Dropstone is a multiplayer AI coding workspace where business owners, developers, and AI agents collaborate in real-time. It solves the '70% problem' where other AI tools stall by providing a shared AI with infinite context, role-based views, and background agents that test and verify code before delivery, ensuring projects are production-ready.

How to use Dropstone 3?
Teams start a shared workspace. Business owners describe features in plain English chat. The shared AI, with memory of all conversations, generates and modifies code. Developers review the AI's work in a full code editor. Background agents autonomously explore solutions, test for bugs and security flaws, and present only the best, verified result. Everyone sees a live preview of the app being built.
Dropstone 3 's Core Features
Multiplayer AI Chat: A single, shared AI instance that your entire team interacts with in real-time. It maintains infinite context, remembering decisions from Day 1 on Day 100, so when one member requests a feature, another can build on it without repetition.
Role-Based Views: Adapts the interface for different team members. Business owners see a chat and live preview without code. Developers get a full VS Code-compatible editor, terminal, and git integration. Everyone stays in sync without confusion.
Background Agent Swarm: An AI workforce that explores multiple solution paths in parallel while your team focuses on strategy. Agents pre-validate code for bugs, security flaws, and edge cases, delivering only the best, tested solution.
Real-Time Collaboration & Sharing: Generate a shareable link to any workspace. Control viewer and editor access. Collaborate on files with live editing previews, enabling seamless teamwork between technical and non-technical members.
Production-Ready Code Assurance: Addresses the '70% problem' by combining AI generation with human developer oversight. Developers are integrated into the workspace to fix bugs, handle complex features, and harden code for scale, preventing project stalls.
Advanced Model & Compute Options: Supports local models (Ollama) and frontier models like Claude 4.5 and GPT 5.2. Plans include features like Scout swarm exploration, adversarial verification (L1-L4), and impact analysis for robust code generation.
Enterprise Governance & Security: For teams, includes SSO/SAML integration, advanced audit logging, and sandboxed verification. The platform has built-in safety alignment to prevent malicious code generation and ensures commercial compliance.
Dropstone 3 's Use Cases
Startup Founders & Product Managers can describe app features in plain English and watch a live, functional prototype get built by AI, with a developer on hand to ensure it's viable, accelerating MVP development dramatically.
Software Engineering Teams use the shared AI workspace to maintain context across complex projects. Junior developers can learn from AI-generated patterns, while seniors review and refine code, all collaborating in real-time to ship faster.
Agencies & Freelancers working with non-technical clients can share a workspace link. Clients see progress in a business-friendly chat view, while the developer works in the code view, streamlining communication and approval cycles.
Educational Institutions & Bootcamps provide students with a hands-on environment where they can describe projects, see AI build them, and then dissect and learn from the generated code, bridging theory and practice effectively.
Enterprises with Legacy Systems can use the AI's exploration agents to test multiple modernization or integration paths safely. Developers review the proposed solutions, mitigating risk and accelerating digital transformation projects.
