Context-Engine vs engram-rs

Context-Engine: Context-Engine is an open-core, self-improving code search tool that integrates with AI coding assistants. It allows developers to search their codebase, get answers with citations, and enhances AI agents' ability to explore code using its MCP tools.; engram-rs: engram-rs is a memory engine for AI agents that organizes knowledge along two axes: time (three-layer decay & promotion) and space (self-organizing topic tree). It intelligently promotes important memories, fades noise, and automatically clusters related knowledge, providing a more effective alternative to flat memory stores.
