The only editor that codes, tests, and debugs in the background.

Dropstone is deployed as a fully compatible fork of VS Code. You get the zero-learning-curve interface you expect, powered by a D3 Runtime that provides infinite context retention and adaptive learning from your natural language interactions.
Dropstone learns from your chats. Tell it your coding preferences once—like "always use arrow functions"—and it will remember them forever. No more redundant prompting.
Continuously learns from interaction.
Instantly applies rules to new chats.
Dropstone utilizes a vector-based latent memory system to retain infinite context without token limits.
It remembers your entire codebase, documentation, and past conversations. Never lose context again.
Codebase, docs, and full history.
Zero data loss across sessions.

We are truly extending the context window where We had to rethink how the model manages memory. 128k isn't a hard limit of intelligence; it's a limit of efficiency. We went back to the papers to virtualize the window and fix the retrieval bottleneck.

Memory Virtualization: Dynamic context management.
Standard AI forgets context as projects get large. Dropstone breaks complex features into small tasks and solves them autonomously.
Deterministic Decoupling. The D3 Engine separates state from probabilistic generation, routing tasks to optimized Scout Swarms.
Standard AI forgets things when the conversation gets too long. Dropstone separates 'Active Memory' (what you're doing now) from 'Long-term Storage' (history), allowing it to work on massive tasks for 24+ hours without getting confused.
Dropstone replaces standard generation with a rigorous peer-review loop. Agents must pass a verification step where other agents review their code in real-time. If the logic fails the review, it is rejected before you ever see it.
We treat compute as a liquid asset. The system instantiates 10,000 ephemeral "Scout" agents to explore divergent solution trees. This allows the runtime to test low-probability strategies (P < 0.05) that linear models discard.
Most AI guesses the next word. Horizon Mode explores thousands of potential solutions in the background, testing them for bugs and logic errors before showing you the perfect one.
The system deploys up to 10,000 isolated "Scout" agents utilizing optimized Small Language Models (SLMs). These agents explore "low-probability" solution vectors
(P < 0.05) at near-zero marginal cost.
When a Scout hits a dead end, it broadcasts a "Failure Vector" to the shared workspace. The swarm utilizes this Negative Knowledge to globally prune invalid logic branches in real-time.
Upon identifying a candidate solution with high confidence (P > 0.85), the state is Promoted. The D3 Engine injects the relevant context into a Frontier Model for high-fidelity refinement.
The resulting code is not a generation—it is the surviving winner of
10,000 parallel experiments conducted within the D3 search space.
Core architectural components designed for high-throughput engineering environments where latency and reasoning depth coexist.
Intelligently assigns tasks: uses fast models for simple code and deep reasoning models for complex architecture.
Instantly shares learned mistakes across the swarm so no agent repeats an error.
Rigid separation of memory manifolds (Episodic, Sequential, Associative, Procedural) to prevent drift.
Only solutions that are 85%+ verified are saved to long-term memory.
Dropstone keeps your team in perfect sync. It tracks the history of every decision and code change, allowing you to review deep reasoning trails or share context snapshots with a single click.
Replay the context construction to see exactly how the AI reached its conclusion.
Granular permissions ensure junior devs only see approved architecture patterns.

The system doesn't guess. It runs thousands of simulations in the background. If an agent's output varies too much (entropy), it is flagged as a hallucination and pruned instantly, forcing the swarm to agree on the single correct solution.

Transform isolated work into shared intelligence. Unlike standard tools, when Dropstone learns a mistake from one developer, it instantly updates the entire team's context so no one repeats that error again.
Agents can branch from any peer's causal graph without re-computing the context window.

Autonomous agents require a Deterministic Envelope. We utilize a multi-stage consensus protocol (Cstack) that verifies code execution in ephemeral, network-isolated sandboxes with kernel-level syscall filtering.
All unverified logic is detained in network-gapped microVMs. Agents must pass "Property-Based Testing" where adversarial nodes attempt to inject edge-case failures.
We monitor Semantic Entropy (Perplexity Spikes). If the PPL variance exceeds the safe threshold, the branch is immediately pruned via the Flash Protocol.
Visualizing the double-gate validation process. Artifacts are subjected to adversarial sandboxing before passing entropy thresholds.
Traditional software engineering hits a Linearity Barrier. As a system grows larger, it becomes harder for humans to maintain, causing progress to stall.
Dropstone removes this barrier. By using Recursive Swarms to write the implementation details, velocity actually increases as the system gets more complex.
Comparing Human limits against Recursive AI
Describe your goal in plain English. Dropstone understands your entire codebase deeply enough to refactor legacy code, spot architectural issues, and implement new features without breaking existing logic.
Powerful, yet bounded. We prioritize Prompt-Guided Execution. The agent amplifies intent; it does not hallucinate features.
Non-deterministic output. System outperforms industry benchmarks by orders of magnitude, yet human oversight remains required for commit ratification.
