgpt.com account if OpenAI’s API is acting up; when disabled, a ChatGPT account is required. Streaming mode works in most managers but not Violentmonkey or OrangeMonkey, and Chromium users need to enable Developer Mode for the script to run. The tool runs on chatgpt.js and other MIT-licensed dependencies, and it’s compatible with a wide range of browsers: Chrome, Firefox, Edge, Safari (including iOS/iPadOS/visionOS), plus niche ones like QQ, Mises, Lemur, Quetta, and Orion. Installation is straightforward: grab a userscript manager, install the DuckDuckGPT script, then visit duckduckgo.com and search. Mobile support exists via ScriptCat on Android and iOS, though it can be finicky. Compared to a browser extension like Perplexity, DuckDuckGPT is lighter with no extension permissions and more privacy-friendly, but it only augments DuckDuckGo—it’s not a standalone chatbot. If you live in DuckDuckGo, it’s a frictionless way to get AI help while keeping your search habits private; the tradeoff is the comfort with userscripts and managing a couple of tools.
Behind the Verdict
DuckDuckGPT is the kind of tool that either fits your workflow perfectly or feels like overhead. We’d reach for it when you’re a privacy-first searcher who spends hours in DuckDuckGo and wants quick AI answers without switching tabs or feeding data to a browser extension. The install process is capped at a few minutes if you already use Tampermonkey or ScriptCat. Once it’s running, the AI sidebar and auto-summaries genuinely speed up research. Proxy Mode is a clever safety net for when OpenAI’s API hiccups, saving you from a dead end if you don’t have a paid account. Where it bites: the userscript-manager requirement is the biggest hurdle. Casual searchers won’t bother, and if you’re not technical, troubleshooting stream issues on Violentmonkey might frustrate. Also, because the GitHub repo is archived and development moved to Codeberg, you’ll need to remember to check the new home for updates. That’s a small but real friction point. And while it’s great for search, it’s not a chatbot—you can’t open a separate window and have a back-and-forth conversation. For that, you’d want the actual ChatGPT interface. Compared to browser extensions like Perplexity, DuckDuckGPT is lighter (no extension permissions) and more privacy-preserving, but it only works on DuckDuckGo. If you’re married to Google or another engine, this won’t help. The closest alternative might be GoogleGPT, a sibling userscript for Google search, but that’s a different install. In practice, we’d pick DuckDuckGPT if DuckDuckGo is your daily driver; otherwise, it’s a skip. Open-source enthusiasts will appreciate the MIT license and active community, though the archive notice means you should verify the Codeberg repo for the latest features.

Setup time & first value
How long it actually takes to get something useful out of DuckDuckGPT — broken out by persona, not the marketing-page minute.
For a Chrome user with Tampermonkey already installed, setup takes about 5 minutes: install the script, enable Developer Mode if needed, and visit DuckDuckGo. On Safari with Stay or Userscripts, add maybe 10 minutes for the manager install. Mobile via ScriptCat can take 15-20 minutes due to extra steps.
