claude-mem
thedotmack
Persistent memory compression plugin that captures what coding agents do in each session and injects relevant context into future sessions.
Key features
- Automatic Session Capture: Five lifecycle hooks (SessionStart, UserPromptSubmit, PostToolUse, Stop, SessionEnd) record tool usage and observations without manual effort.
- AI Memory Compression: Generates semantic summaries of what the agent did so past work is stored compactly.
- Context Injection: Relevant context from previous sessions appears automatically in new sessions.
- Hybrid Search: A SQLite store plus Chroma vector database enables semantic and keyword search across sessions.
- Token-Efficient MCP Tools: A three-layer search, timeline and get_observations workflow filters before fetching details, saving about 10x tokens.
- Worker Service and Web Viewer: A local HTTP API managed by Bun provides a web UI and search endpoints.
- Multi-Host Install: One command installs for Claude Code, OpenCode, T3 Code, Antigravity CLI, OMP and Pi, and a script sets it up on OpenClaw gateways.
- mem-search Skill: Natural-language queries over past work with progressive disclosure of detail.
Best for
- Long-Running Projects: Keeping a coding agent aware of decisions and bugfixes made weeks earlier.
- Session Handoff: Resuming work after a disconnect without re-explaining the codebase.
- Team Agent Workflows: Preserving institutional knowledge across many agent sessions.
- Debug History Lookup: Searching what an agent tried previously on a recurring bug.
- Token Cost Reduction: Pulling only filtered memory details instead of re-reading large context.
- Cross-Agent Memory: Sharing persistent context between different agent hosts.
Unprompt
Polymorph
iPhone and Mac app that measures your AI usage in tokens, API-rate cost and water, without judging it.
Key features
- Automatic Measurement: Mac reads local AI tool logs and iPhone uses Screen Time, so there is nothing to count manually.
- Evening Check-In: A one-tap daily confirmation of personal versus work AI use, with adjustments allowed.
- Pixel Calendar: Each day becomes a pixel colored against your own average, with streaks and a full-year band.
- Usage and Cost (Premium): Tokens, the API-rate cost and estimated water use over today, 30 days and full history.
- Codex Quotas and Widgets (Premium): Quota countdowns plus USAGE and LIMITS widgets.
- Milestones and Friends: 62 milestones and friend trends via QR code or link with no account needed.
- Private by Design: Data stays on device and in your iCloud, with no conversation read and no ads or tracking.
Best for
- Self-Awareness: See how much you rely on AI day to day without being blocked or lectured.
- Cost Tracking: Estimate what your token use would cost at API rates.
- Environmental Awareness: View an estimate of the water behind your AI usage.
- Work-Life Separation: Separate personal AI use from work-hours use.
- Quota Planning: Watch Codex limits and reset countdowns to avoid wasting capacity.
- Group Accountability: Compare trends with friends without sharing exact numbers.
