memex vs context-mode
memex: memex provides persistent memory for AI coding agents using atomic knowledge cards with bidirectional links. It stores insights from each session and recalls relevant cards before starting new tasks, enabling agents to build on previous knowledge. No vector database or embeddings needed—just markdown files.; context-mode: Every tool call in an MCP (Model-Controller-Program) environment dumps raw data into the context window, quickly consuming space and causing the agent to lose track of ongoing tasks. Context Mode is an MCP server that tackles this by sandboxing tool outputs to significantly reduce context usage, tracking session events in SQLite for continuity, and promoting 'think in code' to minimize data processing within the LLM.

02Atomic knowledge cards with bidirectional links
03Cross-platform sharing across editors
04No vector database or embeddings required
05Visual timeline and graph view UI
context-mode01Context Saving: Sandbox tools keep raw data out of the context window, achieving up to 98% reduction.
02Session Continuity: Tracks every file edit, git operation, task, and user decision in SQLite for seamless session resume.
03Think in Code: Promotes LLMs to program analysis, not compute it, saving 100x context by logging only results.
04Batch Execution & Search: Run multiple commands/queries in one call with tools like `ctx_batch_execute`.
05Advanced Knowledge Base: Uses SQLite FTS5 with BM25 ranking, smart snippets, and TTL cache for efficient information retrieval.
