Pex — Persistent Memory for AI Agents

Pex offers a special kind of memory for AI agents, helping them remember and share information. Normally, AI agents forget things once a conversation ends. Pex makes sure that the knowledge they gain stays with them and can be used again later, even across different conversations, tools, or teams.

Benefits

Pex gives AI agents a lasting memory. This memory is organized so agents can easily find and reuse what they have learned. It allows different AI agents, especially those using MCP, to access the same stored information. This means agents don't have to start from scratch every time they interact.

Use Cases

This technology is useful for many tasks. Engineers can use it to see how changes in one part of a system might affect other parts. It helps in breaking down large features into smaller, manageable steps. It can also show what needs to be in place before a certain process can start. For new team members, Pex can provide a complete understanding of a project's codebase right away, making onboarding much faster.

Vibes

Pex is designed to help engineering leads map out how different services and APIs connect. Product leaders can use it to keep track of important goals and processes, ensuring AI agents align with business needs. Founding engineers can speed up their work because the shared knowledge stays consistent even when switching between tasks or team members. Technical writers can keep their documentation up to date with a reliable source of information.

Additional Information

Pex uses tools like a Visual Graph Editor to help model information and a Semantic Search to find related details. The data is stored securely in PostgreSQL. An API allows for quick searches, providing answers in less than 300 milliseconds. Features for real-time teamwork between multiple agents are planned for the future.
