What is Dropstone 3?
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.
Available on: Web, Windows

Dropstone 3 FAQ
How does Dropstone's 'Infinite Context' feature manage token consumption for large codebases?
Dropstone optimizes token consumption at the infrastructure level, reducing per-request usage by over 58% compared to standard tools. This efficiency allows for unlimited tokens with generous rate limits, enabling the handling of 100K+ line codebases with the same token efficiency as a single-file edit.
What is the function of the 'PIP Mode' interface in Dropstone?
PIP Mode provides a compact floating interface for orchestrating Multi-Agent Control Planes (MCPs), coordinating multi-agent workflows, and controlling the sequence of execution across an entire stack. It allows users to trigger and monitor MCP servers and define operational order without leaving their current window.
How does Dropstone's integration with Figma MCP enhance design collaboration?
Dropstone connects to Figma through its MCP, acting as a collaborative AI designer directly on the canvas. Users can select any layer, describe their intent in natural language, and observe real-time edits, making it a production-grade AI designer for global scale.
What is the 'Cognitive Architecture' and how does it contribute to Dropstone's functionality?
The Cognitive Architecture powers Dropstone's AI IDE with cognitive long-term continual learning that persists across every session. This allows the AI to remember, adapt, and evolve, creating an effectively unlimited context window that grows smarter with every interaction through continual learning and self-evolving capabilities.
What are the key differences in compute capabilities between the 'Pro' and 'Teams' pricing plans?
The 'Pro' plan offers unlimited local and fast models with approximately 750 frontier requests per month, utilizing Horizon Scout swarm exploration. The 'Teams' plan provides pooled team credits with around 2,250 frontier requests per month (3x the Pro plan), incorporating Horizon Flash protocol instant pruning and L3-L4 sandboxed verification.
How does Dropstone's 'Memory' feature improve over time and across team members?
Dropstone's Memory builds a persistent knowledge graph from every interaction without manual setup, learning codebase patterns, architecture decisions, and team preferences. This context persists and improves across all conversations and can be shared across the entire engineering team, ensuring it's always relevant to the current task.
