【#Tech24H】Recently, Anthropic released a mobile app named Claude Duet. Each morning, it sends users a briefing highlighting priority items from emails, calendars and linked accounts. If it spots an overdue bill, it can draft a reminder email, and settle the payment directly upon user approval. This is only one of a wave of comparable products launched by global tech giants over the past month. In September, Meta rolled out its personal agent Muse. Shortly afterwards, Microsoft unveiled its next-generation Copilot, describing it as "an assistant that keeps working even when you're off work." Late in September, OpenAI made dots available, a product capable of sending messages and placing calls on users’ behalf. At the end of October, Tencent WorkBuddy released Buddy One, a collaborative agent linking documents, meetings and cloud storage. These offerings fall under the same category: personal agents. As mobile apps actively update users and execute tasks, AI is evolving beyond chatbots into proactive work assistants, ushering in a new working paradigm.
