projectmem vs Vault-Agent-Memory

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.; Vault-Agent-Memory: Vault Agent Memory provides a governed, shared memory layer for AI agents, helping them manage what to remember, who can access it, and ensure its accuracy and relevance. It solves common agent memory failures like forgetting bug fixes, misprioritizing old information, and uncontrolled shared memory.

Features

projectmem logoprojectmem
01Pre-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.

01Governed shared memory for multiple AI agents.
02Lifecycle management for memory, including review, promotion, and temporal boundaries.
03Access control and audit trails through governance metadata.
04Local-first architecture with optional self-hosted or cloud backends.
