Google Gemini Spark Review — A 24/7 Personal AI Agent That Never Sleeps

Google Gemini Spark is a 24/7 personal AI agent announced at Google I/O 2026 that runs on dedicated Google Cloud VMs, stays active when your devices are off, and accepts task delegation via a dedicated Gmail address. At launch it integrates natively with Gmail, Docs, Drive, Calendar, Sheets, Slides, YouTube, and Maps, with MCP-based third-party integrations (GitHub, Notion, Slack) arriving over the summer. Currently US-only for Google AI Ultra subscribers ($100/month). We cover what Spark is, how it works, its privacy concerns, and whether it's ready to trust with your digital life.
