The Bottom Line
Most AI assistants in 2026 are still glorified chatbots — you open them, ask a question, get an answer, and close them.
OpenClaw is the only option that combines always-on operation, messaging app integration, persistent memory, and proactive behavior. It's the closest thing to having an actual personal assistant — one that remembers your life, works while you sleep, and costs less than a Netflix subscription.
