   New feature

   Duck.ai added chat sync, which connects chats across devices and browsers with end-to-end encryption and no account, email or password required.

   What this means for you: Duck.ai can now keep your chats in step across your phone, laptop and different browsers. The chats are end-to-end encrypted, which means only you can read them, and you don't need an account, email or password.

   Why it matters: It comes after Duck.ai added private chat sharing on Oct 7, which also works without an account.

   How to use it: Open Duck.ai, then go to Settings, then Chats, then Sync & Backup, and turn it on.

   I use Duck.ai on more than one device and just learned it has chat sync with end-to-end encryption and no account needed. Walk me through turning it on in Settings, then Chats, then Sync & Backup, and help me decide which of my chats are worth keeping synced. My devices are: [list devices].

   New model

   Duck.ai added OpenAI's GPT-6 Luna model, available free with no account needed.

   What this means for you: Duck.ai now offers GPT-6 Luna, which DuckDuckGo describes as OpenAI's most efficient GPT-6 model. You can chat with it without paying or making an account.

   How to use it: Go to Duck.ai and pick GPT-6 Luna. It is free and anonymous, and no account is needed. Like all AI on DuckDuckGo, it is optional.

   I just found out I can use OpenAI's GPT-6 Luna for free on Duck.ai without an account. Help me test it with three everyday tasks: [task 1], [task 2], [task 3]. For each one, write the exact message I should type and tell me what a good answer looks like.
