AI Agents & Assistants.

Software that acts on your behalf — collaboration, travel, and multi-agent play.

A set of AI-agent products built by Liu Wei: systems that reason, remember, and act for you. From a trust layer that finds credible collaborators to a voice-first travel companion that plans and sees, these are agents you can actually use today — each on its own domain.

Plaza

FAQ

What are the best AI agent apps to try in 2026?

Two production-ready ones from this studio: Plaza (a trust layer that matches you with credible collaborators using GitHub proof-of-work and LinkedIn verification) and HipiMind (a voice-first AI travel companion that plans, narrates, and provides real-time visual assistance).

What is a "trust layer" AI agent?

Plaza is a trust layer: instead of an open feed, it verifies each person (GitHub + LinkedIn), scores compatibility, and gives every match a human-readable reason with its evidence — so collaboration starts from verified trust rather than cold outreach.

Are these AI agents free to try?

Yes — each links to its own live site where you can try it. Plaza is at polyagent.club and HipiMind at hipimind.com.
