Two experiences built on the same research foundation
Dropstone Editor
Write, debug, and ship production code with
AI-powered autocomplete and multiplayer editing.
Dropstone Agents
Configure, deploy and monitor autonomous
AI agents that build features end-to-end.
Build production-ready software with AI-powered autocomplete, intelligent code review, and real-time multiplayer editing. From your first line of code to deployment, Dropstone handles the entire workflow in a single unified workspace.
AI-powered coding
Intelligent autocomplete, inline suggestions, and natural language code generation built on cutting-edge research.
Update docker-compose.yml with the new Stripe v3 env vars and add a health check endpoint for the payment service container
Now run the integration test suite against the staging Stripe keys and verify webhook signature validation
Multiplayer collaboration
Real-time editing with teammates and AI agents in the same workspace — review, discuss, and ship code together.
Dropstone Memory
Context that persists across every session
Persistent Knowledge Graph
Dropstone remembers your codebase patterns, architecture decisions, and team preferences — automatically retrieved in every future conversation.
Auto-capture
Learns from every interaction without manual setup
Cross-session
Memories persist and improve across all conversations
Team-shared
Share context across your entire engineering team
Team uses pnpm with Vercel preview deployments on every PR. Staging branch auto-deploys.
Cognitive Architecture
The world's first AI IDE that builds itself
Powered by cognitive long-term continual learning that persists across every session. Your AI doesn't just respond — it remembers, adapts, and evolves, creating an effectively unlimited context window that grows smarter with every interaction.
Continual Learning
Neural pathways strengthen with every codebase interaction
Unlimited Context
No token limits — memory grows infinitely across sessions
Self-Evolving
Autonomously refines its understanding of your architecture
MCP Integrations
The world's first AI-native MCP platform.
Figma MCP
Your AI design partner, directly on canvas.
Dropstone connects to Figma through MCP and operates as a collaborative AI designer that works directly on your canvas. Select any layer, describe your intent in natural language, and watch edits apply in real time. The first production-grade AI designer published at global scale.
Created a professional Hero Component in Figma following Linear.app design principles. • Design Features: Clean, minimal aesthetic with generous white space • Centered layout with clear visual hierarchy...
Windows MCP
Native desktop control. No compromises.
Dropstone interfaces with your desktop through native OS APIs instead of relying solely on screen capture. This results in faster execution, higher accuracy, and significantly fewer errors than any comparable tool. Screenshot-based fallback is still available when needed, but it is rarely required.
Research that redefines
developer-AI interaction
We develop foundational infrastructure for AI-assisted software engineering. Our work spans context-aware code reasoning, autonomous execution, and long-context retrieval, published as open research contributions.
Cognitive Architecture
The world's first AI IDE that builds itself.
Dropstone is engineered on proprietary research in multi-file code reasoning, bounded-latency inference, and autonomous task execution. Each subsystem is designed from first principles to understand software architecture, not approximate it.
D3 Engine
A multi-pass reasoning engine optimized for deep contextual understanding across large codebases with bounded latency.
Horizon Mode
Asynchronous agent execution framework enabling parallel task decomposition with deterministic conflict resolution.
Long-Context Retrieval
Solved degradation in retrieval accuracy over extended context windows, achieving consistent precision at 128K+ tokens.
Advancing research beyond code completion into context engineering, autonomous agents, and more.
