wordcell vs ontology-atlas
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.; ontology-atlas: Ontology Atlas helps you understand what your codebase builds, why it is structured that way and what a change will affect. It uses one shared Markdown ontology for humans and coding agents, visualized for people.
