Duck.ai
Free AI chat from DuckDuckGo that passes your questions to several models anonymously, without an account.
- Free plan or free version
- Mobile app
These tools offer AI chat and AI search with stricter handling of your data than the mainstream defaults. The approaches differ: some pass your questions to models without linking them to your identity, some encrypt your chat history, and some promise not to use your conversations for training.
DuckDuckGo's Duck.ai lets you chat with several models without an account. Proton's Lumo is built around encrypted history and comes from a company known for encrypted email. Kagi Assistant is part of a paid search service with no ads. Brave Search runs its own index and can show AI answers with sources.
Privacy claims are worth reading closely. Check what is logged, for how long, where it is processed, and whether third-party model providers are bound by the same terms. A tool can protect your identity and still send the content of your question to a model provider, so avoid pasting secrets either way.

None of these remove the need for care with sensitive material. Treat them as a better default for everyday questions, and keep confidential work in tools your organization has approved.
These tools can sit alongside a mainstream assistant rather than replace it. Many people use a privacy-minded option for everyday questions about health, money or family, and keep a mainstream tool for work that needs file uploads or longer memory. Whatever you choose, turn off chat history where the setting exists if you do not need it, and delete old conversations you no longer use.
Privacy policies change, so check them again after major product updates.
Several give access to well-known models, so answers can be similar. Features such as file uploads, memory or agent modes may be more limited, often by design.
It means the question is not tied to your identity by the service. The text still goes to a model provider to be answered, so do not paste passwords, client data or other secrets.
Duck.ai works without one. Lumo and Kagi Assistant need accounts, and Kagi is a paid service. Brave Search works without an account in any browser.
Only if your employer allows it. Privacy terms for personal use are not the same as a company data agreement, so check which AI tools are approved before you paste any work material into one.
