Dropstone 3

The first multiplayer AI code editor. Now with Share Chat.

2026-02-09

Product Introduction

  1. Definition: Dropstone 3 is a multiplayer AI workspace for collaborative software development, combining human teams with autonomous AI agents in real-time. It falls under the technical category of AI-augmented development environments, leveraging proprietary recursive reasoning models and swarm intelligence.
  2. Core Value Proposition: It eliminates the "70% problem" in AI-assisted development by enabling seamless collaboration between stakeholders (developers, business owners, AI agents) within a unified workspace with infinite context retention, ensuring production-ready code without rebuilds or security gaps.

Main Features

  1. Multiplayer AI Chat with Persistent Memory

    • How it works: All team members share a single AI instance with infinite context via the D3 Engine. When a product manager requests a feature, developers immediately see the context, and AI agents retain project history indefinitely (e.g., Day 1 decisions applied on Day 100).
    • Technologies: Claude 4.5 Sonnet, DeepSeek R1, and proprietary D3 Engine for contextual memory storage.
  2. Background Swarms & Adversarial Verification

    • How it works: Up to 25 parallel AI agents autonomously explore solutions, test for bugs/security flaws (L1-L4 verification), and validate edge cases before delivering pre-verified code.
    • Technologies: Recursive swarm architecture with sandboxed testing environments and impact analysis engines.
  3. Role-Based Views & Share Chat

    • How it works: Generates shareable links with role-specific interfaces:
      • Business View: Plain-English chat and app previews (no code).
      • Developer View: Full VS Code-compatible editor with git/terminal.
      • AI Agent View: Real-time activity logs of agent modifications.
    • Technologies: Real-time synchronization protocol inspired by Figma’s collaborative framework.

Problems Solved

  1. Pain Point: AI tools (e.g., Replit, Lovable) stall at 70% completion due to bugs, security flaws, or complex features requiring human intervention.
  2. Target Audience:
    • Business Owners/PMs: Describe features in plain English without coding.
    • Developers: Review and refine AI-generated code in real-time.
    • Engineering Teams: Coordinate AI agents for scalable production hardening.
  3. Use Cases:
    • Fixing production bugs collaboratively while business owners watch.
    • Adding Stripe payments using existing auth sessions (no redundant logins).
    • Generating unit tests via background swarms during feature development.

Unique Advantages

  1. Differentiation:
    • Vs. Cursor/Claude Code: Single-player tools lack shared context and persistent memory.
    • Vs. Replit/Lovable: Solves the "70% wall" by embedding human developers to handle AI limitations in real-time.
  2. Key Innovation:
    • D3 Engine: Enables infinite context windows for long-term project continuity.
    • Recursive Swarms: Original research in parallel agent exploration with L1-L4 adversarial verification.

Frequently Asked Questions (FAQ)

  1. How does Dropstone 3 handle code security?
    Background agents run L1-L4 adversarial verification in sandboxed environments, pre-scanning all code for vulnerabilities before human review.
  2. Can non-technical users collaborate effectively in Dropstone 3?
    Yes, the Business View hides code complexity, allowing product owners to request features via chat while seeing live app previews.
  3. What makes Dropstone 3’s context “infinite”?
    The proprietary D3 Engine compresses and retrieves project history dynamically, retaining all prior decisions without context window limitations.
  4. How many AI agents can work simultaneously?
    Pro plans include 10 agents; Team plans support 25 parallel agents for swarm-based problem-solving.
  5. Is Dropstone 3 suitable for enterprise use?
    Yes, with SSO/SAML integration, audit logging, and pooled team credits for scalable AI-assisted development.
