## What is Delta?

Delta is a platform where software developers can collaborate with AI agents. It combines coding and discussion processes in one place. Currently in private beta, the platform allows developers to see the full context of how code was created. This offers a different experience from traditional IDEs, focusing on collaborative workflows.

## The Role of DeltaDB

DeltaDB is the database system powering the platform. It synchronizes conversations and code changes in real-time. Compatible with existing git repositories, it records every edit and discussion between commits. Team members who don't use Delta still see a standard git repo, maintaining compatibility with existing workflows.

## AI Integration

Delta works with third-party AI tools like Claude Code. Sessions sync to Delta threads even when working in terminals. Team members can observe conversation and code evolution. The platform shows full AI-generated changes without truncating diffs or transcripts, providing complete visibility into agent activity.

## Collaboration Features

The platform allows comments on any line of code, with annotations updating as code changes. Threads start private and can be shared via browser without installation. The web interface, built with WebAssembly and WebGL, replicates the desktop experience precisely. This ensures consistent collaboration regardless of access method.

## Design Philosophy

Delta builds on Zed editor's performance-oriented approach but was developed as a new application. The team chose this path to create a collaboration-first experience rather than adding features to an existing editor. The interface centers conversations rather than traditional editing, reflecting how software development actually happens in teams.

## Preserving Code Context

Delta captures not just what code does but why it was written that way. Future team members can review decision history and rationale. This prevents knowledge loss in large projects. Developers don't need to reconstruct intent from diffs - they can directly ask agents for explanations within the context of the original discussion.

## Multiplayer Support

DeltaDB enables multiplayer functionality even in cloud environments. Agents continue working after laptops are closed. Each participant maintains a local copy of code, with changes synchronized in real-time. This creates a persistent collaboration space that isn't tied to individual devices or sessions.

## The Future of Software Development

Delta has potential to fundamentally change software development processes. Unlike traditional commit-based systems, it offers continuous collaboration. The private beta will shape its evolution based on user feedback. While currently a standalone application, integration with the Zed editor is planned for the future.
