Product preview
Duck.ai
What it is
Duck.ai is a private AI chat service from DuckDuckGo. It lets you talk to popular third-party models, with DuckDuckGo acting as an anonymizing go-between so the model providers do not see who you are. DuckDuckGo says it does not store prompts or train on them, and recent chats are saved locally on your device rather than on remote servers. You can pin chats, delete them individually or with the Fire Button, and use features like image creation and voice chat. Free models in October 2026 include Claude 4.5 Haiku, GPT-6 Luna, GPT-5.4 mini, Mistral Small 4, gpt-oss-120b and Gemma 4. DuckDuckGo subscribers get advanced models such as Claude Sonnet 5.5 and GPT-5.6 Terra, with Opus on Pro.

Editor's notes
More context from AI BirdView
Duck.ai is a free, private AI chat from DuckDuckGo that gives you access to several well-known models without creating an account or tying conversations to your identity. DuckDuckGo forwards your prompts to the model providers in anonymized form, does not store them on its servers, and keeps your recent chats on your own device. That makes it one of the lowest-friction ways to use AI chat privately.
What is Duck.ai used for?
Duck.ai covers quick, everyday AI tasks for people who do not want a chatbot account or a history stored in the cloud.
- Asking quick questions and getting explanations without signing in
- Composing and editing emails or short documents
- Summarizing pasted text
- Switching between models from OpenAI, Anthropic, Mistral and open-weight models
- Creating images and using voice chat
- Deleting history with the Fire Button or pinning up to five chats
Who Duck.ai is best for
Duck.ai suits DuckDuckGo users, privacy-conscious people who want occasional AI help, and anyone who wants to try different models without accounts. DuckDuckGo subscribers who already pay for its VPN and data removal services get stronger models as part of that bundle. Heavy users who need projects, long-term memory, file-heavy workflows or team sharing will want a fuller assistant.
Duck.ai pricing
Duck.ai is free to use with a set of smaller models and daily usage limits. Advanced models come with the DuckDuckGo subscription. According to DuckDuckGo's help pages, the Plus plan is $9.99 per month or $99.99 per year and bundles a VPN, advanced Duck.ai models, Personal Information Removal and Identity Theft Restoration. Pro is $19.99 per month or $199.99 per year and adds Claude Opus, higher reasoning effort and twice the Duck.ai usage limits of Plus. Prices are localized outside the US. Model lineups change often, so check the help center for the current list as of October 2026.
Limitations to keep in mind
- Free models are lighter versions, so complex reasoning may be weaker
- Usage limits apply daily, and DuckDuckGo publishes them separately
- Local-only history means chats do not follow you to another device unless you use DuckDuckGo's sync features
- Duck.ai cannot be purchased on its own apart from the broader subscription
Duck.ai vs alternatives
ChatGPT offers the strongest all-round features, memory and integrations, and it is the better pick for heavy daily use. Perplexity is the better tool when you need cited web research. Brave Leo AI is a comparable privacy option built into the Brave browser. Poe gives access to many more models for a subscription. Duck.ai wins for quick, anonymous chats with no account and no server-side history.
Tips for getting started with Duck.ai
Try a couple of the free models on the same question to see which style suits you, since each provider writes differently. Pin the chats you want to keep before clearing history with the Fire Button. If you already pay for a DuckDuckGo subscription, activate it in Duck.ai to unlock the advanced models.
