Software development is becoming a collaboration between developers and AI systems.

Most AI developer tools operate on prompts and static snapshots of code. But real software development happens inside large, evolving codebases that change continuously through edits, refactors, discussions, and collaboration.

We are building AI systems that operate inside that environment.

Zed today is a code editor built from scratch in Rust with GPU acceleration and real-time multiplayer collaboration. Every keystroke and edit can be shared instantly between collaborators, creating a shared workspace where developers and increasingly AI systems can work together.

We are also building DeltaDB, a system that records the operational history of software development. It captures edits, discussions, and AI interactions as they happen. This creates a foundation for AI systems that can reason not just about code, but about how that code evolves over time.

Much of this wo...
