Berges AI vs Duck.ai
Duck.ai hides who you are from big-lab models. Berges AI runs open-weights models and changes how they answer. Different ideas of private, both honest.
Duck.ai is DuckDuckGo's answer to AI privacy: you chat with models from OpenAI, Anthropic, Mistral, and open-weights hosts through DuckDuckGo's proxy, with no account, so the model provider never sees who you are. Providers have agreed not to train on the traffic and to delete it within a set period. Free to use, with paid tiers for frontier models.
Berges AI takes the other road: open-weights reasoning models only, conversations stored encrypted so you can return to them, and a product layer that cuts filler. Anonymity is not something we claim. Control over the output is.

How they're different
Anonymity vs ownership
Duck.ai's core promise is that the model provider cannot tell who you are. Ours is that your conversations belong to you: encrypted at rest, never trained on, deletable in one click, and there whenever you come back. If you never want a chat to exist after you close the tab, Duck.ai is built for that. If you want to keep and revisit your thinking, that is us.
Closed frontier models vs open weights
Duck.ai gives you GPT and Claude, anonymized. Berges AI runs only open-weights models, which anyone can audit and host. On the hardest questions the frontier closed models are still ahead, and Duck.ai is a good way to reach them without an account. For everyday thinking the open models are close, and we shape how they answer.
Raw model vs shaped output
Duck.ai passes your message to the model and returns what it says, in the style each provider chose. Berges AI runs every reply through rules that remove the filler and pipelines that set the job. If the tone of AI answers bothers you, that is the difference you will feel first.
Things people ask about Berges AI vs Duck.ai
Is Duck.ai private?
In the sense that matters to it, yes: the providers see DuckDuckGo, not you, and have agreed not to train on the traffic. Your message still reaches those providers in plain text to be answered. That is true of every chat product, ours included.
Why pay for Berges AI when Duck.ai is free?
For saved, encrypted conversations across devices, a reasoning model on every turn that you pick, pipelines, and terse output. If you only need occasional anonymous questions, Duck.ai is the sensible free choice.
Can I use both?
Yes. Duck.ai for one-off anonymous questions to frontier models; Berges AI for ongoing work you want to keep and for answers without the padding.
