About DeepSeek
DeepSeek is an AI assistant created by DeepSeek. It is available through the official DeepSeek website and official mobile apps, and it is used for conversational help, analysis, writing, coding assistance, and reasoning-focused explanations. The official app was announced in January 2025 as a free assistant, but the current feature set, model choices, service availability, and account requirements can change over time.
