DuckDuckGo, known for its focus on online privacy, is launching two new subscription services called Duck.ai Plus and Duck.ai Pro. These services grant users access to advanced artificial intelligence (AI) models such as Claude Opus 4.8 and GPT-5.6 Sol, with prices set at 9.99 and 19.99 euros per month, respectively. The goal is to provide users with powerful AI tools while maintaining strong privacy protections. The Plus plan includes the four existing privacy features already offered by DuckDuckGo, while the Pro plan adds access to more advanced models, increased reasoning capabilities, and doubled usage limits. Users who commit to an annual subscription receive a 16% discount. It is important to note that these subscriptions are not solely for AI access; they are part of broader privacy packages that include a no-logs virtual private network (VPN) and identity protection tools. Unlike some competitors, Duck.ai does not host AI models internally. Instead, it acts as an anonymization layer, routing requests to models owned by other companies. The free version of Duck.ai gives access to several models, including Claude 4.5 Haiku, Mistral Small 4, and various GPT models from OpenAI. The Plus plan adds access to GPT-5.4 and Claude Sonnet 4.6, while the Pro plan includes Claude Opus 4.8 and a second model, GPT-5.6 Sol, which is exclusive to Pro users. In comparison, Perplexity, another AI service, offers its most advanced models through its Max subscription, which costs around 200 dollars per month. Duck.ai Pro, however, offers similar capabilities at a fraction of the cost, though Perplexity is noted for being more responsive and using newer models such as GPT-6 Sol and Claude Opus 5.5. DuckDuckGo emphasizes that it removes user-identifying metadata, such as IP addresses, before sending requests to model providers. This means that conversations sent through Duck.ai appear to originate from DuckDuckGo's infrastructure rather than the user's device. The company also has agreements with model providers to delete conversations after responses are generated, prohibit using them to train models, and prevent sharing them with third parties for commercial purposes. With Tinfoil, a specialized provider of confidential computing, DuckDuckGo ensures that certain models like gpt-oss-120b and Gemma 4 31B are processed in hardware-encrypted environments, ensuring that even Tinfoil cannot access the content of exchanges. However, files and images sent to Duck.ai are not encrypted and are analyzed for child sexual abuse material (CSAM) by external providers. Such flagged content is stored and reported to authorities, while all other files are deleted. The free version of Duck.ai does not require an account, and conversation history is stored locally on the user's device rather than on DuckDuckGo's servers. However, users can enable synchronization across multiple devices. It is important to note that Duck.ai is subject to U.S. law, including the Cloud Act, which allows government access to user data. For true anonymity, users are advised to avoid syncing data and to avoid using credit cards for paid subscriptions. Hands-on testing of Duck.ai Pro showed that it provides balanced responses to general knowledge questions, accurate current event information, and high-quality image generation and editing using GPT Images 2.0 from OpenAI. While Duck.ai Pro is the most affordable way to access Claude Opus 4.8, it lacks features found in other AI platforms. Unlike services such as Lumo Plus or Le Chat Pro, which offer standalone AI subscriptions, Duck.ai and Euria bundle AI access with privacy tools. Duck.ai remains a chat interface with limited organizational features, such as a local conversation history and the ability to pin up to five recent chats. There is no persistent memory across sessions, no customizable assistants, and no development environment. Additionally, no public API is available, making it impossible to integrate Claude Opus 4.8 or GPT-5.6 Sol into external workflows or third-party applications. As a result, Duck.ai functions as an anonymized gateway to AI models rather than a full work environment.
