remem vs projectmem

remem: `remem` is a local-first memory solution for AI coding agents like Claude Code and OpenAI Codex, preventing repetitive explanations by automatically capturing and injecting project context. It distills, searches, and stores project decisions, bug fixes, and preferences locally using SQLite, accessible via CLI, hooks, and a REST API.; 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

remem logoremem
01Automatic memory capture and injection for coding agents.
02Searchable history of project decisions, bug fixes, and rationale.
03Local-first memory storage with SQLite and SQLCipher encryption.
04Accessible via CLI, coding agent hooks, MCP tools, and REST API.
05Single Rust binary with no external database dependencies.
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.
