Obscurify.ai vs Duck.ai
Short answer: Duck.ai is great for quick, free questions: it needs no account, it’s built into DuckDuckGo, and it has signed contracts with its model providers. Obscurify.ai is for when you need more: 200+ models instead of about ten, an API, published limits, uncensored models, Tor, or paying with Monero or Bitcoin in a way that can’t be linked to your account.
Duck.ai and Obscurify.ai are services that act as a privacy barrier for your data when using LLMs. Duck.ai is free and offered by a giant brand. Obscurify.ai is a small and paid service but offers a much larger selection of models. The info about Duck.ai in this review is from DuckDuckGo’s website (links provided below).

Where Duck.ai is the better choice
Duck.ai is free and has a much better free lineup than most: models from OpenAI, Anthropic, and Mistral, plus open models, and you don’t even need an account. It’s baked into DuckDuckGo search and the DuckDuckGo browser, meaning it’s one click away from millions of users.
In terms of privacy contracts, Duck.ai is more advanced. DuckDuckGo has signed agreements with its providers for zero data retention and no training, and they publish the exceptions per provider. Obscurify.ai has the zero-data-retention routes, but depends on the providers’ published policies, without signed agreements. Duck.ai also has two open models running in a TEE, which means the host can’t read these prompts.
Duck.ai also includes voice chat, image generation/editing, encrypted chat sharing and deep browser integration, all of which Obscurify.ai doesn’t offer. Plus the DuckDuckGo subscription comes with a VPN.
Where Obscurify.ai is the better choice
Models. Duck.ai offers about ten models across all plans. Obscurify.ai has 200+, including Gemini, DeepSeek, Qwen and other labs Duck.ai doesn’t carry, and every model has its own page with live prices.
Limits you can plan around. Duck.ai doesn’t publish its limits, for free or paying users. Obscurify.ai publishes the guest limit, and accounts pay per message at listed prices, with usage included on Casual and Pro.
An API. Duck.ai has no API and its terms forbid automated use. Obscurify.ai’s OpenAI-compatible API works on every plan with a positive balance, at the same prices as the chat.
Paying without a card. Duck.ai’s subscription is paid through Apple, Google or Stripe. Obscurify.ai takes Monero, Bitcoin and Lightning through its own BTCPay Server, plus cards, and every payment becomes blind-signed vouchers that can’t be linked to your account.
Uncensored models. Duck.ai’s terms rule out sexual content and regulated advice. Obscurify.ai’s Pro plan includes uncensored models.
Tor and local models. The whole Obscurify.ai site runs as an onion service, and Local Mode runs small models entirely in your browser.
Using both
They’re good partners. Duck.ai is the right choice as your baseline for low-risk queries. Obscurify.ai takes over when Duck.ai reaches its limit, when you need a particular model or an API, or when you want to pay without a card.
