Summary

In late February 2026, Perplexity released its "Personal Computer," an autonomous AI system designed to function as a digital worker capable of executing multi-step workflows. This product is positioned as a potential catalyst for the "Autonomous AI Era," supporting the rise of one-person companies and solopreneurs. Early 2026 reviews indicate Perplexity Computer is powerful but high-friction, primarily due to cost and consistency issues, making it ideal for AI power users with substantial resources or medium-sized enterprises with specific needs. The article highlights the broader trend of autonomous AI tools like Claude Cowork, Microsoft's Critique, Claude Code, Cursor, and Manus AI, and questions the future capabilities and return on investment for such systems, especially given the context of significant AI infrastructure investments.

Key takeaway

For AI Product Managers evaluating new agentic AI tools, Perplexity Computer represents a significant step towards autonomous digital workers. You should assess its high power against its reported high friction, particularly regarding cost and consistency, to determine if it aligns with your enterprise's specific needs or if alternative solutions like Claude Cowork or Cursor offer a better balance for your target users.
