wenlan vs projectmem
wenlan: Wenlan is a living personal knowledge library for the AI-native age, built by your agents and grounded in its sources. It continuously evolves between sessions, distilling captures into source-cited wiki pages that feed retrieval.; projectmem: projectmem is an open-source, local-first memory and judgment layer for AI coding agents, designed to capture persistent records of project development, including issues, attempts, fixes, and decisions. It aims to make AI experienced, preventing repetition of past failures and significantly reducing token usage by providing distilled context.

Features
wenlan01Trustworthy and source-cited knowledge pages, with hallucination prevention and fact deduplication.
02Self-evolving knowledge base that updates and refines between sessions without manual maintenance.
03Real Git versioning for all memories, pages, and sessions, enabling inspection, diff, and revert.
04Unified local daemon serving context to multiple MCP-compatible AI clients.
05Hybrid retrieval system leveraging vector embeddings, FTS5, and graph context for relevant recall.
projectmem01Pre-Commit Warnings: Warns developers before committing if they're repeating failed approaches, modifying high-churn files, or touching unresolved issues.
02Local-First and 100% Private: All memory and data reside locally in a `.projectmem/` directory with no cloud, accounts, or telemetry.
03Global Dashboard: Provides a unified view of all `pjm init`-ed projects, showing grades, issues, savings, and a 'needs attention' list, aggregated at read-time.
04Code Structure + Judgment: Overlays failure heat from the event log directly onto the codebase's import graph, highlighting files with repeated failed attempts.
05Smart Context Injection & Token Efficiency: Distills raw event logs into compact, AI-readable summaries and provides token-budgeted memory blocks, significantly reducing token cost.

Use Cases
wenlan↳Capture decisions, lessons, and facts from AI agent interactions to build a persistent knowledge base.
↳Maintain continuous, topic-relevant context across multiple AI agent sessions and projects.
↳Distill raw agent captures and existing documents into trustworthy, source-cited wiki pages.
↳Integrate a shared memory and context layer across various AI development environments like Claude Code, Cursor, and VS Code.
projectmem↳Preventing AI agents from repeating past debugging attempts or failed architectural approaches.
↳Improving AI agent efficiency and reducing token costs by providing distilled, context-aware project memory instead of re-reading raw files.
↳Visualizing project development history, including issues, fixes, and decisions, to understand codebase evolution and identify problem areas.
↳Onboarding new developers or bringing AI agents up to speed on a project quickly by injecting pre-existing project knowledge and decisions.
↳Providing a persistent, auditable record of AI agent interactions and learning within a project.
