Verdict: DeepSeek's AI models are technically impressive but the service stores all data on servers in China, subject to Chinese government access laws. Users should assume all conversations are accessible to Chinese authorities.
DeepSeek is a Chinese AI company that released competitive open-source and API-based language models. Its chatbot gained massive popularity in 2025, but its Chinese ownership raises significant data privacy concerns similar to TikTok.
