Google and Meta race to build personal AI agents as Anthropic and OpenAI pull further ahead

Google is testing Remy, a personal AI agent inside Gemini, while winding down Project Mariner.

Meta is building Hatch and an Instagram shopping agent, aiming to catch up in personal AI assistants.

Anthropic, OpenAI, and Microsoft currently have more advanced or market-ready agent products.

The shift is moving from browser-demo agents to assistants embedded in productivity and shopping apps.
