DuckDuckGPT
DuckDuckGPT adds an AI chat sidebar and auto search summaries straight into DuckDuckGo results pages, free under MIT.
If DuckDuckGo is your daily engine, DuckDuckGPT is the lowest-friction way to get LLM summaries and in-page follow-up chat at $0, with readable MIT source and no permissions requested. The friction is real: a userscript manager is mandatory, Chromium installs need Developer Mode switched on, and Streaming Mode is broken under Violentmonkey and OrangeMonkey. Want chat history, file uploads or a native app? This isn't that.

Skip DuckDuckGPT if you use Violentmonkey or OrangeMonkey and need live streaming responses, or if you want a standalone assistant with conversation history and file uploads rather than a sidebar bolted onto DuckDuckGo.
With Proxy API Mode off — its default — the README says a ChatGPT account is required to fetch responses, so free access isn't entirely unconditional.
DuckDuckGPT costs $0 — it's an MIT-licensed userscript, not a subscription. That puts it below paid AI search tools and assistant tiers, and roughly level with other free KudoAI userscripts like GoogleGPT. If you want a standalone assistant with history, files and team controls, you'll pay for ChatGPT or Claude instead; DuckDuckGPT's whole pricing edge is that there is nothing to bill.

What is DuckDuckGPT?
DuckDuckGPT — DuckDuckGPT adds an AI chat sidebar and auto search summaries straight into DuckDuckGo results pages, free under MIT. Best for DuckDuckGo regulars who want LLM summaries without switching search engines, Privacy-conscious searchers avoiding extensions that request broad permissions, Power users already running Tampermonkey or ScriptCat. Free to use.
DuckDuckGPT is a free, MIT-licensed userscript that drops an AI chat sidebar and auto-generated search summaries onto DuckDuckGo results pages. It's built for people who already default to DuckDuckGo and want LLM answers without bouncing to a second tab — install a userscript manager, install the script, search like normal, and the bot engages in place. The scope is intentionally narrow. You get a chat panel on results pages, an auto summary for the query you just ran, a model dropdown for picking among the latest LLMs, follow-up questions without leaving the page, and responses that type out live via Streaming Mode. Proxy API Mode, off by default, returns text responses using the latest LLMs without needing a chatgpt.com account; with it disabled, a ChatGPT account is required to fetch responses. Browser coverage runs wider than most userscripts. The README lists Chrome and Chromium builds, Edge, Firefox and Gecko builds, Safari across macOS, iOS, iPadOS and visionOS, Android through Tampermonkey, Violentmonkey or ScriptCat, plus QQ Browser, Mises, Lemur, Quetta and Orion. Rendering relies on chatgpt.js with highlight.js, KaTeX and Marked — all MIT or BSD licensed — and the script adds no extension permissions and no tracking. One install-time caveat: the GitHub repository was archived on Aug 15, 2026 and is now read-only. Stars, forks, issues and the single open pull request are frozen history, and ongoing development moved to codeberg.org/KudoAI/duckduckgpt. This isn't a standalone chatbot — it's an augmentation layer for one search engine, closer to an AI-native search tab than to ChatGPT or Claude.

Behind the verdict
We'd reach for DuckDuckGPT when the search habit is already set and the goal is fewer tabs, not more AI. The auto summary answers most lookups before you click anything, and the sidebar means a follow-up question doesn't cost you a detour. For a privacy-leaning searcher who won't hand an extension broad permissions, the userscript model is the point, not a compromise. Where it bites is installation. Chromium users have to flip on Developer Mode in chrome://extensions before Tampermonkey or OrangeMonkey will run userscripts at all, and Opera users must explicitly grant the manager access to search page results. Neither is hard; both are the kind of step that stops a casual user cold. Budget five minutes for setup, not thirty seconds. Streaming Mode is the other sharp edge. It doesn't work in Violentmonkey or OrangeMonkey, so Firefox and Edge users who prefer Violentmonkey get responses that arrive all at once instead of typing out. If watching the text stream matters to you, pick Tampermonkey or ScriptCat. Mind the Proxy Mode tradeoff. Off by default, it requires a chatgpt.com account to fetch responses. Turning it on removes that requirement and is the documented fix when the OpenAI API is acting unreliable — a small switch with outsized effect on whether the tool works on a bad API day. The closest alternative is GoogleGPT from the same KudoAI family, which points the identical concept at Google rather than DuckDuckGo. If you split searches across both engines, you can run both scripts; there's no conflict to manage beyond your userscript manager's list. AmazonGPT covers shopping lookups the same way. Caveats worth stating plainly. The GitHub repo has been read-only since Aug 15, 2026, so don't file issues there — go to codeberg.org/KudoAI/duckduckgpt for current
Models under the hood
as of 2026-10-22
Limitations
- DuckDuckGPT is a userscript, so step one is installing a supported userscript manager such as Tampermonkey, ScriptCat, Violentmonkey or Stay — there is no click-to-install extension.
- Chromium users installing Tampermonkey or OrangeMonkey must enable Developer Mode in chrome://extensions, and Opera users must grant the manager access to search page results in opera://extensions.
- Streaming Mode is not supported in Violentmonkey or OrangeMonkey, so responses arrive all at once there.
- With Proxy API Mode disabled (the default), the README states a ChatGPT account is required to fetch responses; Proxy API Mode exists as the fallback when the OpenAI API is unreliable.
- The project relies on the underlying language models, so response speed and availability depend on those services.
- The GitHub repository was archived on Aug 15, 2026 and is now read-only — development, issues and releases moved to codeberg.org/KudoAI/duckduckgpt.

GeneratedReal-world workflow fit
Concrete scenarios for the personas DuckDuckGPT actually fits — and what changes day-one when you adopt it.
You already have Tampermonkey installed for unrelated scripts. You add the DuckDuckGPT userscript from the manager, search a library or error message on DuckDuckGo, and the AI sidebar plus an auto-generated summary appear on the results page — no new extension, no permissions prompt.
Outcome: You get a plain-language explanation of the error or API alongside the documentation links, without leaving the search tab or opening a chat app.
You keep DuckDuckGo as your default because you don't want an extension with broad permissions. You install DuckDuckGoGPT through a userscript manager on Firefox; the README notes there are no extension permissions and no tracking, and chat rendering is handled by Marked, highlight.js and KaTeX.
Outcome: You keep your existing search engine and privacy posture while gaining AI summaries on the queries that need them, rather than being pushed into an AI-native search product.
You run the same question through DuckDuckGo and flip between models using the model selection dropdown to see where answers diverge, and if the OpenAI API is unreliable you switch on Proxy API Mode so responses come back without a chatgpt.com account.
Outcome: You get a quick side-by-side read on how different LLMs treat a topic, inside the results page you're already on.
Use cases
- Get an instant AI explanation for a search query without leaving DuckDuckGo
- Summarize a topic from the results page using your chosen LLM
- Compare how different models answer the same question side by side
- Draft a code snippet or short piece of content while you're browsing search results
- Ask follow-up questions in the sidebar instead of opening a separate AI tab
- Fold AI summaries into an existing research workflow on DuckDuckGo
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.
DuckDuckGoGPT: about 2 minutes if you already run Tampermonkey or ScriptCat — install the script and search. Add 2–5 minutes if you need to install a userscript manager first, and another minute for Chromium users to enable Developer Mode in chrome://extensions. QQ Browser ships Tampermonkey and Violentmonkey pre-installed, so it's the fastest path. Safari and niche mobile browsers such as Quetta
Switching to or from DuckDuckGPT
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From ChatGPT in a separate tab: install the userscript, then run the same queries on DuckDuckGo and read the sidebar summaries instead of switching tabs.
- →From GoogleGPT: same KudoAI family and the same userscript manager, so you add DuckDuckGPT alongside it and it activates on DuckDuckGo rather than Google.
- →From browser AI search tabs: install Tampermonkey or ScriptCat, add the script, and set DuckDuckGo as your default engine so summaries appear where you already search.
- ↗To ChatGPT: when you need conversation history, file uploads and a native app, move the session to chatgpt.com and keep DuckDuckGPT for quick mid-search summaries.
- ↗To GoogleGPT: if you switch your default engine to Google, the same KudoAI userscript family covers it and your manager setup carries over.
- ↗To Codeberg for updates: point your watches and release checks at codeberg.org/KudoAI/duckduckgpt since the GitHub repository is read-only as of Aug 15, 2026.
