What is Dropstone 3?

Editorial review
Dropstone is a collaborative AI workspace designed to streamline software development by integrating business owners, developers, and AI agents into a single, real-time environment. It allows non-technical users to describe features in natural language, while AI agents build the code, and developers review and refine it. This platform aims to solve the "70% problem" often encountered with other AI tools, where AI can initiate a project but struggles with complex features, bugs, or production-readiness, by ensuring a developer is always present in the workspace to handle challenges. The product features a unique "multiplayer AI chat" where all team members interact with a single AI that maintains infinite context, remembering past decisions and conversations across sessions. It offers role-based views, adapting the interface for business owners (chat and live preview) and developers (full VS Code-compatible editor, terminal, git integration). Dropstone also leverages background AI agents that explore multiple solutions, test for bugs and security flaws in parallel, and present only pre-verified, optimal solutions, significantly accelerating the development process and ensuring code quality.
