AI Agents

Personal AI agents compared: Claude Duet vs Dot vs Gemini Spark vs Grok Bot vs Muse (October 2026)

One table comparing eight personal AI agents: hosted Claude Duet, Dot, Gemini Spark, Grok Bot, Instinct and Muse, plus open-source, self-hosted Hermes Agent and OpenClaw. Every cell links to an official page; anything the vendor doesn’t publish says “Not disclosed”.

Productivity agents sell proven ROI to a narrow paying base; secretary agents sell back time to everyone else, monetised by transactions, not subscriptions.
