What It Is

stateful is a shared AI planning tool for collaborative work, with its core assistant called Pango. Instead of treating AI as a one-person chatbot, it places AI inside a shared Space where friends, families, or small teams can discuss things like trips, moving, renovations, budgets, weddings, and team migrations, while continuously turning those discussions into plans.

Core Capabilities

Pango’s main focus is “turning chat into structure.” It can extract prices, dates, options, and constraints from group conversations, then generate or maintain typed artifacts such as itineraries, budgets, places, packing lists, materials lists, decision logs, and timelines. Its memory system is relatively transparent: users can view, edit, and delete memories; personal memories belong to individuals, while group memories require shared confirmation. It can also identify pending items, send timely reminders, and generate a traceable timeline. On the model side, the website only says it uses smart-routed AI: lightweight tasks go to faster models, while deeper planning, document reading, and plan reshuffling are handled by more capable models. Specific model names are not disclosed.

Pricing and Quotas

The free plan is not a short-term trial. It supports the full product, Unlimited Spaces, 500 AI credits per month, and does not require a credit card. Once the quota is reached, it does not lock your plans; instead, it switches to a lightweight model so you can keep chatting. Pro costs $11.99/month or $99/year and includes 3,000 AI turns per month, the best models, shared quota across Spaces, and photo and file uploads. A Space created by a Pro user can give other members in the group a Pro experience. The For Work enterprise plan has not officially launched yet. It will use custom pricing and include an organization-level quota pool, SSO, audit features, an admin console, SLA, and DPA.

Pros and Cons

Its strengths are its focused use cases and clear collaboration logic, making it well suited for turning messy group chats into executable plans. The free entry barrier is low, and Pro’s group-sharing mechanism is also fairly friendly. The downsides are that it is still an early-stage product, and the website does not clarify Chinese-language support, underlying models, payment methods, or accessibility from mainland China. The free plan is best suited to two people per Space, and complex artifact updates will consume more credits.

Who It’s For and Access from China

stateful is suitable for families, friends, and small project teams who frequently plan things together, especially long-running, decision-heavy scenarios such as travel, home renovation, moving, and event preparation. Its accessibility from mainland China is unknown, and payment methods have not been disclosed. If access, payment, or Chinese-language experience is limited, alternatives such as Notion AI, ChatGPT Projects, 飞书, 钉钉 AI, and 腾讯文档 may be worth considering.
