wordcell vs xerj

wordcell: Wordcell is a Markdown knowledge base and local MCP memory server for coding agents such as Claude Code, Codex and Cursor. It keeps decisions, plans and sources as Markdown beside your code, and agents find them by exact words, by meaning with an optional local model, or from the file they are about to change.; xerj: XERJ is a single Rust binary that auto-indexes any folder (code, docs, logs, CSV, PDFs) for BM25, vector and hybrid search behind an Elasticsearch-compatible API. It plugs into Claude Code, Cursor and other MCP clients so agents retrieve exact passages instead of reading files one by one.
