Duck AI, also known as DuckDuckGo AI Chat, is the artificial intelligence chatbot developed by DuckDuckGo that has revolutionized the market by offering a privacy-focused alternative to giants like ChatGPT.
This tool allows you to interact with multiple AI models without creating an account and without your conversations being tracked or used to train models.
What is Duck AI?
Duck AI is an AI-powered chatbot fully integrated into the DuckDuckGo search platform that uses advanced machine learning techniques to provide fast, accurate, and contextual answers on a wide variety of topics.
What truly sets this tool apart is its strict policy of not collecting, storing, or tracking users' personal data.
The service allows you to switch between several AI models including GPT-4o mini, o3-mini, Llama 3.3, Mistral Small 3 and Claude 3 Haiku, allowing you to interact with each model anonymously by hiding your IP address.
Main Features
Duck AI offers access to multiple AI models without requiring account registration, allowing for completely anonymous chatting.
The platform has a local chat history stored directly on your device, not on remote DuckDuckGo servers, which can be disabled if you wish.
Key features include automated data processing that minimizes manual input and errors, customizable workflow templates, real-time analytics dashboards, and integration capabilities with popular software and cloud services.
DuckDuckGo has announced that in the coming weeks (starting in January 2026) it will add web search support to improve answers, as well as voice interaction on iPhone and Android and the ability to upload images to ask questions about them.
Privacy and Security
Privacy is Duck AI's standout feature: it doesn't track your IP address, and conversations aren't linked to your personal identity. Your chats aren't used to train AI models, ensuring your data remains private. DuckDuckGo has agreements with each AI provider to guarantee your data isn't used for training. Unlike ChatGPT, which stores data (though it offers an opt-out option), Duck AI implements a zero-logs model where no data is stored.
Available AI Models
Free Version
The free version of Duck AI allows access to basic models such as the GPT-4o mini, o3-mini, Llama 3.3, Mistral Small 3, and Claude 3 Haiku at no cost. This version is fully functional for most users who need quick answers and basic research.
Paid Version (DuckDuckGo AI+)
For $9.99 USD per month or $99 USD per year, subscribers can access more advanced AI models, including OpenAI's GPT-40 and GPT-5, Anthropic's Claude Sonnet 4, and Meta's Llama Maverick. DuckDuckGo's subscription maintains the same price and also includes VPN, personal data removal, and identity restoration. This price is more competitive than maintaining multiple separate AI subscriptions, many of which cost around $20 per month.

How to Switch Between Models in Duck AI: Step-by-Step Guide
Switching between different AI models in Duck AI is a simple process that allows you to compare responses and find the model that best suits your needs. This feature was introduced in April 2025 after being one of the most requested features by users.
Method 1: Change Model When Starting a Conversation
The first time you access https://duck.ai , the system will ask you which model you want to use. At that point, you can select from the available options: OpenAI's GPT-4o mini, Meta's Llama 3.3 70B, Anthropic's Claude 3 Haiku, Mistral Small 3, or OpenAI's o3-mini reasoning model (in beta). Simply click on your preferred model to begin your conversation.
Method 2: Changing the Model During a Conversation
Once you've started a conversation with Duck AI, you can switch models at any time without losing context. To do this, look for the "Switch model" button located at the top of the chat window. Clicking this button will open a menu with all available models. Select the new model you want to try, and the conversation will continue in that model.
Method 3: Comparing Responses from Different Models
Duck AI also offers the ability to compare how different models respond to the same question. To use this feature, ask your initial question to one model and then click the repeat button at the top of the chat window. This will allow you to see how other models would answer the same question, making it easy to directly compare the responses of GPT, Claude, Llama, and Mistral.
Default Model Configuration
Currently, Duck AI defaults to the ChatGPT (GPT-4o mini) model every time you start a new session. Although some users have requested the ability to change this default, there is currently no official option to set a different model as the default. However, changing the model is so quick that it only requires one additional click at the start of each session.
Additional Customization of Responses
In addition to switching between models, Duck AI lets you customize the tone and length of responses through system settings. This customization is stored locally on your device and is automatically applied to all models you use, without needing to configure each one separately. To access this feature, look for the settings button in the Duck.ai prompt bar.
Advantages of Switching Between Models
Each AI model has its own strengths and moderation levels. Switching between them allows you to find the most suitable model for each type of query: some are better for creative tasks, others for technical analysis, and still others for more conversational responses. This flexibility, combined with DuckDuckGo's commitment to privacy, makes Duck AI a versatile tool for comparing the capabilities of different AI providers without compromising your anonymity.
Conclusions about this tool
Duck AI represents a solid, privacy-focused alternative to conventional AI chatbots.
If privacy and data control are your priority, Duck AI offers a secure and anonymous chat option. However, if you need more features and versatility, ChatGPT remains the most comprehensive and powerful choice.
The right tool depends on your priorities: privacy, features, or a balance between the two. For most everyday tasks and privacy-conscious users, Duck AI has established itself as a valuable tool that combines functionality with uncompromising data protection.
