As answered by people managing Codility and ShardStitch.
ShardStitch's answer:
ShardStitch focuses on recovering the actual project state, not just preserving conversation history. It records verified files, git changes, failed attempts, known constraints, and next steps so coding work can continue after an AI session fails or moves to another tool.
ShardStitch's answer:
ShardStitch is local-first, tool-agnostic, and designed for recovery. It helps developers continue from verified project state across multiple AI coding tools instead of relying on one provider’s chat history or memory system.
ShardStitch's answer:
AI-assisted developers, software engineers, technical leads, and small development teams who use coding agents and need reliable recovery when sessions get stuck, lose context, reach limits, or switch tools.
ShardStitch's answer:
ShardStitch was created around a practical problem: AI coding sessions can make useful progress but still leave developers unsure what changed, what failed, and how to continue. ShardStitch turns that uncertain handoff into a structured, verifiable continuation process.
ShardStitch's answer:
ShardStitch is built around local filesystem and git-state inspection, structured Markdown and JSON recovery packets, deterministic verification, and adapters for supported AI coding tools.
ShardStitch's answer:
ShardStitch is currently used primarily by individual developers, technical practitioners, and small teams experimenting with AI-assisted software development. No enterprise customers are publicly named at this time.
