The 3 Best AI Personal Assistants

Comparison — by Mahmoud Zalt

The 3 best AI personal assistants compared: Sistava, OpenClaw, and Claude Cowork. Strengths, who each is for, and links to try each one.

AI personal assistants now range from local-first open-source tools to desktop agents that control your screen. They differ sharply on privacy, setup, and how much real work they own. This short list ranks three.

Sistava leads because its assistant, Alice, is part of a workforce: a personal assistant that can also hand work to specialist AI employees. Each option links to its site and a full breakdown.

Sistava gives you Alice, a personal AI assistant for everyday work, backed by a full workforce. She helps you write, plan, and research like any assistant, but she can also delegate to specialist AI employees, so a request can turn into real work getting done, not just an answer.
