DuckDuckGo
As generative AI becomes increasingly popular, people are becoming more worried about their data privacy.While many users have become used to widely known AI assistants like ChatGPT and Gemini, a key question has come up: Who actually sees the conversations we have with AI?DuckDuckGo AI Chat
DuckDuckGo, a search engine company that is committed to privacy, has responded with its own solution: DuckDuckGo AI Chat (Duck.ai).DuckDuckGo AI Chat.
In addition to being free and requiring no registration, it also sets a new standard for privacy in interactions between users and AI.This article provides a detailed overview of the platform’s guiding principles, features, available models, and the key distinctions that make it different from other major AI services.DuckDuckGo AI Chat
What is DuckDuckGo AI Chat? DuckDuckGo AI Chat
DuckDuckGo AI Chat is a privacy-centered AI chat platform introduced by DuckDuckGo in 2025.It is not an independent AI model but rather a unified chat interface that lets users interact with advanced AI models from various companies, including OpenAI, Anthropic, and Mistral, all through one platform.
Unlike many other AI services, DuckDuckGo’s main advantage is that your chats are not used to improve the models, are not kept, and are not connected to your personal information.
DuckDuckGo serves as an anonymous middle layer between the user and the AI model providers.Before sending any requests, all personal details, including IP addresses, are entirely removed.DuckDuckGo AI Chat
Privacy Protection: Duck.ai’s Core Strength
To truly appreciate the worth of Duck.ai, it’s important to first understand the key differences in how it manages data compared to other widely used AI services.
The default method of anonymization
When you send a message to Duck.ai, DuckDuckGo’s servers first remove all personal information, like IP addresses, device details, and location data.This ensures that when the request gets to the servers of OpenAI or Anthropic, it looks like it came from DuckDuckGo, not from a specific user.As DuckDuckGo explains, “If a user provides personal information during a chat, no one—including DuckDuckGo and the model providers—can tell if it was the user or someone else who sent those messages.”
Agreement for Zero Data Retention
DuckDuckGo has made binding agreements with all model providers, requiring them to follow Zero Data Retention rules.Specifically, these providers must: remove prompts and responses right away after providing a response; not use any conversation data to train models; and not share any user data with other companies.
Some models, like gpt-oss-120b and Gemma 4 31B, which are hosted through Tinfoil, take this a step further by operating within Trusted Execution Environments.
This technical setup ensures that providers cannot access, keep, or use user data for training.Duck.ai refers to these models as having “Zero Provider Visibility.”
History of Localized Chat
Duck.ai’s “Recent Chats” feature keeps conversation history stored directly on the user’s device, not on DuckDuckGo’s servers or any other remote location.Users have the option to remove specific chat records or delete all of them at once through the “Fire Button.” They can also choose to pin up to five chats to the top of the list, which helps avoid accidentally deleting important conversations.
An overview of the models that are available
The free version of Duck.ai provides access to a range of models from some of today’s top AI companies, offering versatility for different tasks.Here is a list of models that are currently available at no cost to users, as listed on DuckDuckGo’s official support page:
- Anthropic Claude 4.5 Haiku: A lightweight and fast model from Anthropic, ideal for everyday conversations and quick replies.
- Mistral AI Mistral Small 4: A compact model from Mistral, known for its efficiency in performance.
- OpenAI GPT-5.4 nano / mini: A series of smaller, lightweight models developed by OpenAI.
- gpt-oss-120b: An open-source model that is hosted through Tinfoil, with the advantage of not revealing the service provider.
- Gemma 4 31B: Part of Google’s open-source model series, also available via Tinfoil hosting.DuckDuckGo AI Chat.
It has been reported that Duck.ai has configured GPT-5.6 Luna as the default model for free users.
However, this change has not yet been reflected on the official help page.Therefore, it is advised to check the model displayed on the actual user interface for the most accurate information.
Subscribers’ Advanced Models
DuckDuckGo provides paid subscription options called Plus and Pro, which give users access to more advanced models.
- Plus Plan: Users get access to the GPT-5.6 Terra model and the Claude Sonnet 4.6 model.
- Pro Plan: This plan includes all the features of the Plus plan, plus access to the Claude Opus 4.8 model and the GPT-5.6 Sol model.
It also offers higher levels of reasoning effort and double the usage limits compared to the Plus plan.
Beyond Text: Multimodal Skills
From being a text-only chat tool, Duck.ai has developed into a multimodal platform that supports a variety of interaction techniques.
Voice Communication
Duck.ai launched real-time voice chat features at the beginning of 2026. The AI is able to communicate with users.Voice communication occurs through an encrypted relay connection.Audio is sent only when speaking, and neither DuckDuckGo nor OpenAI keeps any recordings after the conversation ends.Voice data is not used to train any models.
It should be noted that the voice feature must be turned on manually by the user and is not available on the Firefox browser at this time.
Creating and Modifying Images
Duck.ai offers AI-powered image generation, enabling users to create images by choosing “New Image” and providing a description.They can also continue the conversation to make changes and adjustments.Additionally, image editing features have been introduced, allowing users to upload and edit images in JPEG, JPG, PNG, or WebP formats.All uploaded images are kept on the user’s local device, and any metadata or IP addresses are removed before the images are sent.
Uploading and Analyzing Images
While some models allow you to upload and analyze images, Duck.ai does not support non-image file types like spreadsheets or PDFs.
Personalizing Reactions: Adapting AI to Your Requirements
Duck.ai provides a useful personalization feature known as system prompt customization.Unlike similar options from OpenAI or Anthropic, which often require going through multiple layers of settings, Duck.ai allows you to easily access and adjust these settings directly within the prompt bar.
You can use the “Customize responses” option to modify the tone and length of the AI’s replies, choose a specific persona for the AI such as a copywriter, storyteller, or teacher, define your own role like parent, student, or writer, request the AI to ask clarifying questions, set nicknames for yourself and the chatbot, and include any additional instructions.
These custom settings are added to the default system prompts of each model, so you don’t have to set them up separately for every model.
All your custom preferences are stored locally and are never transmitted to any model providers.
How Duck.ai Works
Accessing the Service
Starting to use Duck.ai is very straightforward.
You can go straight to duck.ai or access it through the DuckDuckGo browser by using the Duck.ai button or menu located in the address bar.You don’t need to create an account or provide an email address—just open the website and begin using it right away.
Basic Workflow
Once you’re on the platform, you can choose from different AI models using the model selector at the top.
Type your question or instruction, and the AI will give you a response.If you want to save your conversation, the “Recent Chats” feature will automatically store it locally.However, if you prefer not to leave any trace of your activity, you can use the “Fire Button” at any time to clear everything.
Search Enhancement-DuckDuckGo AI Chat
Duck.ai offers Web Search enhancement.
When you turn this feature on while asking a question, the system includes real-time DuckDuckGo search results as part of the context, allowing the AI to provide answers based on the most up-to-date information.It’s important to note that performance with real-time news queries in voice chat mode is still limited, and the service might occasionally refuse to answer due to the knowledge cutoff date.
Benefits and Drawbacks: For whom is Duck.ai intended?
Key Advantages
Duck.ai’s main strength lies in its strong focus on privacy.
In a time when most AI services use user conversations to improve their models and store data for many years, Duck.ai stands out by promising no data storage and no use of user input for model training.This makes it a real alternative for those concerned about their privacy.Users can even use the service without creating an account, further reducing potential privacy concerns.
Another key benefit is its ability to combine multiple AI models in one place.
This allows users to easily compare how different models respond to the same question, making it a convenient tool for testing and evaluation.
The combination of free access, no account needed, and support for voice and image features makes Duck.ai the most accessible privacy-focused AI service currently available.
Limitations and Drawbacks
Duck.ai is not without its drawbacks.
The free version offers limited support for complex tasks such as detailed research, advanced coding, and multi-step problem-solving.In comparison to premium services like ChatGPT Plus or Claude Pro, Duck.ai operates more like a basic daily helper rather than a professional productivity tool.
One major limitation is the file upload restrictions.
It only supports images, and does not allow uploads of documents such as PDFs, Word files, or spreadsheets.Additionally, the voice chat feature is not yet supported on the Firefox browser.
Some users have noted that the quality of responses on Duck.ai can sometimes be less accurate than using the original models directly.
This might be due to the system’s use of an anonymous proxy and its privacy-focused prompts.
Conclusion
DuckDuckGo AI Chat presents a unique approach to AI products: it doesn’t need to be the most powerful, but it must guarantee complete privacy.
Instead of trying to match the capabilities of ChatGPT or Gemini in every area, it offers a different, privacy-centered experience.
A good alternative for users who place data privacy as their top priority is Duck.ai.If you need AI assistance with tasks like drafting emails, explaining ideas, or creating basic images, and you do not want your conversations used to improve future AI models, then Duck.ai is a service worth exploring.It demonstrates that protecting user data and offering useful features can go hand in hand—depending on how you define what is “good enough.”
Regarding the images: As an AI assistant, I cannot directly generate image files.
However, you can use Duck.ai’s image generation tool to create visuals for the article, which itself is a strong example of what is possible.Below are four suggested prompts you can copy directly into Duck.ai’s “New Image” tool to generate the images:
