Anthropic stepping directly into the consumer agent arena marks a shift from safety-first lab to full-stack contender, and the agent market now effectively has three heavyweight horses. The 'research preview' framing is classic Anthropic caution, but shipping standalone iOS and Android apps shows they want agents as daily drivers, not developer toys. Targeting professionals and small businesses is a shrewd wedge — it sidesteps the mass chatbot war where OpenAI and Meta own distribution. The real question is whether Claude's reputation for reliability converts into agent trust, since agents fail in messier, more visible ways than chatbots. In our view the launch itself matters less than retention: if Duet handles multi-step work without hand-holding, this is a genuine three-way race; if not, it's table stakes in a crowded rush.
