Score: 5.7/10 (Innovation: 6, Technical: 5, Documentation: 6, Utility: 6)

Stele is a shared memory and knowledge graph service for AI coding agents, letting multiple tools like Claude Code, Cursor, and Copilot read and write a common project record. It focuses on maintaining truth over time by retiring reversed decisions and flagging drift, which addresses a gap left by plain files or per-tool memory. The hosted product targets teams using multiple AI agents, with an open self-hosted version planned.

Target audience: backend devs, ai engineers, devops, engineering teams using multiple AI coding assistants
