What is Duck.ai?
Duck.ai is a privacy-focused AI chat portal launched by DuckDuckGo. Its official website summarizes it in one sentence as "Use ChatGPT, Claude, and other AIs, privately." It does not develop large models itself; instead, it aggregates models from vendors such as OpenAI, Anthropic, and Mistral into a single interface with an added layer of anonymization. What it sells is privacy, not model capabilities.
Who is it for?
- People who want to try various large models without registering an account or providing a phone number and email address
- Users who want an additional layer of anonymity when consulting sensitive matters such as health, legal issues, or personal affairs
- Professionals who are subject to internal compliance restrictions and find it inconvenient to send their questions directly to a specific model vendor
Key features
6Multi-Model Aggregation
The official website states "All models are anonymously provided by DuckDuckGo". The available models cover the GPT series, Claude, Mistral, Llama, etc. (the page examples mention GPT-5 mini and Claude Haiku 4.5), and it differentiates between various modes such as reasoning mode and image generation mode.
Anonymization and Metadata Removal
The official explanation states "All personal metadata (for example, your IP address) is removed before sending a chat to the AI provider", meaning that personal metadata such as your IP address will be removed before the chat is sent to the model provider.
Not used for training AI
Multiple places on the page emphasize that "Your chats are private, anonymized by us, and not used to train AI models", and state that agreements have been reached with various AI service providers to ensure that conversations are not used for model training.
Transparent Retention Policies
The retention policy of the AI provider will be indicated in the conversation, for example, "This AI provider does not store this conversation on its servers" or "The provider will delete data related to this conversation within 30 days".
Account-free usage
Marked as "Free, No account required" on the official website, you can start chatting by opening the webpage; if you need to retain conversations across devices, you can use the end-to-end encrypted Sync & Backup feature.
Conversation Management
Supports clearing and deleting individual conversations, exporting and sharing; the official website notes that opening a new model conversation will clear the current session, and older conversations will be deleted when the local storage quota is exhausted.
How to use Duck.ai
- It does not train models, but conversations are still forwarded to third-party providers.
- the official has marked the retention policies of each provider, and checking the privacy prompts in the conversations one by one is more reliable than reading the overall promotion.
- When it comes to sensitive information such as real names, ID numbers, and medical records, the safest approach is still not to input it—anonymization reduces the exposure surface, but it does not mean zero risk.
- In account-free mode, conversations are stored in the local browser storage by default, and they will be deleted together when browser data is cleared.
- For important conversations, remember to export them first or enable Sync & Backup.
- For stronger reasoning, pay attention to the usage limit: The official website notes that the usage cap for advanced models may be exhausted 2 to 5 times faster than that for regular models.
- Image generation has a separate content policy.
- The official reminder states that prompts must comply with Duck.ai's Terms of Service, which should be checked before commercial use.
- the official rules may also be adjusted.
